I don't particularly like United and Fergie isn't exactly the nicest of blokes, but he is one of the greatest managers of all time. Robbie is obviously a very good talent, but the fact that Fergie didn't put up too much of a fight to keep him would be a concern. He had Cleverley on loan for a few years at various clubs, but he seemed to always believe that he had a future at OT. He obviously didn't think the same of Robbie.
Every time, I've seen Robbie he's looked very good, but there's a world of a difference between being good against Oman or Derby County and then being able to turn it on against Sweden away or Chelsea. I'm not sure he's going to be the next world class prodigy that we crave, but I do think that he can be a good, maybe very good premiership player.
