West Ham boss David Moyes has taken aim at Fulham striker Aleksandar Mitrovic for his role in Tomas Soucek's dismissal on Saturday.
Soucek was sent off by referee Mike Dean after accidentally catching Mitrovic with his elbow in Saturday's goalless draw.
Dean went over to the pitchside monitor after consulting VAR Lee Mason and decided the incident merited a straight red.
Moyes was unimpressed by Mitrovic's reaction - the striker went down clutching his face - but says the referees need to be stronger in their decision making.
"I am disappointed with football in general that the officials would allow these situations to take over from the game," he said.
"I can only see the officials being the people that can stop it by not allowing the players to get away with the actions they are taking, because it is making the referee's decision so difficult in giving them a decision when there wasn't one to give."
