The youngster was sidelined for a substantial part of last season through injury but started both the Carling Cup ties at Leeds and Aldershot and also came on as a late substitute in the Champions League win over Otelul Galati.
Ahead of another likely appearance against Crystal Palace at Old Trafford, the 19-year-old is delighted with his progress.
"I must admit I didn’t think the first-team games would come as soon as they did," he said in an exclusive interview with United Review, the official matchday programme for the quarter-final. "At the start of the season, a lot of the young guys start talking about loans and most people want to land themselves a loan deal to get more experience.
"Nothing worked out on that front for me, so I just concentrated on training well and getting my fitness levels up with the Reserves. Then the Carling Cup game at Leeds came along and it was an amazing experience.
"And to come on at Old Trafford in a Champions League game was out of this world. It all felt a bit unreal. That's the most excited I've ever been and I just want to keep experiencing things like that."
Fryers has already played in the heart of the defence and at left-back for Sir Alex's side so he gives the boss a couple of options going into the Palace tie.
"I was a bit surprised the opportunity came along so soon, especially because I’ve had a couple of injuries in recent years," he added.
