Cobham - Jose Mourinho is confident Diego Costa will recover from his latest hamstring injury in time to feature in the final three weeks of Chelsea's Premier League run-in.
The Spain international, the English top-flight's joint leading scorer so far this term with 19 goals, has been ruled out of league leaders Chelsea's short trip to west London rivals QPR on Sunday.
His absence comes after he managed just ten minutes in last weekend's victory over Stoke City, having come on as a half-time substitute.
