Roberto Mancini is considering a SHOCK RESIGNATION at Manchester City. The Mail on Sunday says Mancini could quit as Manchester City boss inside a year if he doesn't receive the backing he requires.

A source close to Mancini said: "He has three targets before the window closes - Daniele De Rossi, Maicon and Stevan Jovetic.

"We will see what happens in the next few days. He feels there is no one at the club doing the transfer dealing for him and he has been left with just 19 players for the new season. He is angry, as you can imagine.

"He is ambitious, he has just won the Premier League and wants to win the Champions League. But he can't do that without the right support.

"He isn't about to walk out on City but if nothing else happens before the transfer window closes this could be his last season at City. I wouldn't rule out a move elsewhere next season."
