Hoffenheim chief Alexander Rosen says they're prepared to sell David Raum this summer.
The left-back has been linked with Liverpool this past week.
Rosen said, "It would not be a simple €50m trade. Although that alone would be insane for a player who came from the second division on a free transfer.
"We are in the driver's seat in that sense."
Raum has a contract with TSG to 2026.
