Tevez has been frozen out of the first-team picture since Mancini claimed the Argentinian refused to play in the Champions League game at Bayern Munich back in September.
Mancini has spoken little about the subject since the night in question, but in an interview yesterday ahead of tonight’s Champions League clash against Villarreal, he said: “Everything depends on Carlos. If he apologises to the squad and to me then everything will be as before.
“If he doesn’t, then Tevez has a value that everyone knows and something will happen in January.
“He is totally unprepared and being badly advised. I don’t want it to be like this and I would be the first to forgive him.”
Mancini also revealed that the club turned down the chance to sell controversial 21-year-old striker Mario Balotelli back to Italy this summer.
The former Inter Milan star endured a turbulent debut campaign in England, but has thrived this time around and already has six goals to his name, rewarding Mancini for the faith he has shown in him.
“Sooner or later Balotelli will go back to Italy,” said the City boss. “However, it won’t happen for a few more years and it will do him good to remain here.
“We did receive offers for him from Italian clubs over the summer, but we don’t sell anybody here.”
