The game was a 3-0 defeat for West Ham, but the issues in the crowd were a much bigger talking point.
There was an incident where a West Ham fan got onto the pitch, and got into a confrontation with captain Mark Noble.
West Ham are attempting to suggest they are not responsible for the stewarding at the stadium, but that is not going to be a creditable defense with the FA. West Ham are responsible for how their fans behave, and some punishment is a near certainty.
Anything from playing behind closed doors to lifetime bans for supporters is on the table.
