David de Gea
Made a fine save from Theo Walcott when he palmed his header over the crossbar and he denied Walcott a second time in the second half. 7
Aaron Wan-Bissaka
Limited in attack once again and got caught out once by Kamaldeen Sulemana but did brilliantly to clear off his own goal line. 6
Raphael Varane
Made a big block in the first half and ended the half with a good chance where he failed to beat Gavin Bazunu. 7

Lisandro Martinez
Booked for a cynical foul on Carlos Alcaraz but, like against Crystal Palace, improved when United were reduced to 10 men. 8
Luke Shaw
United's best attacker in the first half and he whipped in a couple of inviting crosses. Teed up Bruno Fernandes to hit the post and defended ably. 8
Casemiro
Bustled about the pitch but his tackle on Alcaraz was overzealous and invited trouble. It came when the VAR effectively recommended a red card. 5
Bruno Fernandes
Relocated to central midfield and breached the Southampton defence to play Marcus Rashford in for a great chance and his shot was tipped onto the post by Bazunu. 6
Antony
Too one-dimensional and Southampton often read Antony's intention to cut inside and he was sacrificed for a more direct winger. 5
Jadon Sancho
Played one fine pass to Rashford, who miscontrolled. Sancho drifted to the right too often when he was supposed to play centrally. 5
Marcus Rashford
Squandered two presentable chances before Casemiro came off and he was vulnerable against Kyle Walker-Peters when Southampton attacked. Also dived. 5
Wout Weghorst
Wasted a good headed chance when it was 11 versus 11. Hooked for Scott McTominay after Casemiro was sent off. 4
Subs
Scott McTominay
Positionally disciplined. 6
Alejandro Garnacho
Had plenty of the ball but did little with it and was substituted after injury. 4
Facundo Pellistri
Had another positive impact. 6
Fred
No time to have an impact. N/A
Harry Maguire
No time to have an impact. N/A
Manager
Took a needless chance with United's midfield selection against accomplished midfielders and United struggled for balance after the first substitution. 5
