Chelsea manager Jose Mourinho says he has no idea who will replace striker Diego Costa in tomorrow's away game against Newcastle United.
The Spaniard is serving a three-match ban started in mid-week against Walsall.
Loic Remy was on target against the Saddlers and could be the one to lead the offensive department against his old club.
"I don't know, I could tell you I know but I don't," Mourinho told reporters.
"I have to keep analysing the opponent, I have to try to know more about them, who is playing, who is not playing, who is injured, who plays with Coloccini in central defence? Mbemba, Williamson or another one? I have to try to know a bit more to make my decision.
"All of them are good players, we have good strikers.
"Loic wants to play every game, he doesn't want to play against Newcastle because it's Newcastle.
"There is no more motivation for him to score against Newcastle than Walsall. I don't think players think about these things, the motivation for them is to try to play all the time."
