Sam Allardyce: West Ham United boss bemoans bad decisions

West Ham United manager Sam Allardyce says his team have dropped points this season because of mistakes by officials.

Speaking before his team take on Manchester United this Sunday, Allardyce said West Ham were denied a draw when Kevin Nolan's equaliser was ruled out at Old Trafford in September.

Allardyce is not the first manager to criticise officials this season - Jose Mourinho was recently fined £25,000 for comments about referees.
