Hiddink: Costa Still Unhappy  (Sky Sports)

Guus Hiddink says striker Diego Costa has accepted his suspension after his red card in the FA Cup defeat at Everton, but remains unhappy about the whole affair.

The striker was shown the first red card of his Chelsea career after picking up a second booking in the 84th minute for a clash with Gareth Barry, ruling him out of this weekend's game against West Ham United.

Hiddink, who will also be without the injured Eden Hazard at Stamford Bridge on Saturday, said: "Of course, he was not happy and we will see if he gets the other game as well but, yeah, he was not happy with that.

"We will see if it is going to a third game, yes or no. What can I say? He desperately likes to play, of course, and he accepts he is suspended - but he's not happy with that."

The Chelsea interim boss says he has not had to speak to Costa about his future conduct despite his often confrontational approach.

Hiddink added: "He has not been warned by board members. I talked to him and we talked many times about him playing on the edge and his reactions.

"We were happy and are still happy with his performances but I told him he has to control himself. Of course, he knows, he knows.

"It's a matter of temperament and character. If he reduces what he did more frequently in the past, we are progressing and we have to have hope."

On Hazard, Hiddink added: "Eden has discomfort in a tendon in the muscle from his upper thigh. It will be good for him to rest. When he starts in the Euro (2016 finals in June) it will be with better physical fitness."

With Radamel Falcao, Loic Remy and Alexandre Pato working their way back to full fitness, Hiddink has challenged his three back-up strikers to prove they are worthy of selection.

"Falcao has had a very difficult time with injury," said the Dutchman. "He has recovered... he has been training for 10 days with the first team.

"When we signed Pato (in January) we had a very difficult situation, the only competitive striker we had was Costa. We had Remy in troubled water.

"Falcao also, we have to see after the international break if he is fully competitive. We have to wait to see how he reacts to the more intensive training he is undergoing. Everyone is getting fitter, that is the law of competition."
