The 23-year-old, who competed in Stuart Pearce's Team GB side at the London Olympics, drifted out of Sir Alex Ferguson's side towards the end of last season due to injury.
Despite a brief setback, the England international has insisted that he is fit to try to help United snatch the title back from rivals Manchester City.
"I've been away for a few weeks now but to come back into a good game in a good stadium and be playing with the world-class players we've got only helps your game, so it's good to be back," Cleverley told MUTV.
"I think the Olympics has been good for me. I've got six games under my belt including the two friendlies so I feel 100%. I'm happy and looking forward to the season."
United begin the new season with an away trip to Everton on August 20.
