Mancini believes the striker will stay because nobody wants to sign him.
Tevez handed in an official transfer request earlier this summer, but returned to training at Eastlands on Monday.
“It is two weeks until the end of the market,” said Mancini. “I think it is difficult for him to leave.
“I don’t know if he will stay but at the moment, there isn’t a team who want to take him.
“I would be happy if he stays.”
