Man Utd player ratings vs Arsenal: Matheus Cunha & Bryan Mbeumo's brilliance counts for nothing in agonising defeat as classy David Raya puts inept Altay Bayindir to shame

Altay Bayindir (3/10):

Onana's absence should have given him extra motivation but instead he showed that United need two new goalkeepers, conceding a second goal directly from a corner after a similar mishap at Tottenham last year. And the most frustrating thing about the clanger is he was barely tested otherwise.

Leny Yoro (6/10):

Dealt well with Viktor Gyokeres and kept Gabriel Martinelli quiet. The only criticism was his slow distribution and his reluctance to play long-range passes.

Matthijs de Ligt (7/10):

A typically solid display after missing the back end of last season. Stayed on top of Gyokeres and quickly snuffed out any danger. It was a shame he got so little contact on his effort deep in added time.

Luke Shaw (6/10):

Looked comfortable among the centre-backs, keeping Bukayo Saka shackled for much of the game.

Diogo Dalot (5/10):

Defended well but did not offer enough in attack. It was no great surprise when Amad replaced him in the 55th minute.

Casemiro (6/10):

Had good positional sense and his ability to break up play and then telegraph a pass to Mbeumo sparked one of United's best moves.

Bruno Fernandes (6/10):

Played an inviting pass for Mbeumo but mostly stayed further back in midfield, trying to influence proceedings from deep with mixed results.

Patrick Dorgu (6/10):

Built on his good pre-season campaign with a decent display. Almost levelled with a shot off the post but the less said about his earlier 30-yard effort, the better.

Bryan Mbeumo (7/10):

A very bright debut, getting fans off their seats whenever he charged forward. Demonstrated his pace and power and although he couldn't conjure a goal he has already lit up United's attack.

Mason Mount (6/10):

Playing false nine is not his forte but he worked hard and could be spotted all over the pitch, even at left-back.

Matheus Cunha (7/10):

A classy display, opening up lots of space behind Arsenal's defence. Had one of the best efforts of the game, denied by a finger-tip save from Raya in the first half.

Amad Diallo (6/10):

Gave United an extra edge going forward but failed to trouble Raya with his one effort.

Manuel Ugarte (6/10):

Gave the team an injection of energy although his wayward long-range strike was a waste of a good field position.

Benjamin Sesko (5/10):

Not exactly the debut he would have imagined. A glancing header which went well wide of the target was his only real contribution.

Harry Maguire (N/A):

Thrown on in the 80th minute to cause chaos in attack but didn't manage to unnerve the Gunners.

Ruben Amorim (6/10):

Not starting Amad showed his sense of caution and Mount as a false nine was another surprise which did not really work. He will be encouraged by the performance, however, if not the result.
