Alejandro Garnacho, who wasn't used in the win at Burnley on Saturday, opened the scoring with a controlled finish, before Casemiro doubled the lead before the break with a powerful header.
Anthony Martial added a third in the second half with well-taken half-volley to put the result beyond any doubt.
The likes of Harry Maguire, Facundo Pellistri, Mason Mount and Sofyan Amrabat all looked bright during the time they were on the pitch, but it was our second goalscorer and assister of the third strike who emerged at the top of our Man of the Match poll with a convincing 64 per cent of the vote.
