May 14 - Roberto Mancini (Man City)
A year to the day after delivering the Premier League title, Roberto Mancini was sacked by Manchester City. The official reasons given by the club were the Italian's failure to meet 'stated targets' and a desire for a more 'holistic approach'. The decision to part with the former Inter Milan boss came days after City's FA Cup final defeat to Wigan. That match at Wembley was the culmination of an under whelming season which had seen City's attempts to retain their title fail with a whimper and a Champions League campaign that came to an end in the group stage for the second year running. Mancini lasted three-and-a-half years at the club and as well as winning the Premier League, also delivered the 2011 FA Cup.
May 9 - John Hughes (Hartlepool)
Hughes lasted just six months in charge of League One side Hartlepool after being appointed as Neale Cooper's successor. When he took the reigns, Pools were bottom of the league and on the back of a 16-game losing streak. Yet the former Falkirk, Hibernian and Livingston manager was unable to turn it around and the club were relegated with three games of the season to go. Pictures is a general view of Hartlepool's Victoria Park.
May 7 - Kenny Jackett (Millwall)
Kenny Jackett was among the longest serving managers in English football after six years at the helm of Millwall, but after a season in which they reached the FA Cup semi-finals but also only avoided relegation from the Championship by just two points, the 51-year-old decided it was time to step down. Chairman John Berylson was keen to keep Jackett at the club after becoming close with the manager during his tenure
May 7 - Dean Saunders (Wolves)
Dean Saunders left Doncaster to become manager of struggling Wolves but after winning just five of his 20 matches in charge, was unable to save the club from their second relegation in as many years. Saunders made clear he wanted to stay on as manager but the club opted to look for a new man to take the helm in what will be their fifth appointment in little more 15 months.
May 3 - Brian Flynn (Doncaster)
Flynn had been in charge of Doncaster after Dean Saunders left to take charge of Wolves in January and led the club to promotion to the Championship after Doncaster finished the season as champions of League One. Flynn stood down as manager to move into a director of football role at the club.
April 30 - Leam Richardson (Accrington)
The Accrington boss left his role as manager to become Paul Cook's assistant at fellow League Two side Chesterfield. Richardson was appointed manager in November when he stepped up from being Cook's number two when the latter left for Chesterfield. Richardson won 10, drew 11 and lost 15 of his 36 matches in charge.
April 29 - Martin Ling (Torquay)
After being appointed in June 2011, Torquay sacked Ling. The former Leyton Orient and Cambridge boss had been away from the club since January because of a stress-related illness, however the decision was based solely on results according to the League Two club.
April 10 - Danny Wilson (Sheffield United)
Despite the club being just six points off an automatic promotion place from League One, the Blades parted company with Wilson with just five games of the season remaining. The manager's final game in charge was a 2-0 defeat to Crawley at the end of a patchy spell of form.
April 1 - Neil Warnock (Leeds)
After defeat to Derby County ended Leeds United's faint hopes of promotion from the Championship, Warnock left the club. Having taken over 14 months previously, the former Sheffield United boss was charged with bringing top flight football back to Elland Road. Warnock was always expected to leave at the end of the season if they failed to gain promotion but a run of three defeats in his final three games speeded his exit. Speaking just before his exit, Warnock said: 'I have been a manager for 33 years and these last 12 months have been the hardest. I have given it my best shot, but, being honest, we haven't been good enough in the final third of the pitch.'
March 30 - Martin O'Neill (Sunderland)
Martin O'Neill was sacked hours after a 1-0 home defeat to Manchester United in one of the most surprising decisions of the season. The highly respected former Celtic and Aston Villa manager had only taken charge 16 months previously and in his first season steered the club away from the relegation zone. Over the summer, the Black Cats invested in the side, spending around £30m, but results did not improve. The defeat to United meant the club had gone eight matches without a win, during which time they picked up just three points. O'Neill, who supported the club as a boy, left the club just one point above the relegation zone.
March 20 - Gary Smith (Stevenage)
Smith lost his job after a 2-0 defeat to struggling Bury - it was a result that meant Boro had lost 14 of their past 18 games. The slide has seen Stevenage fall from a play-off place down to 15th in the League One table. Smith joined Boro in January 2012 and led the club to a play-off semi-final, where they were beaten by Sheffield United.
March 19 - Michael Appleton (Blackburn)
Appleton would last just 67 days at Ewood Park before he was sacked. After making a decent start, a run of eight games without victory, including a quarter-final FA Cup exit to Millwall, saw the former Blackpool manager lose his job. He left the club with Blackburn 18th in the Championship - four points above the relegation zone.
March 11 - Brian McDermott (Reading)
McDermott became the fourth Premier League manager to be axed during the season when the Reading owner Anton Zingarevich deemed 'a change was neccessary'. McDermott had led the Royals to promotion from the Championship last season having taken over on a caretaker basis in 2009. He was given the job permanently a year later. He leaves Reading 19th in the Premier League - four points from safety.
March 2 - Gary Mills (York)
A 2-0 home defeat by Bradford City would be Mills' last game in charge at Bootham Crescent. It was a result that meant York had only collected six points from their last 11 games. The much-travelled former Nottingham Forest and Leicester midfielder was appointed manager in October 2010 and won promotion from the Conference via last season's play-offs.
February 26 - John Still (Dagenham)
John Still was the fourth longest serving manager in England behind only Sir Alex Ferguson, Arsene Wenger and David Moyes when he opted to leave League Two side Dagenham. The 62-year-old ended his nine-year spell at the club to take up the vacancy at non-league Luton.
February 18 - Paolo Di Canio (Swindon)
The outspoken Italian resigned his post at the League One side citing 'a number of broken promises' relating to the takeover of the club. Swindon's board said they were 'disappointed' the 44-year-old had left. The former West Ham player guided the club to promotion from League Two last season, and within three points of the summit of League One at the time of his departure.
February 13 - Graham Westley (Preston)
A 3-1 defeat at Yeovil would be Graham Westley's last match in charge of the League One side, with the board feeling the need to act with the Lilywhites just five points above the relegation zone. The former Stevenage boss had been in charge for 13 months.
February 5 - Alex McLeish (Notts Forest)
While an unpopular appointment among Nottingham Forest fans, few would have predicted Alex McLeish's reign to last just 41 days. The former Aston Villa manager left by mutual consent due to 'a difference of understanding of the development strategy' at the club. The Scot was reportedly furious over the owners' dealings in the transfer window in which Forest missed out on a number of targets. McLeish oversaw seven matches, winning just one and losing four.
February 3 - Keith Curle (Notts County)
Keith Curle was in charge less than a year before he was sacked - leaving the League One side in 10th position and five points away from the play-offs. A run of just two wins in 11 matches had undermined what had been a fine start to the season and the board made a decision that was not 'taken lightly and certainly not one that I have taken any pleasure in reaching' said chairman Ray Trew.
February 3 - Paul Dickov (Oldham)
Despite a famous victory over Liverpool in the FA Cup just a week before, Oldham's league form was poor enough that Paul Dickov took the decision to 'step aside'. In his first managerial role, Dickov took over at Boundary Park in June 2010. In his two full seasons Oldham finished 17th and 16th - and he left the club just one point above the League One relegation zone.
January 24 - Simon Grayson (Huddersfield)
12 games without a win is cause for concern, and for the Huddersfield board, it was cause to do away with their manager. Grayson had guided the Terriers to promotion from League One last season after they came through the play-offs, but their return to the Championship proved difficult. Grayson left with the club 18th in the league - seven points above the relegation zone.
January 21 - John Coleman (Rochdale)
John Coleman was sacked by the League Two side 12 months after taking charge. In his first season he was unable to save Rochdale from relegation to League Two, and with hopes of immediately bouncing back dashed by some dreadful form, the board took the decision to act.
January 18 - Nigel Adkins (Southampton)
Perhaps the biggest shock of the season came at St Mary's where the popular Nigel Adkins was shown the door. After guiding them to the Premier League with back-to-back promotions, Southampton were just beginning to settle in the Premier League after a dreadful start. But his two-and-a-half year spell on the south coast was ended when the owners felt Argentine Mauricio Pochettino would do a better job.
January 12 - Derek McInnes (Bristol City)
A 4-0 defeat to Leicester that left Bristol City bottom of the Championship was enough to see Derek McInnes shown the door. Earlier in the season the Scot had overseen a club record-equalling seven-game losing run. McInnes took over at Ashton Gate in October 2011 and in his first season guided them to safety with one game to spare.
January 11 - Michael Appleton (Blackpool)
Just two months after taking charge at Bloomfield Road, Michael Appleton jumped ship for Blackburn Rovers. The former Manchester United and Preston midfielder began the season at League One Portsmouth before taking charge of the Seasiders. Appleton won two and drew seven of the 11 league games he was in charge for.
January 7 - Dean Saunders (Doncaster)
Dean Saunders left Doncaster to replace Stale Solbakken at Wolves. His time at the League One side was brief. During his first season in charge he was unable to save them from relegation, despite drafting in some high-profile loan signings. Doncaster's bid for a return to the Championship was going strongly this season, with the side joint-top of League One at the time of his departure.
January 5 - Stale Solbakken (Wolves)
Solbakken always felt like an unlikely appointment as Wolves looked to make an immediate return to the Premier League, and it proved to be an unwise choice after the Norwegian was sacked just over six months after taking charge. The club were sitting in 18th in the Championship at the time of his dismissal, but it was a shock defeat to Luton in the FA Cup that triggered the Molineux board to act.
January 1 - Carl Fletcher (Plymouth)
Defeat to Bristol Rovers was the last straw for the board at League Two side Plymouth Argyle. Flether lasted just 16 months as manager having initially taken over on a caretaker basis. He left the club just two points clear of the relegation zone.
December 29 - Keith Hill (Barnsley)
Keith Hill was sacked by Barnsley after defeat at home to Blackburn saw them drop to the foot of the Championship. The former Rochdale boss had been in charge for 18 months. "We've had a pretty rough time results-wise over the last few months and the board decided we have to do something positive in order to try and retain our status in the Championship," said general manager Don Rowing. In 75 matches under Hill, Barnsley won just 19.
December 28 - Mark Robson (Barnet)
Following the appointment of Dutch legend Edgar Davids (pictured) as joint head coach, it always seemed unlikely a relationship would blossom between him and Mark Robson. And so it proved.
A club statement read: "It was felt that clarification was required regarding the coaching responsibilities at the club and to this end it was agreed that Mark should leave with immediate effect."
Robson had taken charge of the League Two side in the summer.
December 27 - Henning Berg (Blackburn)
Having given Steve Kean far too long (according to most Blackburn fans), Henning Berg was not afforded the same treatment by Blackburn's owners.
The former Rovers defender lasted just 10 games and 57 days in charge at Ewood Park - recording just one win in the process.
December 26 - Sean O'Driscoll (Nottingham Forest)
Sean O'Driscoll was given just five months in charge of the Championship side - and seemingly harshly sacked considering his last match in charge was a 4-2 victory over Leeds.
Although O'Driscoll won 10 games during his reign, he also lost seven and with the club in eighth Forest chairman Fawaz Al Hasawi felt a change was needed - with the lack of consistency a part of his thinking.
"We knew when we bought the club in the summer that it would take time for the players we bought in to settle but that process has taken longer than we anticipated," said Al Hasawi.
"We feel we have developed a really strong squad of players but are still searching for consistency in terms of team performance, underlined by the fact that we have not won more than two games in succession in the Championship this season."
December 15 - Mark McGhee (Bristol Rovers)
Having not won a match for over a month and only four in 22 games, Mark McGhee was shown the door.
The former Reading and Wolves manager had taken charge of the club in January, but failed to turn things around, leaving with the club second bottom in League Two.
"We have decided that we can no longer continue with the current situation and had to make the difficult decision to part company with Mark. We decided we had to act now before it was too late," said chairman Nick Higgs.
December 1 - Micky Mellon (Fleetwood)
Having led Fleetwood into the Football League for the first time in their history in April, Mellon did not last long as a League Two manager.
Initially coaching the Highbury club on a part-time basis, Mellon took on the role full-time in 2009. He led them to the Blue Square Bet Premier via the play-offs in 2009/10 and then guided them to a haul of 103 points and promotion to League Two last season.
Mellon's sacking came with Fleetwood sitting in seventh spot, just 10 points behind leaders Gillingham.
November 23 - Mark Hughes (QPR)
Despite chairman Tony Fernandes consistently stating Mark Hughes' job was safe, a failure to win a single game in 12 Premier League matches finally told for the Welshman.
The former Fulham manager had joined the R's 10 months earlier, escaping relegation on the final day of the 2011/12 season only by virtue of results elsewhere.
The summer saw a huge influx of expensive players but they failed to gel, leading to Hughes' downfall.
"The circumstances we find ourselves in have left the board of directors with very little choice but to make a change," the club said in a statement.
21 November 2012 - Roberto Di Matteo (Chelsea)
Chelsea legend Di Matteo was ruthlessly dismissed from his position as manager following the club’s humiliating 3-0 loss to Juventus in the Champions League group phase. The Italian’s risky tactics, dropping Fernando Torres in favour of playing Eden Hazard as a ‘false 9’ backfired.
Aside from this season’s European struggles, Di Matteo enjoyed a very successful, if brief, career as Chelsea manager, winning the Champions League and FA Cup last season.
Di Matteo originally returned to Chelsea in the capacity of assistant manager to Andre Villas-Boas, but was made interim manager following the latter’s sacking last March. 42 games later, he leaves Chelsea four points behind league leaders Manchester City in third place, and departs with a win percentage of 57.14 in all competitions.
7 November 2012 - Michael Appleton (Portsmouth)
Appleton was lured to the vacant managerial position at Blackpool following Ian Holloway’s departure in November. Appleton’s Portsmouth had fallen into administration in February for the second time in two years, and their relegation from the Championship at the end of last season made his to choice to join Blackpool an easy one.
The former Manchester United trainee had been offered the Pompey job in November last year after his spell as West Brom caretaker managed following Roberto di Matteo’s dismissal. His first game in charge of the club, a 2-0 loss to Watford, rather set the tone for the rest of his fist official managerial appointment.
3 November 2012 - Ian Holloway (Blackpool)
The charismatic Bristolian left Blackpool after 161 games in charge to take the reins at high-flying Crystal Palace in November this year. During his time at the Tangerines, Holloway guided the club to the Championship play-offs on two occasions, taking full advantage of the first of which by sealing promotion to the Premier League in 2010.
Blackpool were relegated from the top flight after one season but had won the hearts of many a football fan with their exciting style of play and Holloway’s entertaining interviews.
Holloway left Blackpool in 12th place in the Championship table, six points adrift of Crystal Palace, and departed with a league win percentage of 37.8 from 143 games.
October 29 - Alan Knill (Scunthorpe)
A ninth loss in 15 league games was the final straw for Scunthorpe who fired Alan Knill. The former Iron player had a dreadful record of just 16 wins in 78 games after taking charge back in March 2011. Knill was unable to save Scunthorpe from relegation in his first season and could only finish 18th in League One the following year. He departed with the club 22nd in the table.
October 26 - Paul Cook (Accrington)
Paul Cook departed Accrington Stanley to join League Two rivals Chesterfield. It was to be a short stint for the 45-year-old at the Fraser Eagle Stadium, having only joined the Lancashire outfit from League of Ireland side Sligo Rovers back in February. In his 33 matches in charge Cook won eight games, and lost the final four.
October 24 - Paul Jewell (Ipswich)
Following a 2-1 defeat to his former club Derby County, Paul Jewell was shown the door - 10 matches on from Ipswich's solitary league win this term against Watford. That final defeat saw the Tractor Boys hit the bottom of the Championship and it was quickly announced that he had left by mutual consent. Jewell, who has also managed Bradford and Wigan, took charge at Portman Road in January 2011.
October 23 - Dougie Freedman (Crystal Palace)
Although there was some confusion over whether Dougie Freedman had joined Bolton as their new manager, there was no doubt he had left Crystal Palace after the club issued a statement with the usual "good luck and thanks for all your hard work" message. Palace had enjoyed a good start to the season under Freedman, who had been appointed their permanent manager in January 2011. He left them fourth in the Championship, opting to take the vacancy at Bolton, who were ten places below at the time of his departure.
October 12 - Eddie Howe (Burnley)
Eddie Howe took the decision to re-join Bournemouth, having only left the Cherries for Burnley in January 2011. The 34-year-old's decision was based on "personal and family reasons". Howe left Burnley in 16th place in the Championship.
October 9 - Owen Coyle (Bolton)
Having taken over at the Reebok in January 2010, Owen Coyle would see Bolton relegated the following season in a campaign which will be remembered for the heart-attack suffered by midfielder Fabrice Muamba. Bolton targeted an immediate return to the Premier League but with the club in 18th position after 10 games, the former Burnley boss was shown the door.
October 3 - Paul Groves (Bournemouth)
Paul Groves was only given the Bournemouth job on a full-time basis in May 2012, but a poor run of results which ended with a 3-1 defeat to Crawley, led to his dismissal. "I believe that luck has not been on their side during their short period at the helm," said the Cherries' chairman. Groves left with Bournemouth fifth from bottom in League One.
September 28 - Steve Kean (Blackburn)
For all the calls for Steve Kean to be sacked as Blackburn manager, in the end the Scotsman walked. Having replaced Sam Allardyce after the arrival of new owners at Ewood Park, Kean struggled from the outset. As Rovers tumbled down the Premier League and fierce opposition to his reign from supporters grew, somehow he held on to his job. Blackburn were relegated. Despite a strong start to the season the 44-year-old said he had been 'forced to resign'.
September 24 - John Ward (Colchester)
Without a win and just four points from their opening eight league games, Colchester sacked John Ward. Ward had been at the helm at the Weston Homes Community stadium since May 2010 and has delivered back-to-back top-10 finishes in the third tier. "So much of Colchester United is better than it has ever been, but sadly that is not being reflected in first-team results," said chairman Robbie Cowling.
September 22 - Gary Waddock (Wycombe)
Three successive defeats, the last of which was a 1-0 loss to AFC Wimbledon, were enough for Gary Waddock to be shown the exit. four points from their opening seven games was simply not enough for the hierarchy at Adams Park. Waddock led the club to promotion from the basement division in the 2010-11 campaign but they were relegated at the end of last season.
September 19 - Terry Brown (AFC Wimbledon)
Terry Brown led AFC Wimbledon to three promotions in the space of four seasons to see them reach League Two in 2011. But a poor start to this season, in which they had not won since the opening day, was enough for the club to feel a change at the helm was needed. "It is not a time for being despondent about leaving the club, it is time to remember the fantastic times that we have had here," said Brown, who guided the club to a 16th place finish on their return to the Football League.
August 28 - John Sheridan (Chesterfield)
The 2011/12 season was a mixed one for John Sheridan in which relegation from League One was coupled with a Johnstone's Paint Trophy triumph at Wembley. He was retained for the current campaign, but not for long. Three games into the season - with a defeat and two draws to Chesterfield's name - Sheridan was sacked. The former Leeds United player joined the club at the start of the 2009/10 season and won promotion the following year.
August 26 - Andy Thorn (Coventry)
The first managerial departure of the season came at Coventry - where three straight draws were deemed unacceptable. Andy Thorn, who joined the club in April 2011, paid the price. Tim Fisher, the club's chief executive, said: “We have not taken this decision lightly. We recognised that last season there were off-the-field matters that affected team affairs and felt it was right and proper to give Andy the chance to put that right over the course of the summer and the start of the season. We do not feel that has happened." Thorn presided over Coventry's relegation from the Championship last season.
