Chelsea interim manager Guus Hiddink says attacking midfielder Eden Hazard could feature against Arsenal on Sunday.
The Belgium international last featured for the Blues on January 3 against Crystal Palace.
But he is expected to be involved with striker Diego Costa also expected to be in the starting line-up at the Emirates Stadium.
"He [Eden Hazard] was well prepared by the physios until two days ago when he started participating in training," Hiddink explained.
"Today and yesterday he was in full commitment with first team training so he is available. I am not sure whether he can play a full 90 minutes yet so we have to consider in the upcoming hours whether he will start or come on.
"We will decide on game day.
"[Diego Costa did] not [train] much, but he was in yesterday and in today and he will be available as well.
"On the experience of this season, especially the last games, he is of big worth for us. I like him to be focused on that. The focus is on what he is good at and he is doing that.
"As I have said before I cannot guarantee anything as we are not dealing with machines, we are dealing with human beings. When he is focusing on what he is good at around the box he is of big worth."
