"He had two or three really good moments, as you do when you're young," Solskjaer said. "You don't run the game as a first performance for a 19-year-old.
"But he got the crowd going, and has shown one or two glimpses of what he can do, he has in training anyway. And the game wasn't won, it was 2-0 and was still go out there and perform. It's not like it was 4-0 and it's just a party, so he did well defensively as well and I think he'll remember this for a long, long time."
He added: "The pleasing thing is we're through and another clean sheet, 2-0 flatters us a bit because I think they played some great stuff, but then again we could have had three or four towards the end. The second goal was excellent with Alexis [Sanchez] getting Romelu [Lukaku] in, so individual quality managed to get us through, to be fair."
