Andre Onana was Manchester United's hero on a night Old Trafford paid tribute to Sir Bobby Charlton.

Fans were left frustrated by the first half which ended 13 seconds early when the referee blew up, prompting some boos from the crowd.

Erik ten Hag made a number of substitutions early in the second half and substitute Christian Eriksen helped create the breakthrough with a lovely cross for Harry Maguire to head in but there was late drama when Scott McTominay conceded a penalty in the final seconds of injury time. But Andre Onana came to the rescue, saving the penalty from Jordan Larsson. Our chief United writer Samuel Luckhurst was in the pressbox to cover the game and here are his player ratings.

Diogo Dalot

Another sloppy performance going forward that was not salvaged by a goal on this occasion. Disciplined in defence. 6

Harry Maguire

Erred in the build-up for Diogo Goncalves's shot that hit the post but recovered for an otherwise steady performance defensively and his headed goal was superbly placed. 8

Raphael Varane

Off the pace on his first start in three weeks in the first half but Copenhagen did not capitalise and Varane settled into the flow of the game come the second half. 6

Sergio Reguilon

Did okay on his return after a month but missed a clear breakaway pass. Came off just after the hour. 6

Sofyan Amrabat

Plodded through the first half and his consistently poor form in the league and Europe continued. Substituted at half-time. 4

Scott McTominay

Played higher up amid his goalscoring form but United struggled to provide opportunities in an anaemic first half. Improved next to Christian Eriksen but rashly conceded a stoppage-time penalty. 5

Antony

He has started six times now this season and performed poorly in all of them. Not up to it again. Made way early in the second half. 4

Bruno Fernandes

The introduction of Eriksen buoyed the captain and he played Alejandro Garnacho through for a one-on-one the Argentine squandered. 5

Marcus Rashford

The longest he has stayed on the pitch for a while. He created a good opening for Rasmus Hojlund but spurned a one-on-one and shifted to the right. 5

Rasmus Hojlund

Tried his heart out, as always, and his lay-off for Christian Eriksen almost gave United the breakthrough. A third goalless game, though. 6

Subs

Christian Eriksen

Made a huge difference. Close to scoring shortly after his emergence, played fine passes and crossed for the goal. 8

Alejandro Garnacho

Alert on the ball, as ever, but marred his performance by overhitting the ball when one-on-one. 6

Victor Lindelof

Steady. 6

Anthony Martial

Got minutes. 5

Manager

Got it wrong overlooking Eriksen and then got it right by introducing him at half-time. United were unrecognisable in the second half. 6
