Touchline bust-up revealed
Manchester United's manager Sir Alex Ferguson and Manchester City's manager Roberto Mancini (right) confront each other on the touchline
Ferguson and Mancini had to be separated during an explosive finger-jabbing confrontation in the 76th minute of a highly charged encounter at Eastlands which saw City take control of the title race with a 1-0 victory.
Ferguson had leapt from his dugout to protest after an ugly challenge from Nigel De Jong on United substitute Danny Welbeck.
Ferguson was seen to gesture at Mancini and shouted "I've f------ had enough of this..." according to lip-reader James Freestone.
Mancini is then seen to mimic Ferguson's 'talking' gesture and then shouts "You can f------ talk" back at the United manager.
The pair shook hands at the end of the match and Mancini tried to play the incident down afterwards, though Ferguson blamed his Italian counterpart for the confrontation, accusing Mancini of harassing officials throughout the match.
"Mancini was badgering the ref and the fourth official all game. He was complaining about refs all week, but he can't complain about this one," said the Scotsman.
Ferguson, though, had few complaints about a defeat and he admitted had left the destiny of the title in City's hands.
“We didn't test their keeper enough really, we started brightly and for the first 15 minutes we dominated, but the longer the half went on we were looking for half-time and the goal came at a bad time for us," Ferguson said.
"I can't complain about the result, they were more of a threat from counter-attacks.
"It was a damaging result, they are in the driving seat and we are up against it. They only need to win to two more games and they win the league, simple as that," said Ferguson, whose side have now taken only four points from a possible 12 in their last four games.
