I think this is a load of rubbish. If anything young players need to be given more of a chance in England. Suggesting they're given too many chances is wide off the mark. Not all young players develop at the same rate. One or two seasons may not be enough. Look at Ramsey, one season after arsenal fans were booing him and wanted him sold he's one of the PLs best players. You don't just get rid. Some players are worth persisting with and you reap the rewards sometimes.
I hope we keep Cleverley. He's a useful squad player and isn't as shit and useless as peoe on here make out.
The thing about Ramsey is that he showed the qualities he's showing now to some degree back in his first couple of years at Arsenal, back at Cardiff, and in his youth and early full international appearances. Had Arsenal gone and sold Ramsey my suspicion is that he'd have performed well enough (to his current standard or close) to make Arsenal regret it, and would have been bought again by a top four side.
In comparison Cleverley has shown nothing to indicate that had he been a 16 year old in the Championship he'd have done anything spectacular or eye catching enough to get a big move. Cleverley could play to his best, and he still wouldn't do what Ramsey does on the pitch. The raw star quality is missing.
If anything Cleverley's more comparable to Henderson. But then even Henderson plays with more confidence in himself, isn't afraid to move with the ball, and has a few more goals and assists in him. I'd take Henderson over him any day. Even in the 2012/13 season I'd have done so.
Like you say he's a useful squad player, playing against the weaker sides when the rest of the team is strong. No need to sell him provided he isn't a reason for us not spending on someone else. Because even if Van Gaal was to trust Cleverley to do the job he requires as a starter, I personally wouldn't. And even if he played to the best of his own ability, I'd always think there was someone else who could do what he does better and more.
So worth keeping, but more as a squad player than as a player to have much hope for as a starter. If he works he way back into the first team after we sign some others, fair enough.
