Manchester United rode out a defiant performance from Luton Town to claim a 2-1 win at Kenilworth Road.
Rasmus Hojlund was the hero, striking twice within the first seven minutes to give United a comfortable lead.
However, Carlton Morris pulled one back for the hosts after 14 minutes and Luton went on to pepper Andre Onana's goal with 22 shots, with Ross Barkley hitting the bar with a header in the dying moments.
Hojlund and Kobbie Mainoo were the standout performers for Erik ten Hag's side but it was a far from convincing outing overall.
