David de Gea
Committed his first outright mistake of the season by letting Josip Ilicic's straight shot through him. Could have come off his line for Duvan Zapata's goal. 4
Aaron Wan-Bissaka
Too porous against Zapata for the opening goal and was not anywhere near as proactive in the opponent's half as on Saturday. Regression. 5
Eric Bailly
Bailed out United a couple of times and impressed in only his second appearance of the season. Effectively a one-man defence. 8
Raphael Varane
Came off injured in the first-half. Would be a potential disaster if he is missing for the derby on Saturday. 5
Harry Maguire
Often off the pace and slow to react. Looking to the linesman after Ilicic struck was weak. Shambolic for Zapata's goal and looked to the linesman again. 3
Luke Shaw
Lax when Ilicic made himself available to Zapata to make it 1-0 and did not provide much width for the goalscorers. 5
Scott McTominay
Hit the post with a deflected shot in the fourth minute. Got booked and then continued committing fouls. 5
Paul Pogba
Hardly any strength and unity. No United player needed a performance more than Pogba and he failed to deliver. A disasterclass. 2
Bruno Fernandes
Did little until he broke into the area to latch onto Mason Greenwood's pass and classily backheel for Cristiano Ronaldo. 6
Marcus Rashford
Quiet in the first-half alongside Ronaldo and even quieter in the second. Eventually made way for Edinson Cavani. 4
Cristiano Ronaldo
Set out his stall with a shot in the first minute and equalised clinically just before half-time. Lacked service in the second-half but still pulled United out of the mire. 8
Subs
Mason Greenwood
A magnificent pass for the equaliser and hit the crossbar but was flagged offside. Offered much more than Rashford and teed up Ronaldo. 7
Nemanja Matic
Had little impact. 5
Edinson Cavani
Made himself available. 5
Donny van de Beek
Denied by the 'keeper. 6
Jadon Sancho
Late cameo. 5
Manager
Possibly hasty in abandoning the back three but the bold choice of Greenwood paid off in the short-term and at the death. But United were more vulnerable without a third centre-back. 6
