Morata showed United what they missed out on when he headed in Cesar Azpilicueta's cross to earn Chelsea all three points.

United appeared set to sign Morata from Real Madrid in the summer before opting for Romelu Lukaku.

Instead it was Chelsea who signed Morata and his first goal in seven appearances was the decider at Stamford Bridge.

This second defeat of the season left United eight points behind leaders Manchester City, while Chelsea stayed fourth but are now just one point behind second-placed United.
