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.
"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.
