Manchester City boss Roberto Mancini says they're already one of the best clubs in the world.

City have made considerable progress since Mancini took charge almost two years ago, winning the FA Cup last season and launching a serious Barclays Premier League title bid this term.

He said: "I started to work here two years ago.

"I have worked hard to build a good team and I think I would like to stay here another three or four years because I think in this moment Manchester City is one of the best clubs in the world."
