Chelsea boss Jose Mourinho says midfielder Ramires will only be back after the international break.
The 27-year-old is still out with an abductor muscle injury and will miss tomorrow's home game against Aston Villa but striker Diego Costa is expected to be in the regular line-up.
"Ramires [is out]. Everybody else is good," Mourinho told reporters on Friday.
"It's a muscular injury, he won't be able to play on Tuesday [against Sporting Lisbon] or even against Arsenal.
"He needs the two-week international break [to recover], maybe he will be back after that.
"Diego [Costa] plays tomorrow and starts without problems. The question is always the same; can he finish the game and be in condition to play in Lisbon 48 hours later?
"I don't know but at the moment I'm not thinking about Sporting or the Champions League, I'm thinking about Aston Villa and the Premier League.
"He plays for sure, he starts the game for sure and he's in a very good condition to start."
