Jose Mourinho was involved in a furious dressing-room bust-up with Manchester City goalkeeper Ederson as the Manchester derby descended into acrimony.

Sources claimed the Manchester United manager had milk and water thrown at him after the spat with Ederson.

Mourinho was thought to have gone to the door of City’s dressing room to ask their players to show more respect amid apparent disappointment over the way the Premier League leaders were celebrating their 2-1 win, as music blared from the visiting team dressing room.

But a war of words ended up breaking out at that point with Mourinho and Ederson believed to have been yelling at each other in Portuguese as a melee ensued involving players from both sides. There were even reports that Mourinho was hit on the head with a plastic water bottle, with security staff eventually forced to intervene.

The former Everton and Arsenal midfielder, Mikel Arteta, one of Pep Guardiola’s assistants, was left with blood running down his face after allegedly being cut above the eyebrow in the skirmishes, which evoked memories of the infamous Battle of the Buffet at Old Trafford in October 2004 when Sir Alex Ferguson was hit by pizza after United’s game with Arsenal turned ugly.
