Tottenham have appointed Mauricio Pochettino as the club's new manager on a five-year deal.
The club were in advanced talks with the Southampton manager over the last few days and have now confirmed the Argentinean as the permanent successor to Tim Sherwood who was sacked at the end of the season.
Writing on the club's official Twitter account Spurs announced: "The Club is delighted to announce the appointment of Mauricio Pochettino as our new head coach on a five-year contract."
In a statement on the club's website, Pochettino said: "This is a club with tremendous history and prestige and I am honoured to have been given this opportunity to be its head coach.
"There is an abundance of top-class talent at the club and I am looking forward to starting work with the squad.
"Tottenham Hotspur has a huge following across the world and I have great admiration for the passion the fans show for this team. We are determined to give the supporters the kind of attacking football and success that we are all looking to achieve."
Commenting on the appointment Tottenham chairman Daniel Levy said: "In Mauricio I believe we have head coach who, with his high energy, attacking football, will embrace the style of play we associate with our club. He has a proven ability to develop each player as an individual, whilst building great team spirit and a winning mentality.
"We have a talented squad that Mauricio is excited to be coaching next season."
Pochettino emerged as the front-runner soon after the dismissal of Sherwood, although there were other names in the frame. David Moyes, Frank de Boer and Carlo Ancelotti were all linked with the vacancy but Spurs saw the Southampton manager as the best choice.
Tim Sherwood's most entertaining moments
Tim Sherwood's most entertaining moments
1/6 Sherwood finds a replacement
In what was his final game in charge of Tottenham, in one of the funniest moments of the season, Sherwood invited a fan to take his place in the White Hart Lane dugout towards the end of the 3-0 victory over Aston Villa. Sherwood then directed the supporter to his own seat and gave the fan his famous gilet to wear. Sherwood explained afterwards: 'That guy sits up there every week I'm here, and he's telling me: 'Get him off he's rubbish, he's an embarrassment, he's this, he's that', so I invited him down to show what he can do. He half-bottled it at first but in the end he took it up.'
2/6 Saluting Adebayor
Cringe! When Sherwood replaced AVB the first thing he did was recall Emmanuel Adebayor. It worked out great with the striker banging in the goals on his return. Sherwood couldn't hide his pleasure when the Togo forward scored against Sunderland, giving his player a salute which was returned.
3/6 Fighting with Jesus
Sherwood accused his Benfica counterpart Jorge Jesus of 'lacking class' following their meeting in the Europa League. For some bizarre reason Jesus waved three fingers in Sherwood's direction after his side scored a late goal to make the score 3-1 at White Hart Lane. It stemmed from Jesus shooing Sherwood out of the Benfica technical area earlier in the match. The pair didn't shake hands at full-time.
4/6 Gilet throwing
The gilet received almost as much attention as Sherwood during his brief reign. It was the fashion choice that divided the football world. Whether Sherwood decided he'd had enough of it or was angry at seeing his side concede an early goal to local rivals Arsenal, either way he threw it in down the tunnel.
5/6 Criticising his players
The former Blackburn captain had no qualms about openly criticising his players and at one stage told them all that they were playing for their futures. He explained: 'I'm a manager, not a babysitter'.
More than anything else, Sherwood will be remembered for speaking his mind while in charge of Tottenham. Just last weekend, with speculation over his future increasing, he was happy to explain how he saw the situation: 'I am doing this job with a lot of uncertainty around my future,' he said. 'If you have a supply teacher who comes into your school, sometimes they are not treated with the respect that a headmaster is.'

One advantage of appointing the Argentinean is the potential he brings to coaxing the best out of Tottenham's record signing and his compatriot Erik Lamela who endured a dreadful first season after his £30m move from Roma.
The appointment is also likely to lead to speculation that Tottenham can poach Southampton midfielder Adam Lallana from the clutches of Liverpool who have been persuing the England international since the season ended.
Pochettino arrived in the Premier League to replace Nigel Adkins 18 months ago. Although some questioned the appointment, he proved any doubters wrong as he led the Saints to their highest-ever Premier League finish last season as well as overseeing the progress of home-grown players including Luke Shaw, Lallana, James Ward-Prowse and Calum Chambers.
Some will be surprised by the length of contract handed to Pochettino, particularly considering the trend of quick dismissals at the club following the departure of Harry Redknapp.
The announcement means Southampton are now seeking a new manager. Michael Laudrup, Malky Mackay and Murat Yakin are among the favourites for the role at St Mary's.
Pochettino had a year remaining on his deal at St Mary's and has taken with him assistant manager Jesus Perez, first-team coach Miguel D'Agostino and goalkeeping coach Toni Jimenez.
It is unclear what those appointments mean for Spurs' existing backroom team, while there have been reports questioning the future of technical director Franco Baldini.
What is certain, though, is that Pochettino will be charged with securing Spurs a top-four finish by ambitious chairman Daniel Levy after a disappointing campaign, in which a flurry of summer signings failed to gel.
