Jose Mourinho has admitted that he does not know whether Diego Costa will return to action for Chelsea's trip to Leicester City.
The striker, who has scored 19 goals this season, has been sidelined for the team's last three matches due to a hamstring injury.
Costa could be missing again for the Blues on Wednesday when they travel to the King Power Stadium, though there is a chance that he will be back in the squad.
Chelsea are just two wins away from being crowned champions following Sunday's goalless draw away to London rivals Arsenal.
