He doesn't seem fast/dynamic enough to maintain as a RW player in comparison to guys like Deulofeu or Adama. I think he should/will move to attacking midfield and learn how to weave around in buildup like Iniesta, he seems to have that ability to create space with his dribbling and movement plus the added bonus of a great shot.
Looking at this game comp, he plays deep, roams often, and his mentality doesn't seem to be that of an attacker really. Silva is a good comparison but we don't really want a Silva on our RW do we? He's an attacking midfielder in style and most of his ability will be nurtured in that area. Nevertheless, great signing and it's all but official at this point.
