West Ham United boss Alan Curbishley has had a pop at tomorrow's opponents Chelsea over their treatment of match officials.

Curbishley criticised the so-called big four's attempts to influence referees, days after Chelsea were charged with failing to control their players during the 2-0 victory away to Derby. The club has also only just paid a £30,000 fine for threatening behaviour towards the referee Mike Dean during the defeat at Old Trafford.

"The big four teams definitely get after the ref a bit more than other teams," Curbishley said. "All the top teams are that way inclined - decisions are disputed, especially when they're at home."
