Speaking to BILD, Gnabry said: "He has enormous potential and is one of the best players in the world right now. I don't know where his limit is!
"Michael can achieve anything. He can play centrally, keep the ball, and is a good one-on-one player. I didn't know him that well and didn't expect it to be like this. Maybe it doesn't seem that way sometimes, given the way he presents himself, but he has a very good mindset. Michael works hard, he's a very good boy, very determined. That's why I think he still has a lot of potential."
