Radek Vitek
A good performance was overshadowed by an error for the Forest goal. 5
Marc Jurado
Supplemented the attacks well and played some dangerous balls in behind the lines. 6
Rhys Bennett
A real captain's performance. A big goal in a big game and defended superbly. 8

Louis Jackson
Dealt with the Forest threat well and coped with the overall occasion well. A mature performance. 6
Sam Murray
Great delivery for the opening goal and some combative tackles throughout the match. 7
Kobbie Mainoo
Dazzled the Forest defence with his dribbling ability and won back possession a few times. Showed both silk and steel on the biggest night of his career so far. 8
Dan Gore
Super recovery tackle early on and offered plenty of energy in the middle of the pitch. Rallied the Old Trafford crowd late on to get his side over the line. 7
Isak Hansen
Drew a few fouls with clever runs including the free-kick for the opening goal. 6
Alejandro Garnacho
The star of this side. He had a quiet game until he won the controversial penalty out of nowhere and scored it with ease. The performance warranted his Cristiano Ronaldo celebration. His fitness levels proved crucial again with a stellar second. 8
Sam Mather
Lively whenever he got on the ball. He did plenty of the dirty work, which allowed his teammates to shine. 6
Charlie McNeill
Signs of promise, but hardly got into the game against a stubborn opposition defence. 6
Subs
Maximillian Oyedele
His introduction helped swing the game in United's favour. Offered plenty of energy and composure at a key time. 6
Joe Hugill
Fantastic pressing in the build-up to the penalty. Usually judged on his goals, but he sacrificed himself for the team. 7
Sonny Aljofree
Not enough time on the pitch. N/A.
