"We won't wind up Chelsea's Diego Costa", Says Allardyce

Chelsea take on West Ham in the premiership game today and manager Sam Allardyce has told reporters his players will stay well clear of Diego Costa.
It seems that Diego Costa does not go longer than a game without getting into some sort of dispute with an opposing player and Allardyce thinks it motivates him.
"I think trying to wind him up only makes him better, which is a silly thing to do! He will take a bit of shackling. We can’t get involved with him. I’ve told our central defenders not to get involved with the fact he might try and upset them."
Chelsea go into the game on the back of winning the Carling Cup but West Ham have not won in six games.
