Defeats in their final two pre-season matches plus doubts over Diego Costa’s perennial hamstring problems have given José Mourinho a major headache before the first match of their title defence. Having won at Old Trafford on opening day last year, a Swansea side bolstered by the arrival of Ghana forward André Ayew will provide a real test of Chelsea’s readiness for the new campaign.
