Chelsea duo Hazard and Costa available to face Arsenal

Chelsea duo Eden Hazard and Diego Costa are fit and available for selection for Sunday's showdown with Arsenal at the Emirates.

Belgium international Hazard could feature for the first time in three weeks after recovering from the groin injury he suffered at Crystal Palace on January 3.

Hazard, 25, has missed he Blues' last three matches and interim manager Guus Hiddink has been careful not to rush him back too soon.

Hiddink, speaking at his pre-match news conference on Friday, said he is not sure if Hazard will be able to feature for 90 minutes against the Premier League leaders but will be in the squad.

Hiddink said: "The last two days he (Hazard) was in full commitment with first-team training, so he is available.

"We have to be careful, because he has fallen into some injuries recently. I'm not sure whether he can play a full 90 minutes yet. We have to consider whether it's best (for him) to start or to come in."

Hazard has struggled with fitness and form this season, and is yet to score for Chelsea during the current campaign.

Striker Costa, who scored last weekend against Everton before coming off injured in the final 10 minutes of the game, is available despite not training much this week.

Hiddink added: "He (Costa) was in yesterday. He was in today. So he will be available as well."

Chelsea go into Sunday's match 14 points off the top four in the Premier League and only four points above the relegation zone.
