What do you mean?
I mean he's a youth goalkeeper who very few people will have any reasonably informed view on whether he's remotely half-decent, and loads of players who appear decent at youth level ultimately fail to make it at a senior level anyway.
So bringing in Lopez, who has already played in la Liga and been in the Spain squad despite only being 21 and for just €6m seems potentially like a great deal. Whereas, for the reasons mentioned above, McGee might well never make it and we have no reason to believe that he will make it - he also turns 21 in a couple weeks and I dont believe has played senior football yet. So I dont see why we should care whether the Lopez signing impacts him. From a lot of the youth reports, Glover (still 18) is the better prospect anyway isnt he?
