TN's right about Cleverley's position, he had moved into CM by that age. But the others are right that Pearson looks more promising than Cleverley did at that age. Unlike Welbeck, Cleverley never really stood out in our youth and reserve sides. It was only during the loan spells that people with realistic expectations started to think that there might be a place for him in the first team one day.
And it's a reasonable comparison to make, too. As midfielders they are both pass-and-move tempo players, dropping deep to run the play but also willing to move forward with it. They are/were both still very small. Pearson is Cleverley's equal at that age in terms of ball control and short passing, but he just has so much more in his locker. He is the exact opposite of Cleverley in terms of the latter often not imposing himself on a match enough - Pearson is Keane-esque in his attitude. He demands the ball, refuses to be beaten, insists on making a tackle even if he has to run the length of the pitch or make three attempts to do it. He also has a range of passing which Cleverley didn't have at that age, pulling off Carrick-esque diagonals very comfortably. And defensively he is a beast. The 'tigerish' cliche was invented for this kid.
Obviously there is no guarantee that Pearson will ever achieve the first team role that Cleverley has, let alone a more significant one. But it is not 'grass is greener' thinking to say that he is a more promising player than Cleverley was at his age. If anything, it's a grossly hindsight-tinted view that argues otherwise.
