David de Gea
Both of his posts and crossbar were struck by Brighton until he was mischievously beaten by Neal Maupay's penalty. Still hasn't officially saved a penalty since April 2016. Big late save. 6
Aaron Wan-Bissaka
Awful at both ends and his dismal use of the ball eventually led to Brighton winning a penalty. Did not look fully fit. 3
Victor Lindelof
Made some key interceptions early on but was put under pressure by Brighton's pressing pair of Aaron Connolly and Maupay. 5
Harry Maguire
Equalised just before half-time to salvage United's horrendous half and set them on their way to victory but United were porous in both halves. Won late penalty. 7
Luke Shaw
Was not offering enough until he won the free-kick from which United levelled. His forages bought United time and set-pieces. 6
Nemanja Matic
Off the pace and was cautioned before his adroit lay-off enabled Maguire to make it 1-1 just before half-time. Much improved in the second-half. 6
Paul Pogba
Not at the races again and his selection was dubious. Rightly reprieved by the Video Assistant Referee but came off just after the hour mark. 4
Bruno Fernandes
Was booked and gave away a penalty but then had key contributions for Maguire's and Rashford's goals. His moments salvaged another poor United performance. Scored the winner. 8
Mason Greenwood
Had the ball in the net but Marcus Rashford had drifted offside. Got into spaces but could have used the ball quicker. 5
Marcus Rashford
Was often going through the motions and his dawdling saw him caught offside on two occasions United had the ball in the net. Atoned with a fabulous solo goal. 7
Anthony Martial
Produced United's best piece of play in the first-half but otherwise far too quiet and uninvolved again. 5
Subs
Fred
Did not do much wrong. 6
Eric Bailly
Came on to shore things up. 5
Donny van de Beek
Late cameo. N/A
Manager
Ole Gunnar Solskjaer
Reverting to the 'first XI' of June and July reinforced the feeling United have stood still. Was negative with his substitutions and invited pressure. 5
