Was given little to think about on what was a largely quiet night for the Spaniard, but he spilled a weak shot from Payet to gift Fletcher an easy tap-in for his first ever West Ham goal.
Impressed alongside Jones, where he put in a strong performance and was always on hand to dart out wide to help deal with attempted West Ham counter-attacks.
Had very few problems in the heart of a Manchester United back line that were given little to think about by West Ham’s misfiring front line.
Was given a few things to think about by the marauding Antonio, particularly towards the end of the first half, but largely did well before making way for Blind during the break.
Performed brilliantly over on the right wing, where he defended well and was always on hand to push forward, which he did with great effect.
Gave Jose Mourinho even more reasons to start him on the weekend. Set up Ibrahimovic’s opener with a lovely back-heel before taking advantage of poor West Ham defending to assist Martial’s first goal.
Performed well at the base of the Manchester United midfield, where he constantly snuffed out the danger when his former club tried to break forward.
Marked his return to the starting line-up with two brilliantly finished goals. Always looked dangerous over on the left wing and made plenty of good runs forward.
Made an immediate impact with a well-taken goal with little over a minute on the clock, and from then onwards the Swedish striker made a nuisance of himself in and around the West Ham penalty area before wrapping up the win with one of the final kicks of the game.
Looked bright in his number 10 role. Played an important role in his side’s first goal of the evening and put in a determined shift from then onwards.
Was well beaten by four great goals, but the Spaniard nonetheless pulled off several good saves to make sure that his side didn’t lose by an even heavier margin.
Started well over on the left flank and was involved in a good battle with Valencia before being forced off due to injury just before half-time.
Didn’t look entirely comfortable, despite putting in a few good tackles. Struggled to deal with Ibrahimovic and was given the runaround by the Swedish striker.
It wasn’t a great night for the Italian, who was beaten far too easily on a few occasions and sometimes allowed himself to be dragged out of position.
Arguably West Ham's best defender. Put in a determined defensive display and was often his side's saviour.
Made a few good runs forward in advanced positions, but he largely struggled to make an impact before missing several good chances late on.
Drifted in and out of the game. Largely did well in the first half but faded away in the second half as Manchester United started to dominate even more.
Set up Fletcher’s goal after his long-range shot was fumbled by De Gea and impressed with some of his set-pieces, but the Frenchman was sloppy in the build-up to Manchester United’s second goal and was largely to blame.
Largely pressed well in the middle of the pitch, but on a few occasions he was defensively careless and left behind pockets of space that were exploited by the Manchester United forward line.
Got forward well during the first half but was far too sloppy defensively, which was evident in the build-up to Manchester United’s opener when he completely lost Ibrahimovic.
The youngster will never forget this evening after scoring his first senior goal for West Ham against the club that decided to let him go.
Came on for Shaw at half-time and continued the left-back's good work with a determined and resolute performance.
Made his return to the Manchester United side after eight months away and looked bright during his short cameo, resulting in him playing an important role in his side's final goal.
Only featured for the final few minutes after replacing Mkhitaryan but nonetheless did well during his short time on the pitch.
Replaced the injured Cresswell and largely got forward well but was caught on the break defensively.
Featured for the final half an hour after replacing Antonio and largely did well, although he was unable to make much of an impact going forward.
Came on with 15 minutes to play as he tried to get his side back into the game, but he was poor in front of goal and sent a few good chances well wide.
