Gylfi is outstanding, but he does however play the same position as Mata, behind the striker. Maybe he can be deployed in the two man midfield behind Mata, but I'm not sure that would compliment his abilities. And as much as I like my fellow Icelander, he's not as good as Mata (very few are). But he would be more than a welcomed signing, just not quite sure where he fits in our starting XI. For 10m he would be an outstanding squad player, but that would be a waste of talent.
