CHAOS broke out in the Old Trafford stands during Manchester United's 2-1 win over Rangers in the Europa League last night.

The madness came after large groups of Rangers fans appeared to have managed to buy tickets to the game inside the home end at the Theatre of Dreams.

Officially, Rangers had brought a traveling support of 3,000 to Manchester, however, video footage from the game appears to show that there were many more fans dotted around the stands.

Clips filmed inside the home end show brawls breaking out as Man Utd supporters appeared to confront alleged Rangers fans inside the home end.

The videos show fans throwing punches and pushing other supporters out of their seats and towards the concourse.

Stewards can also be seen trying to diffuse the situation and prevent mass fighting from breaking out.

Fans online claimed that they saw "glass bottles" being thrown between the supporters after Rangers fans had been identified in the home end.

Others also claimed to have seen young children in tears.

The Manchester Evening News has detailed a statement from Man Utd regarding the huge number of Rangers fans found amongst the home fans.

It read: "In anticipation of the risks around tonight’s game, we took the strictest possible measures to prevent sales to away fans in home areas.
