The Cameroonian, who turned 33 on March 10, hasn’t enjoyed being the butt of jokes since the Blues manager questioned his birth certificate on French TV.
As a result, Eto’o is determined to leave Stamford Bridge when his one-year contract runs out at the end of the season, with The Sun on Sunday claiming former club Real Mallorca is his likeliest destination.
Mourinho’s offending comments came last month when he said: ‘The problem is I lack a scorer. I have Eto’o but he is 32, maybe 35, who knows?’
An ex-lover of the striker’s, Anna Barranca, then rubbed salt into the wounds by telling newspapers his real age was more like 39.
When Eto’o celebrated his birthday, he made a point of emphasising his age to his Twitter followers, writing: ‘Dear All. Thank you so much for all the birthday wishes. It means the world to me. 33. Jesus Christ Age!’
Eto’o scored the first goal against the Gunners on Saturday before hobbling off injured in the tenth minute.
