Guus Hiddink says Chelsea must accept Diego Costa's style of play but insists he should not be considered an "idiot" on the pitch.

Costa will miss Saturday's Premier League clash with West Ham after being sent off in last weekend's FA Cup quarter-final defeat to Everton at Goodison Park.

The striker escaped punishment over an alleged gesture made to supporters as he left the pitch but could still face further suspension after being charged with improper conduct for his reaction to his dismissal.

But when asked at Friday's media conference if he should accept that Costa is "a bit of an idiot" during matches, Hiddink replied: "It's too strong. If you know the definition of an idiot it's different to him. He has to play as he does, we have to accept that.

"He desperately likes to play. He accepts that he is suspended but he's not happy with it.

"Everyone wanted to be on his case. It's a matter of temperament and character."

Costa was omitted from the Spain squad for their upcoming friendly matches but Hiddink confirmed that was due to a minor hip injury.

"It was a medical issue also by the Spanish coaches and medical team. He has a little problem in the tendon in his hip," he said, adding that Eden Hazard will also sit out the international break with a similar problem.
