Not one to shy away from controversy, Osborne is the latest to have a pop at Chelsea boss Mourinho.
The actor / vocalist is an avid Real Madrid supporter who was highly critical Mourinho during his three-year tenure as manager at the Bernabeu between 2010 - 2013.
The self-proclaimed Special One’s final year in Madrid was controversial and marred with rumours of a return to Chelsea, and his departure last summer was met with a degree of relief by certain sections of the fans.
Mourinho returned to the Spanish capital, however, somewhat sooner than expected, as his Chelsea side took on Atletico Madrid in the Champions League semi-final first leg at the Vicente Calderon stadium on Tuesday.
The match finished goalless, and while Chelsea's defensive tactics were praised in some quarters, Osborne was not impressed and stated he would sack Mourinho immediately if he were the Chelsea owner:
'I think that Atletico Madrid have a difficult task (to progress) and I’m very sorry because I’m fully behind them', Osborne was quoted by Spanish media outlet AS.
'For now, Mourinho doesn’t deserve to be a football coach. If I was the owner of Chelsea, I would sack him immediately after the sorry debacle which happened at the Calderon'.
Despite his anger at Chelsea’s display under Mourinho, Osborne did warm to the idea of Chelsea progressing to the final in Lisbon and meeting his Real Madrid there.
'That said, I would love a Real Madrid - Chelsea final to crush Mourinho in Lisbon, in his own home', he continued.
