Mayor of London Sadiq Khan has condemned the ugly scenes which marred West Ham's 3-0 home defeat to Burnley at the London Stadium on Saturday as "disgraceful", his spokesperson said.

The Hammers are facing an investigation by the Football Association after a series of pitch invasions and widespread supporter unrest, which saw the club's co-owner David Sullivan struck by a coin towards the end of the game.

A spokesperson for the Mayor of London said this morning: "The disturbances at the London Stadium were disgraceful and it's clear that there cannot be a repeat of the ugly scenes witnessed on Saturday.

"It is up to West Ham to carry out a thorough investigation, together with stakeholders, and take proper action against those supporters who misbehaved."

Stewarding is overseen externally via the stadium operators E20, and has been a frequent problem for the Hammers since their move from Upton Park.

The latest incidents at the converted Olympic Stadium have raised fears that the club could be punished by having to play a future game behind closed doors.
