United's Dutch manager looks set to play with wing-backs and Young has been tried there in pre-season, and he is enjoying it.
The 29-year-old - whose future Old Trafford looked uncertain - is now hoping for a fresh chance under Van Gaal in the new role.
"I’m enjoying playing there,” Young told the Daily Mirror.
“I can play in both wing-back positions and if the manager calls on me to do something I’ve got every confidence in myself to go out there and play well.
"The Inter game was only the second time I had played there, but we go through it in training, it’s a new system and I feel capable of going out there and doing well.
"I’ll have to see how it goes and it’s down to the manager what happens because he picks the team that goes out there.
"But whenever I’m called upon, I’ll give 100 per cent and if I can continue producing performances like the one in Washington, then I can hopefully stay in the team.
"I’ve always been determined to go out and play and I hope I can stay in the team.
"Of course it was disappointment to miss out on the World Cup, but it’s a new season and a new manager has come in.
"Everyone wants to impress him, but the only way you can do that is by training hard and performing on the pitch and that’s what I’ll be looking to do."
