Really pleased for him, the lad just doesn't seem fazed at all. Days like today, academy kid playing against the club's greatest historical rival are what the club is all about and will speed up his maturation curve. Important thing now is to be realistic with our expectations - hoping for a youngster to step up, fully express his range of talents and and perform brilliantly vs Liverpool in his 3rd start as a first team player is a bit unfair. He will take his time, have some teething issues, make a few inexplicable errors along the way, hopefully learn from them, have some patches of poor form but that's all perfectly natural, every footballer goes through that.
The management must now do everything in their means to preserve young Wilson instead of throwing him to the wolves week in and week out, figuratively speaking and that's where Giggsy, who was a prodigy once too comes into the picture. We must be extremely careful with him, Januzaj and McNair (great gesture by Van Gaal TBF with the sub) and bring them along gradually, or risk physical and mental exhaustion because we are not talking about normal circumstances. Playing for an elite side like United or Madrid or Bayern at age 18 or 19, with massive expectation levels and media scrutiny can be extremely daunting and something a lot of us can't relate with, hence the disproportionate criticism.
