The Red Devils won two successive league matches prior to this, and a third across all competitions, but Wolves played superbly to stun the hosts.
Brazilian midfielder Fred scored after Paul Pogba teed him up, and he shot a right-footed effort low into the bottom corner. For the visitors, Joao Moutinho finished off a clever counter-attack with a decent strike from edge of the box.
Here are the player ratings of United as Mourinho’s side failed to do well:
David de Gea: 8
Another superb show by the Spaniard. He made two stunning saves in the first half to deny Wolves. Couldn’t do anything for the goal conceded. Denied Adama Traore for the winner.
Antonio Valencia: 6
Was defensively alert and solid, but the Ecuadorian didn’t provide much going forward.
Chris Smalling: 6
Well drilled and disciplined show by the central defender in the 1st half. Got caught out for the equaliser.
Victor Lindelof: 4
Looked shaky to start with, and was vulnerable to threats many a times.
Luke Shaw: 4
Not the kind of performance we have seen from him so far. Didn’t do enough to stop the cross that led to the goal.
Marouane Fellaini: 7
Did well once again as a cover for the defence behind him. Was dependable, and played to his strengths. Had a glorious chance to score.
Paul Pogba: 7
Was superb at times with his ambition. Fed an excellent ball to Fred, and also put in some delightful balls in the box.
Started off a bit shaky, but the goal eased him down. Also took a brilliant free-kick, only to be denied.
Jesse Lingard: 5
Gave his all and ran all around to try and make an impact. Needed to do better with his crossing.
Alexis Sanchez: 3
A sorry afternoon for the Chilean. Didn’t put in the work from the left and lacked the cutting edge.
Romelu Lukaku: 4
Was isolated throughout, and there was lack of support.
Anthony Martial: 5
Came in and brought in the energy. Looked to find Lingard in the box.
Juan Mata: 3
Failed to clear the defenders with his crosses.
Andreas Pereira: 4
Lacked the cutting edge and was too ambitious. Wasted the free-kicks as well.
