Samuel Eto'o has described Chelsea manager Jose Mourinho as a "fool" for questioning his age and vowed to play on at the highest level for some time to come.
Mourinho, who was also Eto'o's manager at Inter Milan, was caught on camera making unguarded comments suggesting the Cameroon striker was older than his official age earlier this season.
The 33-year-old, in line to feature in his fourth World Cup this summer, responded by celebrating his next Chelsea goal as if he was a geriatric.
Now Eto'o, who is out of contract this summer after scoring 12 Chelsea goals, plans to continue to ply his trade in one of Europe's top leagues.
Eto'o told africanfootball.com: "Thanks for informing me that it will be my last World Cup.
"Today, I am 33 years old. And it is not because a fool called me an old man that you must believe it.
"And you may have noticed that the old man was better than the youngsters.
The 20 most shocking moments of the 2013/14 Premier League season
The 20 most shocking moments of the 2013/14 Premier League season
1/13 Michael Jackson removed, only to reappear elsewhere
Just weeks after buying Fulham from Mohamed Al Fayed, new owner Shahid Kahn decided to remove the most famous statue in football, despite threats from his predecessor that his moustache would be cut off if he dared to do so. Few knew the whereabout of the King of Pop after it disappeared from Craven Cottage, until rather bizarrely the National Football Museum revealed Fayed had donated it to their collection. The eccentric Egyptian owner said the removal of the statue had been the reason for Fulham's relegation.
2/13 Theo Walcott mocks Tottenham fans... twice
Despite being stretchered off with an injury that would rule him out for the rest of the season and the World Cup - Theo Walcott had a big grin on his face as he was carried off the Emirates pitch. That's because he was winding up the visiting Tottenham fans by making a gesture about the 2-0 scoreline. Spurs fans were furious with some pelting Walcott (and those carrying him, even though it turned out some were Tottenham fans) with coins. Despite causing such a furore, Walcott made the same gesture during Arsenal's parade around the pitch after their final home game.
3/13 Ian Holloway walks away
Managers are rarely short of confidence, despite nearly half of them not being deemed good enough and replaced during the course of the season. So it was rather refreshing when Ian Holloway held his hands up, admitted he didn't feel things were working out with Crystal Palace and left the club. At the time Palace had lost seven of their first eight Premier League games. The decision by Holloway was in retrospect possibly the best of the season from the Eagles' point of view, with Tony Pulis coming in and against the odds guiding the club to safety.
4/13 Swansea at war
Six Swansea players were reportedly involved in a fight at the club's training ground - an incident made all the worse thanks to chairman Huw Jenkins happening to witness the clash. While training ground bust-ups are nothing unusual, the frequency with which they happened at Swansea over the course of this season has been. In January a 'screaming Chico Flores' was reported to have picked up a brick during a row with Garry Monk, the man who would later replace Michael Laudrup as manager.
5/13 Alan Pardew
Alan Pardew has always been rather animated on the touchline (just ask Arsene Wenger), but the Newcastle manager took it to a bizarre new level when his team played Hull this season. As David Meyler looked to quickly retrieve the ball from Pardew's technical area, he came into contact with the Newcastle boss. That was enough provocation for Pardew to go and head-butt the defender. It led to his club fining him £100,000 and giving him a warning and the FA banning him from stadiums for three games with a further four-match touchline ban. Quite easily the strangest moment of this, or indeed, any season.
6/13 Cardiff employ Kazakh work experience kid
Vincent Tan is something of an unorthodox club owner - from his leather gloves to disregard for Cardiff fans in changing the club colours from blue to 'lucky' red - but his choice of replacement for Iain Moody after the head of recruitment was sacked was even stranger. The man charged with replacing the experienced Moody was Alisher Apsalyamov, a 23-year-old from Kazakhstan who had been at the club on work experience over the summer. Apsalyamov, reportedly a big fan of Fifa and a friend of Tan's son, didn't last long in the role due to problems with his work visa.
7/13 Chris Hughton sacked
That Chris Hughton was sacked during the season came as little surprise. But that Delia at the Norwich board left it so late was bizarre. There were just five games of the season remaining when it was deemed a change was needed, so out went Hughton and in came youth coach Neil Adams. At the time the Canaries were five points clear of the relegation zone. Before the season was over they were relegated.
8/13 Luis Suarez becomes likeable
Having missed the first six games of the season due to biting an opponent, changing opinions seemed an impossible task for Luis Suarez. But across the season the Liverpool striker has been the best player to watch, hitting the 30 goal barrier in the process. The Uruguyan's redemption was confirmed with the two highest individual honours - the Football Writers' Award and the PFA Players' Player of the year.
9/13 The quenelle
When Nicolas Anelka made a gesture during a match around Christmas time it went largely unnoticed, probably because people were more in shock that he had actually found the back of the net for West Brom. But it turned out the gesture, dubbed the 'quenelle' or an 'inverted nazi salute', is deemed by anti-semitic by some. It led the FA to issue the Frenchman a five-match ban and £80,000 fine. Meanwhile the Baggies sacked him for gross misconduct. Despite Anelka having played for half the teams in England, no-one seemed particularly sorry to see him go.
10/13 Mark Clattenburg upsets Adam Lallana
Mark Clattenburg, something of a moth to the limelight, found himself the centre of attention for what seemed to most an innocuous remark. While officiating a Southampton match, he allegedly told Adam Lallana: 'You are very different now, since you've played for England - you never used to be like this.' It was enough for Saints to lodge an official complaint and suggest that Clattenburg had insulted their player and should not referee their games again. The official was cleared of any wrongdoing.
11/13 Steven Taylor Twitter gaffe
Steven Taylor escaped FA action, but needed to be reminded of his responsibilities after an ill-judged tweet. In response to being mocked by team-mates over his poor French, The Newcastle defender tweeted a picture of Massadio Haïdara along with some 'look-a-likes' - two other black players - Papiss Cissé and Moussa Sissoko - as well as a tribesman. It was accompanied by the words 'it's always good to see you guys smiling'.
12/13 Tom Huddlestone haircut
Tom Huddlestone's hair was getting out of control. But having vowed not to cut it until he found the back of the net, it just kept getting bigger. So when the Hull midfielder ended his 32-month goal drought in the 6-0 win over Fulham (a game possibly deserving of it's own mention in this countdown) the barber was called in. In front of the photographers in the KC Stadium changing rooms, his unwieldy hair was trimmed and in the process a lot of money was made for charity.

13/13 Arsenal get smashed - again and again
Arsenal were genuine title contenders for much of the season, but defeats to the top sides saw their challenge come undone. Losing to the teams at the top isn't unforgivable, but the manner of many of the defeats was shocking. Over the course of the season, Arsene Wenger's side lost in equally disastrous circumstances to the other three teams in the top four, going down 6-3 to Manchester City, 5-1 to Liverpool and 6-0 to Chelsea.
"Some believe I am going to retire in the United States or in the Middle East, but I have regained the joy of the Champions League and I am going to carry on playing in the Champions League. Where? I am not going to tell you.
"But I am going to carry on playing because physically and mentally I feel great.
"So I am going to go to this World Cup and to the next one when I will be 37.
"Some did it at 42, so I can still play in two more World Cups."
Following Chelsea's final game of the season at Cardiff, Mourinho suggested Eto'o would depart this summer, at the end of his one-season deal.
The Chelsea boss will wait until pre-season before determining the futures of his loan stars.
Mourinho presented his end-of-season report to the Chelsea hierarchy on Monday, detailing his thoughts on all matters relating to the first-team squad.
Definitive decisions on goalkeeper Thibaut Courtois, striker Romelu Lukaku and the others who spent time away from Chelsea this season will wait until after training resumes on July 8.

Mourinho to decide on loan stars in pre-season
Courtois has impressed in his third consecutive season on loan at Atletico Madrid, helping the Spaniards to the May 24 Champions League final at the expense of his parent club, and could put pressure on Petr Cech as Chelsea number one.
Lukaku spent a second straight season on loan in the Premier League, scoring 17 goals for Everton - a tally greater than any of the strikers who remained at Stamford Bridge.
Others will also be looked at closely by Mourinho, including Victor Moses, who spent the season at Liverpool, and Marko Marin, who helped Sevilla to win the Europa League.
After Chelsea's final home game of the season, Mourinho insisted there was no rush to make decisions relating to his squad.
Tellingly, though, captain John Terry signed a one-year contract extension 24 hours after Mourinho's report was submitted.
The fates of record goalscorer Frank Lampard and left-back Ashley Cole are still to be clarified, with their contracts expiring imminently.
