"Everyone is asking about Kai Havertz," the Leverkusen No2 told talkSPORT. "If you see him play, it tells you everything.
"For me, he has the elegance of Zidane. If you see his movement, he's very elegant, he's always calm, he has great passing ability.
"What a lot of people don't see, because we watch him every day, is that he's pretty fast. That's a big bonus.
"He's a great player; he's scoring goals, he's great in the air and he's pretty fast. It's up to him how far he can go.
"I can't say he will be the best German player ever, but he has the talent and there are no limits. He's displaying signs of Zidane."
