The midfielder was part of the Team GB squad which reached the quarter-finals at the Olympics, but he is now back with United ahead of the start of the Premier League campaign.
He made his first appearance of pre-season on Saturday when he started the 4-3 win over Hannover and he was pleased to be involved with his club again.
“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 per cent. I’m happy and looking forward to the season.”
United assistant boss Mike Phelan praised Cleverley’s performance against Hannover, with the game also seeing the return of Team GB captain Ryan Giggs.
Phelan said: “I thought Tom looked very, very sharp. He’s played quite a few games for the GB team so he’s probably ahead of schedule in some respects.
“Ryan probably needs to feel his way through it a little bit more, but Tom played a very, very good game for us.”
In the first month of last season before he got done at Bolton, I thought that Cleverley was brilliant and United were scoring goals for fun. We never quite looked as fluid and as good after that. Hopefully Cleverley can stay fit this season, and answer the critics that say that United need to spend big on a central midfielder.
