David de Gea
Fine save from Rodrigo de Paul at 0-0 and was beaten at his near post by Renan Lodi for the winning goal. 6
Diogo Dalot
Adventurous in attack but asleep at the back to let Lodi score and failed to regain the confidence he played with prior to then. 4
Raphael Varane
Read the game well amid Harry Maguire's sloppiness and was unfortunate to be denied by Jan Oblak from a free-kick. 7

Harry Maguire
Some clumsy moments in both boxes and awkward in possession. The crowd almost turned against him. When he was substituted, several did. 4
Alex Telles
Started by default in the absence of Luke Shaw. Never on the same wavelength as Jadon Sancho and porous in his own third. 4
Scott McTominay
Another performance where he did not lack commitment but did lack quality against superior midfielders. 4
Fred
Brimming with confidence after his performance against Tottenham and he transmitted it to the first-half. Quieter in the second. 6
Anthony Elanga
Should have scored with a point-blank chance and went down easily to gift Atletico possession they profited from. 5
Bruno Fernandes
Lacked sharpness and became easily agitated by the referee. Rightly substituted for the final quarter of the match. 5
Jadon Sancho
His poorest performance for a while, particularly as he was up against an auxiliary right-back in Marco Llorente. 4
Cristiano Ronaldo
Understandably committed and eager but had no joy against Atletico's obdurate defence almost all of the night. 5
Subs
Paul Pogba
Little impact. 5
Marcus Rashford
Toiled. 4
Nemanja Matic
Brought expertise. 5
Edinson Cavani
Next to no service. 4
Juan Mata
No impact. 5
Manager
Refusing to consider Pogba as a starter off the left was a mistake and McTominay's instant recall was not vindicated. Made proactive changes but should have made some earlier. 5
