David de Gea
Started nervously by failing to come off his line, hit the stands and almost botched a goal kick. 5
Victor Lindelof
Inexplicably started at right-back and the experiment was not remotely vindicated. Atletico were at their most menacing down Lindelof's side. 4
Raphael Varane
Whistled pre-match and Varane was not blameless for United's sloppy first-half. Shored up in the second but a night to forget. 5
Harry Maguire
On his heels when Joao Felix was on his toes for the opening goal, fabulous cross and header though they were. Better after the break. 5
Luke Shaw
No visible impact at either end and his form is not anywhere near at a level that suggests he is still an automatic pick. 5
Fred
Relocated to the base of midfield and was often swamped in a loose area. Predictably regressed when he has performed well further forward. 4
Paul Pogba
Dithered on the ball too much and failed to reach the heights of friend Geoffrey Kondogbia, who ran the midfield. Hooked again. 3
Bruno Fernandes
Sloppy with the ball and became increasingly narked, which worsened matters. Did not lack for effort and found Elanga for the equaliser. 6
Marcus Rashford
An unexpected inclusion and back on the right, where Rashford dislikes playing. Tried but failed to have an impact and resorted to selfishness. 3
Jadon Sancho
Hard-working enough but most of his urgent running was in the wrong direction. Struggled for space on either flank. 5
Cristiano Ronaldo
Starved of service, became frustrated and never looked like regaining his composure or scoring against a team he plundered two knockout hat-tricks against in the past. 4
Subs
Aaron Wan-Bissaka
Created an opening. 6
Alex Telles
Offered energy. 6
Nemanja Matic
Brought balance to midfield. 7
Anthony Elanga
Equalised brilliantly. 8
Jesse Lingard
Hardly saw the ball but shot on target. 6
Manager
The right-back experiment patently did not work and he selected too loose a midfield, mistakes he effectively acknowledged with a triple change that was belated. Again, though, his changes made a difference. 6
