I need to watch him, and the Bundesliga in general. I don't wanna rely on the old misleading YouTube videos.
But I did indeed watch one of those videos, and this guy looks absolutely class from that. Very fast, fantastic right foot both when dribbling and passing - can play through balls along the floor or crosses, high square balls etc. His shooting looks really good too - he's very good at picking out the corners with the inside of his foot. In one compilation I watched he was taking free-kicks and corners too so a set piece specialist.
He looks a very big talent and at 25 should be entering his prime now - let's hope he can maintain this level when he leaves Frankfurt. It will be interesting to watch him develop.
