The 21-year-old, who has made four appearances for the Red Devils this season, admits it will be difficult to challenge for Joe Hart's England place in the near future and says he would relish the opportunity to represent Great Britain.
He told United's official website: "With Joe Hart doing so well in the England team, potentially a candidate for the next captain of the team, chances might be few and far between in the future so the Olympics is a good opportunity to represent not just England but Great Britain at such a big event."
With Anders Lindegaard and David de Gea injured last week for the visit of Stoke City to Old Trafford, Amos was handed his Premier League debut by manager Sir Alex Ferguson.
He said: "It was really good. I'd been waiting a long time to play in the Premier League - I had played first-team games before but it was kind of a big milestone I guess."
The youngster also revealed that he wanted to leave the club on loan earlier this campaign, adding: "I've been trying to stay patient all season and have been dying to get out on loan at times. Everything happens for a reason so probably a good job I didn't go out."
