Video footage has emerged which shows West Ham United and Tottenham Hotspur fans clash on the London Stadium concourse.
West Ham beat their bitter rivals Tottenham once again thanks to a goal from Michail Antonio.
Antonio pounced to fire home from an Aaron Cresswell corner as David Moyes’s side moved up to fourth place in the table.
There is no love lost between West Ham and Tottenham.
And several videos have emerged on social media and on WhatsApp of clashes between Spurs and Hammers supporters on the London Stadium concourse.
The rival fans broke through a dividing door and a large-scale scuffle ensued with drinks being thrown between the West Ham and Tottenham supporters.
Footage from the away section of the concourse shows Spurs fans kicking open the dividing door.
Stewards were pushed aside and no police can be seen in the video as West Ham fans responded.
It comes after West Ham issued a warning to fans about behaviour ahead of the game.
The Hammers were hit with a £50,000 fine by UEFA after crowd trouble on the terraces during the win over Rapid Wien last month.
It is not clear whether anyone was hurt in the incident. But it appears from the video that the worst anyone would have got was wet.
West Ham and Spurs are yet to comment.
It brings back memories of some of the first games to be held at the London Stadium where stewarding and segregation arrangements were criticised.
Stewarding is not the responsibility of West Ham on a matchday but the LS operators.
