Chelsea interim manager Guus Hiddink says attacking midfielder Eden Hazard will not face Aston Villa this afternoon.
The Belgium international suffered a number of problems so far this season and will again be unavailable as the Blues continue their improbable quest to finish in the Top Four.
A number of key players involved during the international break will be assessed this morning with striker Diego Costa again suspended.
"I will talk to the medical staff today again but [Eden] Hazard is not available for now," Hiddink explained.
"He is on the pitch but with the physios, he is outside the group.
"[Diego] Costa is suspended but he trained very well the past week, he was very ambitious and enjoyed working. He is not injured any more.
"Whether Pato will be actively involved we will see tomorrow. We now have eight games coming up and to be honest there is not much to win for Chelsea any more. I don't give any player a guarantee but there might be some time for experiments.
"His [Pato's] fitness has improved.
"He has worked very hard during the international break. When I started we had just Diego which was one of the reasons we got Pato on loan.
"Meanwhile there was development in, for instance, [Bertrand] Traore, so there was more competition for Pato. Remy has come back after a long-term injury too. I try to make a fair judgement and give opportunities to the others knocking on the door.
"Today Oscar, Traore and Willian came back one day before the game. We will see how they are in their fitness and freshness. After a long journey we will see if they are available tomorrow."
