Tevez is currently out of action with a hamstring injury and is in a race to recover in time to face Stoke City in the FA Cup final on May 14, and there have been suggestions he may have played his final game as a result.
Tevez, who has recently spent time in Milan receiving treatment on his injury, refused to answer questions when quizzed about a possible move to Inter, and Mancini has now said he will talk to the forward about his plans at the end of the season.
"We need to talk with Carlos [about staying], but we have time to do this," he said. "At the moment, the two most important things are to win the FA Cup and finish in the top four.
"It's more important to know when Carlos can play. Hopefully, after we win the FA Cup and get in the Champions League, we can talk about his position.
"I don't think it depends on getting into the Champions' League, no, but we know how important it is that we finish in the top four and win the FA Cup, for the club."
Mancini also confirmed that Tevez would retain the captaincy upon his return to the side despite Vincent Kompany impressing since taking the armband.
"Carlos will be skipper when he is fit, absolutely," he said. "I cannot say if he will be guaranteed a place, because he has to be 100% fit. If he is it depends for the cup final.
"It's important that we have all the players available. We also have big games in the Premier League. We can't just think of the final, we can't forget the other games in the league. They are very important - more important than the final at this moment.
"If we take a risk because we want to play with Carlos and he's not ready then it can be a problem for him and for us. We don't want that to happen."
