The 22-year-old was named in the Olympic squad on Monday.
“I need to hit the ground running for the new season and this is a great chance for me,” said Cleverley.
“The manager [Sir Alex Ferguson] was happy for me that I was shortlisted and had no problems about me being in the Olympics if chosen.
“I will miss United’s pre-season tour and, ideally, I would have liked to do both.
“But after my injury spell out last season, Paul Scholes and Michael Carrick were doing so well I didn’t get much game time.
“So I need minutes on the pitch and I feel that playing in high-stake competitive matches like I’ll get at the Olympics is right for me.
“I am very excited about it and I just want to have a good tournament. It’s a fantastic opportunity and a great boost.”
