With Uruguay Under-20 international Guillermo Varela still to report for duty after his country's World Cup campaign and big-name signings proving hard to pin down, Zaha is the only new face on United's tour of the Far East and Australia.
Signed in January but loaned straight back to Crystal Palace, Zaha has impressed with his direct wing play and is evidently going to provide a threat to Young's first-team berth.
But it is competition Young welcomes and he can see already that Zaha, who made his England debut in Sweden last November, is destined for big things.
"He's going to be a fantastic player," Young told MUTV.
"We wouldn't have signed him if he wasn't going to have a great future and he'll have the experience of listening to the older, experienced players talk.
"It's always good for the club having additions like Wilf and he's been fantastic."
