He showreel of very good goals I saw the other day - to remind myself there IS a very good player in there! - exclusively involve him starting from either the middle or right of the box. Not one clip shows him coming from the left hand side.
Will wait until we actually see him played in the position he was very good in for Alkmaar. No idea how good he is until then, being played as a defensive Left-sided midfielder. Hard to judge him when he's not getting to use pretty much any of the attributes we bought him for.
Very tidy player with great technique. Hasn't impacted games as much as we would like him to so far, however I have seen enough to believe he may yet come good.
