Players and staff from Manchester United and Manchester City had a scuffle following Sunday's derby near their dressing rooms.

Up to 20 players and staff were engaged in the brawl that led police officers and stewards to separate the two teams.

Mikel Arteta, one of Pep Guardiola's assistants, had blood streaming down his face.

Jose Mourinho reportedly told City to keep their music down and became engaged in a row with Ederson. Mourinho and Ederson shouted insults to each other in Portuguese before Mourinho reverted back to English.

Romelu Lukaku was said to be prominently involved as the confrontation escalated into something much more serious, described by one person on the scene as being reminiscent of a pub fight.

Mourinho was struck by a plastic bottle and squirted with milk.
