Sir Alex Ferguson accused Manchester City boss Roberto Mancini of "haranguing" the officials after watching Manchester United surrender the initiative with a damaging 1-0 defeat at the Etihad Stadium.

Vincent Kompany nodded home the winner in first-half stoppage time as City leapt to the Barclays Premier League summit on goal difference. But the game was more memorable for a touchline spat between Ferguson and Mancini in the second half, following Nigel de Jong's foul on Danny Welbeck.

At one point, fourth official Mike Jones was stood between the pair, who were eventually pulled away by members of their backroom teams. "He refereed the game," said Ferguson. "He was out on that touchline the whole game haranguing the referee, the fourth official and the linesmen."
