USArsenal that kind of growth spurt can be disruptive. If he were to grow to 6"3 or 6"4, it likely means adjusting the way he has played so far in his young career as he gets used to his bigger frame. Might make him more prone to injury earlier on, so Arteta needs to judge this one carefully in his usage. If he does reach that size, I imagine he will eventually shift to become a more central player than stay out as a winger.
