Manchester City goalkeeper Joe Hart told Carlos Tevez to leave the wall ahead of Robin van Persie's winner for Manchester United on Sunday, it has been revealed.

The Daily Mail says it emerged on Monday that City goalkeeper Hart asked Tevez to leave the defensive wall prior to Van Persie's winner.

City manager Roberto Mancini was bemused by the sight of Tevez leaving his position next to Samir Nasri, in what had been a four-man wall, before Van Persie struck his free-kick.

In a heated dressing-room inquest, Hart is understood to have told Mancini that he told Tevez to move as he could not see. Hart's view was that Nasri was in a perfect position to block Van Persie's shot and would have done so had he not then moved out of the way.
