David de Gea 6
A mistake for Sunderland's winner, and not the first of its kind. He was unfortunate that the ball bounced off him to go back over the line, but the mistake was that he was again unable to deal with a shot that is close to his body as well as he dealt with shots further away from him. The opener wasn't a terrible mistake, either, but it was nevertheless an error. Between those saves were some impressive stops, though.
Matteo Darmian 6
Decent positioning, in attack and defence, but he still cannot cross, to the point there is no point him trying if he's just going to lose possession with it every time. He looks far less panicked than he has in the past, and is getting used to the league. He should be of use to Jose Mourinho.
Cameron Borthwick-Jackson 6
A few pointless crosses of his own, but he also had a couple of more dangerous efforts from the left. Not the attacking threat that Luke Shaw is, but certainly seems a smarter player generally.
Chris Smalling 5
Didn't bother marking Lamine Kone for the winner, yet again proving he's not up to the job unless he radically improves, or United markedly lower their expectations for the latter. Sadly, that seems the most likely of the two options.
Daley Blind 6
Fine. A six-out-of-10 player if ever there was one. In fact, he made one important intervention to stop Jermain Defoe scoring at the near post.
Morgan Schneiderlin 5
Michael Carrick 5
Toilet when passing.
Juan Mata 6
There was no point him being there. There was no point United being there at all, to be honest, under Louis van Gaal. His shot set up the goal, and he's more threatening than on the wing, but that's still not enough for him to convince Mourinho, certainly.
Anthony Martial 6
Showed plenty of experience, and some wastefulness on the wing, but the coolness of his finish cannot be overstated. Far better he is given more chances in front of goal and less work to do to set up others.
Jesse Lingard 5
His pace is important on the right wing for the balance of the side, but the team will benefit from a more accomplished player next year,
Wayne Rooney 6
He ran around shouting a lot. Not back to his worst by any means, though. Perhaps, like the rest of the side, he can no longer fight for the side if things are even vaguely tough. He and the rest of his team mates should enjoy the next few matches.
Terrible, but not so terrible he should be forbidden from having a birthday.
Good name, good performance. Another player who deserves another chance, but mainly because the rest of the squad has underperformed so consistently.
As someone on Twitter pointed out - if he'd come on for Preston North End at that stage, they'd have expected nothing, too.
