Chelsea boss Jose Mourinho admits Diego Costa is a slim chance to face Manchester United tomorrow.
Even though Costa has suffered with hamstring issues and spent a night in hospital, Mourinho hopes he can line up against Louis van Gaal's side.
He said: "Diego has a little chance. He's back training individually, but not yet with us (the first team squad).
"Everything has happened to him. He was injured (hamstring) and he had to go to the hospital (before the Maribor game on Tuesday night) with a viral situation that we didn't manage to resolve without being in the hospital over one night.
"The problem that being ill didn't help his recovery process because we didn't want him here. The medical staff went to meet him at his house because we didn't want to bring him here."
