Yet with no new offers Mancini is expecting him back and to play a full role at the Etihad Stadium from next week.
"He doesn't have another team," said Mancini when asked about reports of a swap deal involving Inter right-back Maicon.
"Carlos is a professional player. If he doesn't have another team in the next 10 days or two weeks I think he will play for us and play serious like last year, like always."
When asked whether Tevez was likely to move before the transfer deadline at the end of the month, Mancini added: "I don't know. A lot can happen in one month but if he stays I am happy."
The rumours linking City with Maicon highlight a lack of cover for first-choice right-back Micah Richards.
Because of that Tevez's international team-mate Zabaleta has returned to training and will be available to play at Wembley on Sunday.
Mancini said: "Zaba is here because if we had a problem with Micah we have only one fit right-back."
