David de Gea
Slow in getting down to Moises Caicedo's shot and his afternoon got worse thereafter. Let down by a hopeless defence. 4
Diogo Dalot
Performed inoffensively in the first-half but was the opposite in the second, culpable for goals two and three. 3
Victor Lindelof
Hesitated in the move for the first goal and a defender who struggles against pace and power was outpaced and outpowered. 2

Raphael Varane
Let off by Danny Welbeck in the first-half but Brighton were merciless in the second. His lack of resistance for Pascal Gross's goal was shameful. 2
Alex Telles
He has been starting by default for a while and should not start again. Dreadful from start to finish and repeatedly targeted. 2
Scott McTominay
Mystifying he emerged for the second-half. Bossed by Yves Bissouma and Moises Caicedo and confirmed it with his constant fouling. 2
Nemanja Matic
Was often a one-man midfield due to McTominay's struggles but did his utmost to calm proceedings. Was harshly hooked at half-time. 5
Anthony Elanga
Overwhelmed by Brighton's intensity and struggled to do anything right. Substituted at half-time. 2
Juan Mata
At an away ground and an against an intense team, he showed why he is a specialist in certain situations. The game passed him by. 3
Bruno Fernandes
By the time he tested Robert Sanchez, the game was over and United were a lost cause. Another ineffective performance. 3
Cristiano Ronaldo
Ropey from the off with his passing and his shooting was wayward. Harshly booked but never looked a threat. 2
Subs
Fred
Brought some energy and at least cared. 5
Edinson Cavani
Did plenty of running and had a goal disallowed for offside. 5
Harry Maguire
United didn't concede with him on the pitch and he came close to scoring. 6
Manager
Unsurprisingly named an unchanged side and could not legislate for the gutlessness of some players. His substitutions had no impact. 4
