Chelsea have set their asking price for Bertrand Traore.
After an impressive season on-loan with Ajax, Traore is attracting interest from across Europe.
BILD says Chelsea are prepared to sell and have informed Schalke, which are among the chasing pack, they can sign the Burkina Faso striker for €15 million.
S04 chief Christian Heidel and coach Markus Weinzierl are meeting this week to thrash out their summer market plans, with Traore high on the agenda.
Lyon are also interested in the pacy attacker, who has stated hopes of establishing himself at Chelsea next season.
