Bayer Leverkusen coach Peter Bosz admits they face losing Kai Havertz at the end of this season.

The young Germany attacker is being tracked by the likes of Liverpool, Manchester City, Bayern Munich and Real Madrid.

Bosz told AD: “In Germany they see him as a child prodigy. He is from Aachen, has been playing here since he was eight. Nice boy to work with. Intelligent. He also plays the piano.

“We sold his buddy Julian Brandt to Borussia Dortmund last summer. Havertz suddenly became even more the eye-catcher.

“During the winter break, we showed him clips that he was not getting into the sixteen (yard box) enough. Now he does that more often. His share of goals and assists skyrockets. He can't be held next summer. That will be a transfer of one hundred million. What am I saying: more than a hundred million."
