Manchester City boss Roberto Mancini confesses Robin van Persie has made the difference at Manchester United this season. Van Persie hit the winner in yesterday's derby just months after snubbing City for United.
"The player shooting was Van Persie and he shot very well. I called Carlos to return to the wall, but I was too far away on the bench," said Mancini.
"Van Persie scores against every team and once United signed Van Persie they improved a lot. But we have four great strikers and we can win the title again this year."
