Maguire was jeered by Leicester City fans throughout United's 1-0 win at Old Trafford yesterday, but the £80million centre back responded with a fine performance to help his side to a second clean sheet of the season.
"You know, I think the manager's said about him, he talks non-stop, he's a real leader and he can play as well," said Young.
"The style of play we use, we use the centre-halves a lot to play out from the back and everybody has got confidence in him. And everybody has confidence in Victor [Lindelof], Jonah [Phil Jones], Marcos [Rojo] - all the defenders, all the centre-backs can go in there and do the job.
"Again he showed today what a man he is, and I think as a backline we played a really good game."
