Jose Mourinho’s return to Stamford Bridge ended in defeat following Alvaro Morata’s second-half header and he is definitely not happy about that.
Morata’s brilliantly-taken header in the 55th minute was the difference on another frustrating trip to London for United, with six of their last seven away defeats coming in the capital.
United pressed for an equaliser, with Mourinho throwing all his attacking options on from the bench.
But they did not test Thibaut Courtois enough in the Chelsea goal, mustering just two shot on target in the whole match.
