Manchester United manager, Ole Gunnar Solskjaer has hailed his side following a Europa League win.
United played 1-0 against Partizan Belgrade with the goal coming from a spot-kick converted by Anthony Martial.
He was later replaced by Marcus Rashford who failed to add to the goal.
Ahead of their trip to Norwich this Sunday, Solskjaer told MUTV: “Second half I thought we dug in really well in the box, defended really well in the box. They played well in the second half and made us defend too deep.
“I’m not happy with the defending at the front. I think that’s been one of our strengths this season but I thought that was non-existent in the second half.
“That needs sorting out because we don’t want to be a team who is just defending in the box.”
