Chelsea boss Jose Mourinho feels Diego Costa is getting back to his best.
Diego Costa played the full 90 minutes against Sporting CP after Mourinho suggested he needed to work on his sharpness following the Newcastle loss.
Mourinho thought Costa's performance was "very good", adding: "He wants to improve his condition.
"The confidence is not high, his condition is not the best. (But) he always wanted the ball, always wanted to associate with the wingers and with Fabregas.
"Very important for him. Better than against Newcastle, better than against Sunderland."
