Haven't watched Bremen much this season so I can't answer the second part, but in the few matches I have watched him with Werder, they made the mistake of playing him behind the striker. Marko is a winger, and pretty darn good one. He is faster than any of our current players, and his small stature gives great ball control, so you'd back him in any one-on-one situation. Even with the German national team, he has impressed quite a bit everytime he played, and that, imo, is saying something.
