According to Sky Germany reporter Dennis Bayer, Mainz have set their stall out for teams interested in Jonathan Burkardt.
The club’s leading goal-scorer has been valued at €35 to 40million should a someone look to buy the 24-year-old.
As a result, the package would be too expensive for Eintracht Frankfurt, Bayer Leverkusen and Bayern Munich – all of whom showed interest.
Even some Premier League sides could be deterred by such a figure therefore his future remains open.
Burkardt has been on fire this campaign with 15 Bundesliga goals to his name just behind Patrik Schick (17) and Harry Kane (23).
