David de Gea
His kicking was dismal but when the unmarked Jakub Moder headed at goal De Gea was at his optimum again with a super save. 8
Diogo Dalot
Did little wrong but also did little right on his eighth successive start. His attacking impact could be better but Dalot's defending has improved. 6
Victor Lindelof
A late inclusion at the expense of the unwell Raphael Varane and performed respectably in his first game in four weeks. 6
Harry Maguire
Sloppy with his distribution at times and if there was a centre-back on the front foot it was Lindelof. Helped United keep a clean sheet. 6
Luke Shaw
So lax he was scolded by some supporters for not taking a throw-in urgently enough and was booked for a cynical foul on Tariq Lamptey. 6
Scott McTominay
Somewhat fortunate to start again and he struggled to impose himself against Yves Bissouma in the first-half but robbed him of the ball for Cristiano Ronaldo's goal. 6
Fred
A rusty return from the Brazilian, whose inability to keep the ball represented a downgrade on the benched Paul Pogba. Made way for Pogba. 4
Bruno Fernandes
Seemed to spend most of the first-half either feigning agony or berating the referee. Stepped it up in the second and somehow didn't score until added time. 7
Anthony Elanga
Caught on his heels too often and is another right-footed United forward who struggles on the right wing. On his toes to seize on Lewis Dunk's mistake and get him dismissed. 6
Jadon Sancho
Had a good chance early on but should have played it to Fernandes or Ronaldo. Another decent evening for in the in-form winger. 7
Cristiano Ronaldo
Started well, engineering an opening for Sancho and took his goal magnificently to lift the mood. Should have scored more. 8
Subs
Paul Pogba
An upgrade on Fred. 7
Marcus Rashford
Worried Brighton's defenders. 6
Alex Telles
Indecisive. 5
Manager
Freshened the team up and although the first-half was poor and the game changed through Ronaldo's brilliance and the red card, United played fluently with the extra man. 7
