Starting XI
Tom Heaton: Beaten by the early goal and unusually hesitant given experience. Had settled but replaced three minutes into second half after appearing to hurt his hamstring. 6.
Noussair Mazraoui (off 46): Showed lots of energy starting at right-back on his World Cup return. Overlapping runs helped United's forwards even if he didn't get the ball so often. 7.
Ayden Heaven (off 46): Rightly booked for a thudding late challenge on Khvicha Kvaratskhelia after being beaten to the ball by Ibrahim Mbaye for the opener, although he had no cover. 6.
Harry Maguire: Eye-catching pivot on the edge of his own area that drew an appreciative response from the Manchester United fans behind that goal. Also pushed forward and had a shot later on. Clearly a crowd favourite. 8.
Luke Shaw (off 64): Quiet game, although that was a positive. Fortunate to concede a corner rather than threaten his own goal with a sliced first-half clearance and took a heavy knock in the second half. Was running OK when he came off. 7.
Andrey Santos (off 64): Extended in a way he hasn't been so far in his Manchester United career but another effective display. Does the simple things well. Close range header just over from a Harry Maguire nod-back and got forward more when Mount went off. 8.
Mason Mount (off 18): Took a pretty hefty blow to his ankle in a midfield challenge. Didn't stay down but in obvious discomfort. Michael Carrick immediately sent Tyler Fletcher to warm-up and made the change soon afterwards. 6.
Amad Diallo (off 64): Quiet until an excellent challenge on 16-year-old Axel Koukaba allowed him to win possession in the PSG half. Aware enough to set up Bryan Mbuemo rather than go on his own. A repeated threat after that. 8.
Shea Lacey: Started in number 10 role once more and probably didn't get on the ball as much as he wanted. Kept his shape but not quite the same fluency as in previous games. 6.
Patrick Dorgu (off 64): Busy enough but the end product wasn't there. Needs to be more effective in dangerous positions. 6.
Bryan Mbeumo (off 64): Looping header over the bar and curled free-kick just wide. Well-taken 32nd minute leveller after being set up by Amad Diallo and then went close in the second-half. United's biggest threat. 9.
