Harry Maguire was at the heart of the chaos as Manchester United's FA Cup clash with Arsenal descended into an on-pitch brawl at the Emirates.
Tempers reached boiling point between the historic rivals when the referee pointed to the spot with twenty minutes to play, calling for a foul after Maguire caught Kai Havertz in the box.
This decision was not taken to kindly by the Man United centre-back, who pleaded his innocence with the referee and appeared to accuse Havertz of diving.
With no VAR at the referee's disposal in the third round FA Cup encounter, the penalty was not overturned, sparking all hell to break loose between the players.
