Manchester City manager Roberto Mancini has accused Argentine striker Carlos Tevez of "behaving stupidly" by refusing to warm up during the Champions League tie with Bayern Munich.

"Tevez behaved stupidly in the way a player shouldn't, especially a great player. I was really angry, because I was not expecting that from him. I always had excellent relations with him," Mancini said.

"That's the first time I've seen that in such an important match. You can always get things wrong, but you only realise it. In Tevez's case, I did nothing for him to behave in this way," he added.

"Ten days after what happened in Munich, I invited him to come to my place to talk. I told him that if he apologised, he could come back into the squad. But he replied that he didn't have to apologise to anyone," Mancini added.

City needs to defeat The Reds on December 7 and hope Napoli drop points against Villarreal in Spain if it is to qualify for knockout stages, The Telegraph reports.

The lucrative knockout stages would be crucial in boosting City's to meet Union of Football Associations' (Uefa) Financial Fair Play regulations and reduce losses to 38.5 million pounds within three years if it wants to participate in future European tournaments.

Uefa's guidelines, which would apply to all clubs competing in European competitions from the 2014-15 season, aim to reduce the reliance of clubs on wealthy owners. (ANI)
