Manchester United No2 Mike Phelan admits their US tour could unearth a young bolter for the senior squad.
United are preparing for their opening game against Kansas City Wizards.
Phelan told manutd.com: "For some players pre-season can be a major, major step for them. For some, it's part of the journey to getting fit, for others it might be their one big chance to impress. But that's the nature of being at United. We have to look to the future and give young players exposure to play on the big stage. We can then make judgements on where we want them to be and how to use them in the season."
