When he first came out in the public eye (when he was 18) it looked like he would be one of the best full backs in the world, because he was such a complete player for that age. The hype died a bit, but I think he will be a good player, could probably reach the level of Lichtsteiner very soon. He is quite fast (not as Licht), solid in defence, but he has a better cross then Licht.
