All of Europe's top teams are chasing Kai Havertz but no decision has yet been made on his future, says Bayer Leverkusen director of sport Simon Rolfes.
The 20-year-old forward is expected to leave the Bundesliga club at the end of the campaign after another outstanding season.
The Germany international has been linked with Real Madrid, Bayern Munich, Manchester United and Chelsea, having contributed 11 goals and five assists in 26 games this season.
