Bayer Leverkusen boss Peter Bosz is full of praise for Juventus defender Matthijs de Ligt ahead of their Champions League tie.
Bosz coached De Ligt at Ajax.
“When I was coaching Ajax he was only 17, but he was a great player even then," Bosz said.
“There are only a few talents like him around. Juve are a great team, who are difficult to face.
“Sarri loves to get his teams playing well. We've already seen it with Napoli and Chelsea."
