Ole Gunnar Solskjaer was delighted with Axel Tuanzebe's performance against PSG.
The young defender was excellent in the absence of captain Harry Maguire as United pulled off a deserved 2-1 victory in France.
Speaking after the game, Solskjaer said: "When you go away to a team like this against Neymar and Mbappe you have to defend well and your keeper will have to make saves. Axel Tuanzebe is a top defender and his first game in 10 months was testament to the quality he has.
"Bruno missed two penalties in a row but he's not going to stop taking them - he showed focus and character.
"We know we need 10 points to get through so next week's game is very important. There are so many games."
