Bayer Leverkusen accept they face losing Kai Havertz at the end of the season.

Sport1 says Bayer believe they can raise €100m from the 20 year-old's sale.

A raft of Europe's biggest clubs are in contact with Bayer about a deal for Havertz.

Bayern Munich, Barcelona, Real Madrid, Manchester City, Chelsea, Manchester United, Liverpool and Arsenal have all been mentioned as suitors.

Bayer are basing their asking price on the €120m paid by Atletico Madrid for former Benfica whiz Joao Felix.
