West Ham’s London derby with Tottenham has been moved to a Friday night, with a heavy police presence expected over fears rival fans will clash.

The game will now take place on Friday 5^th May and is likely to attract extra security at the London Stadium given the crowd trouble there in derbies earlier in the season.

Chelsea and West Ham fans clashed during October of last year when the Hammers knocked the Blues out of the EFL Cup on a Wednesday night game.

Seven supporters were arrested after fighting broke out in the stands while others were banned for abusive language and throwing missiles.

It was the most severe case of fan violence West Ham experienced at their new home with trouble also against Middlesbrough and Watford as supporters adjusted to their new surroundings.

That sort of trouble has not been seen since but there are fears that it could return for the Friday night game with Spurs – notoriously a volatile fixture anyway.

It will be the first Friday night game at the London Stadium with the game being moved for TV, despite Sky Sports’ poor viewing figures for the time slot so far this season.

May Premier League fixtures moved for TV:

Mon 1: Watford v Liverpool (8pm)

Fri 5: West Ham v Tottenham (8pm)

Sat 6: Manchester City v Crystal Palace (12.30pm)

Sun 7: Liverpool v Southampton (1.30pm)
