Shocking video shows Man United fans fighting each other during defeat to Brighton

The clip shows some supporters clashing with each other as fans looked on in horror.

Two fans got into a scuffle, with another person seemingly attempting to diffuse the situation.

They trailed two-nil at the break, with his side failing to overturn the result in the second-half - pulling just one goal back.

Ten Hag slammed his team's performance and called the defeat a 'setback' as he made his feelings known in his post-match interview.

"Of course, definitely a setback and real disappointment," he told Sky Sports.

"I knew from the start it would not be easy. We gave two easy balls away and it was not good in the organisation.

"It is clear to see the second half we were better in midfield with Eriksen down and Ronaldo up. We created and Rashford had two good chances, it is a shame we did not score.

"I am not satisfied, totally not. We lost and it was not necessary. We should do better.

"We made mistakes on the ball and organisation mistakes in defending. We have to take the lessons and learn quickly from it.

"Brighton are a decent team, all the compliments, but I look to my team and we should not give two easy goals away."

Ten Hag takes charge of his second Premier League game next Saturday when his side travel to Brentford.
