Obviously, it's increasingly difficult to comment on Academy players, given we can't see them play live. And, I will make the point that Academy players tend not to be typecast nor shoehorned into a particular position. Indeed, under "previous regimes" there was a deliberate policy of playing them out of position occasionally. To put them under pressure. To see how they cope. To see what they've got. But, yes, Maguire is usually midfield. I saw (past tense) him as a cover a lot of ground, keep the engine running, get the ball, give the ball, drive on midfielder.
Incidentally, I was debating the other day, remote fans will tend to know about those Academy Lads who feature on the highlights reel. The goals. The set pieces. The assists. The Brunts. The Ayaris. Whereas those who were (fucking past tense again) able to watch games live often tend to know more about the midfielders, the wingbacks. The players who have the ball a lot, who the play goes through. Me, personally, over the years, love an Academy midfielder....
