The striker does not appear to have a future at City and has been absent from the club for the past month. AC Milan revealed they had been given permission by City to speak to representatives of the player on Monday.
Mancini, speaking at a press conference ahead of Wednesday's Champions League clash against Bayern Munich, said: "I don't know what the situation with Carlos is in this moment. I think for us it is important to sell him. We can do this, to sell Carlos, for him and the club. If he has a chance to go to Italy I am happy for him."
Tevez's advisor, Kia Joorabchian, has stated that his client's priority is to secure a move to another European club.
The 27-year-old has again been linked with his former club in Brazil, Corinthians, but after a move there collapsed in the summer, he is concentrating elsewhere.
"A return to Brazil? It's a possibility, but for the time being he wants to play in Europe," Joorabchian told www.milannews.it.
Tevez returned to Argentina without City's permission after deciding not to appeal against a club fine for five breaches of contract relating to his conduct on the bench against Bayern Munich on September 27. Joorabchian says Tevez is now working hard away from the club ahead of a possible move.
He said: "He is training intensely. In January he wants to return to have a starring role and play in a great club."
Joorabchian also confirmed other clubs aside from Milan are interested in Tevez. Inter Milan and Juventus have also featured in reports.
Joorabchian said: "Milan is a great club but there are other Italian clubs that have also requested information."
