A lipreader has revealed the furious exchange between Manchester United boss Sir Alex Ferguson and Manchester City's Roberto Mancini during Monday's amazing touchline bust-up. The Telegraph says 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 lipreader James Freestone.

Mancini is then seen to mimic Ferguson's 'talking' gesture and then shouts "You can f------ talk" back at the Scot.
