He's in a position where he could dominate the German national team over the next decade, depending on his position," he told the Transfer Talk podcast, per Sky Sports’ website.

"Will he play in the No 10 role and become the new Mesut Ozil or will he settle a bit deeper and become the new Toni Kroos? He's got the ability to play almost anywhere in front of the defence.

"If you look at the unique combination he has of technical ability and eye for a pass, but also having the ability to score and create goals himself, and his runs to be good in the air, I think the best way to sum it up is that he's a cross between Mesut Ozil and Michael Ballack."
