West Ham United co-owner David Sullivan has urged fans to "get behind the team".
Last Wednesday's home win against Hull City should have been celebrated by the fans but instead a section rounded on manager Sam Allardyce, booing him at half-time and full-time after a poor display from the team.
Sullivan said: "Everyone should have been happy after that match because the three points were so vital but it was a strange game, some bizarre goals and then the booing at the end.
"We all know the team can play a lot better than they did on that night and everyone was frustrated, the team, the supporters and myself. I know exactly how the fans felt but it is so important they get behind the players.
"There is a perception out there that we are so good under lights but the reality is that, before the win over Hull, our only other floodlit League victory since we took over the club four years ago was Norwich in February."
