Man Utd fans brawl in stands on embarrassing opening day defeat (VIDEO)

The Red Devils were beaten 2-1 at home by Brighton in the Premier League

Some Manchester United fans suffered a miserable day on and off the pitch on Sunday as fighting broke out among their number in the stands at Old Trafford.

In what was new coach Erik ten Hag's debut in the Premier League, the Red Devils went 2-0 behind to Brighton in the first half on the opening day of the season thanks to a brace from Pascal Gross.

United eventually lost 2-1 after failing to capitalize on an Alexis Mac Allister own goal which had given them hope in the second half. 

With stress and tension high across a fan base used to glory, but which has not seen its team lift a piece of silverware in five years, a fight broke out in one of the stands at the 'Theatre of Dreams'.

Videos and photos that have circulated on social media show two men in an heated exchange and pushing one another.

In one snap, one of the men also appears to have his hand around the throat of his rival.
