Manchester United boss Jose Mourinho was reportedly unhappy with how loud Manchester City’s squad were playing their music before a brawl broke out following Sunday afternoon’s derby.

Goals from David Silva and Nicolas Otamendi opened up an 11-point gap at the top of the Premier League table, but much of the talk in the aftermath of the clash surrounded events in the tunnel.

Reports suggest Mourinho had water and milk poured over him and was hit in the head by a bottle after confronting City’s players over the volume of their music while they celebrated in the dressing room.

An independent witness near the changing room told The Daily Mirror that they had never heard music played so loud before.

The FA have launched an inquiry into what exactly occurred in the tunnel, with both United and City blaming each other for sparking the brawl.
