Three goals in two games for City should help him find a new home, away from Old Trafford.
"I don't think about a new contract with Manchester United because I'm focused on Birmingham," said the Italian. "We will see what happens on May 3.
"I hope I get a goal a game, it will help but that is not really on my mind.
"I spoke with David Moyes before I came. I said I wanted to go to Birmingham and he agreed, so that was that."
