He does quite well in the air for his size, whatever that is, he's better than a lot who are much bigger than him and he doesn't seem to get knocked off the ball too often. For the first time in a while he started to get games more regularly and his performances were good after a run of games so I really don't see any negatives at all about this if we sign him.
I hope that he plays every game next season because if he does it will be because he's earned his place, Rafa will only play who he's comfortable playing on merit, other than Colback who was given far too many games.
