Mancini unsure of Man City stay for Tevez
Tevez spoken of his wish to return to Argentina, Mancini cannot be sure that signing the extension will happen.
"I don't know what will happen in the summer," said Mancini.
"Carlos has another year on his contract but many times he has said he wants to go back to Argentina.
"It depends on him. At this moment we can say nothing.
"Our focus should just be on the last two months."
