Schalke chief Rouven Schröder admits they're seeking to sell Ozan Kabak this summer.
After spending the second-half of last season on-loan with Liverpool, Kabak is attracting interest from Leicester City and Newcastle United.
Schroder said, "Ozan is positioned in the player market in such a way that I believe that the transfer can also work in a timely manner.
"We can assume, whatever his own aspiration and goal, that he will face greater challenges."
Liverpool passed on their permanent option for Kabak at the end of last season.
