You only have to rewind 2 years to remind yourself of what people were saying about Cleverley(then look at him now) for you to remember to stop making declarations already. This place can be so weird(stupid) sometimes.
To be fair, I doubt a 15 year old Cleverley was being chased by all of Europe's elite. Pereira was always on a different trajectory.
I can see him being involved from now on. He played very well on Tuesday, and LVG has spoken many times about age does not matter in his 'philosophy'.
To be honest, we used to think the same way. United fans (not you) often tend to be a bit hypocritical, at least in recent years with regards to youth. Players now are always 'not ready' to play, and the approach seems to be more cautious than before, although we love to brag that we basically invented giving youth a chance.
I am all for caution, but if the players in the first-team are crap, and that is exactly what most of them are in midfield - then the kids should play. Take away Mike Oliver and 75,000, put Fletcher, Cleverley, Pereira and a football in a park and I'm pretty confident who will come out looking the best footballer. Now he just needs a bit of trusting here and there.
