David de Gea
His kicking was suspect again a day before the Spain squad is announced but he made an important save from Juanmi. 7
Aaron Wan-Bissaka
Energetic and ran into space further afield but his use of the ball was poor and the momentum he had has subsided. 6
Harry Maguire
Defended decently on his first European start since September. Should have scored with a header from a corner in the second half. 7

Lisandro Martinez
Defended well all night and was not at all fazed by the partisan atmosphere. His inclusion amid the rotation reinforced Martinez's importance. 7
Tyrell Malacia
Had a panicky first half in a raucous atmosphere but, like most of his teammates, improved in the second with a comeback beyond Betis. 6
Casemiro
Had a slow start but then managed the game better than most teammates and it was his pass that led to Marcus Rashford's goal. 7
Fred
Energetic but not particularly effective in the final third. Came off on the hour to be saved for Sunday's FA Cup quarter-final. 6
Facundo Pellistri
Embarked on a couple of early dashes that United did not make the most of and his bright start in the second half led to Rashford's first chance. 6
Bruno Fernandes
His temper almost got the better of him on one occasion and he was nowhere near as influential as in the first leg. But he avoided a booking and a suspension. 6
Marcus Rashford
Had a sloppy 55 minutes and wasted two easy one-on-ones in the two minutes before he scored superbly to make it 1-0. 7
Wout Weghorst
Another poor night on his 17th successive start, he was unreliable holding up the ball and he hit the post from close range. 4
Subs
Jadon Sancho
Still dawdles on the ball too often. 5
Marcel Sabitzer
Had a shot saved. 6
Anthony Elanga
No obvious impact. 5
Victor Lindelof
Came on to give Martinez a rest. 6
Diogo Dalot
Had a good crossing chance. 6
Manager
Sensibly rotated with Fulham on Sunday the bigger game. United didn't perform in the first half but kept a clean sheet, which killed any hope Betis had of recovering. 6
