Cleverley and Danny Welbeck were both sent out on loan last term by Sir Alex Ferguson to improve their Premier League experience, while Chris Smalling, having been signed for £10m from Fulham, made an unexpected impressive impact in his first season at Old Trafford.
"I think all three of us can be quite happy with the campaigns we have had," Cleverley told the Manchester Evening News. "Chris has had a fantastic first season and proved his worth in the centre of defence. Danny went to Sunderland and has shown that he can score goals at that level.
"I played 25 games for Wigan and had some unforgettable experiences. I think we've all been successful and learnt a lot.
"From my own point of view, to have an end of season like we did at Wigan when we escaped from relegation with two victories in the last two matches, was unbelievable. I will remember that for the rest of my life.
"The whole thing was a brilliant experience that has helped me no end. Tactically, I couldn't have worked under a better boss than Roberto Martinez.
"I always felt I could play at the top level but now I know what it takes and I feel ready for it more than ever with United.
"All I want now is to win this tournament with England and then I will be flying into next season."
