Manchester City boss Roberto Mancini admits Carlos Tevez went missing for Robin van Persie's winner.

It was Tevez's half-cleared corner that led to Pablo Zabaleta's equaliser, although there was some confusion about where the Argentina star should have been for Van Persie's fateful free-kick given he moved away from his place in the wall to try and mark Rooney, who had become the sixth - and youngest - player to reach 150 Premier League goals.

"I don't know what happened," said Mancini. "I understood before it was dangerous that free-kick and we made a mistake by only putting three players in the wall.

"I called Carlos to come back into the wall but from the bench I was too far away."
