West Ham manager David Moyes called for the club's fans to get behind the team after ugly scenes marred Saturday's 3-0 Premier League loss to Burnley.
Tensions reached boiling point at the London Stadium as some fans invaded the pitch during the game, while others in the stands vented their anger at chairmen David Gold and David Sullivan .
Captain Mark Noble shoved a pitch invader to the ground, while defender James Collins also confronted fans who approached West Ham players during the dreadful defeat to the Clarets.
Meanwhile, fans gathered below the directors' box chanting 'sack the board' as the atmosphere grew increasingly toxic.

Speaking about the scenes, Moyes told Sky Sports: "We want the supporters behind us, but you can't cross the line and come onto the pitch.
"I don't think I've been at football games in my time where I've seen that.
“All I'll say to all of them is that we need them.
“We're fighting for points. We're all in it. The players know we did well today for long periods. We didn't do so well for a couple of minutes in the second half.
“We needed the supporters with us in a different way.
"All I ask for is that everybody sticks together and we try to get ourselves enough points to make sure we're a Premier League team (next season)."
