Samuel Eto'o has once more stuck the boot into Chelsea's Jose Mourinho, by reprising his now-infamous 'Old Man' celebration for Cameroon.
The striker arrived at Stamford Bridge on a one-year deal in 2013 - but while things started serenely enough they soon took a turn for the worse when Jose Mourinho appeared to question Eto'o's age.
During an interview with Canal Plus, the Chelsea manager was recorded - he claims without his permission - as saying: "Eto'o is 32 years old, maybe 35, who knows"
The veteran striker soon got his own back by mocking those questioning his age by hobbling to the corner flag like an old man after scoring for Chelsea in their win against Tottenham at Stamford Bridge last season.
While that appeared to be the end of the matter, the ill-feeling between Eto'o and Mourinho appears to have resurfaced, with the striker labelling the Chelsea boss a "fool" during a recent interview.
Now he's ensured the controversy will continue to rumble on by wheeling out his 'old man' celebration once more, in Cameroon's 2-2 friendly draw against Germany last night.
