This is the shocking moment a brawl broke out between Manchester United fans at Old Trafford.
The dispute erupted as the Red Devils tumbled to a 2-1 opening day defeat at Brighton.
A video posted to social media showed two men contending in the South Stand as play continued in the background.
Bewildered onlookers tried to interfere by attempting to break up the unsightly melee.
The short clip ended with the two men confronting each other while shouting in front of dozens of supporters.
It is unclear what sparked the dispute between the two.
But neither will have been happy with the end result in the Theater of Dreams.
Erik ten Hag had hoped to celebrate his first-ever Premier League game with a morale-boosting win.
But the day turned into a nightmare for United as two goals from Pascal Gross put Brighton on the road to a historic win at Old Trafford.
Red Devils fans have only just gotten over the 4-0 fill-up in the Amex late last season.

“I think we could have done better with these players.
“I knew it could happen, but I think we should have done better – that’s clear, but I also know it won’t come overnight.”
