According to The Daily Telegraph, German top-flight side Schalke are bracing themselves for a bid from Liverpool for Turkey international centre-back Ozan Kabak in January.
The Anfield giants are light at the back following long-term injuries to centre-back duo Virgil van Dijk and Joe Gomez, while Joel Matip has also struggled to keep fit on a consistent basis.
Schalke are open to selling Kabak for the right price, but they will ask for Belgian striker Divock Origi in part-exchange should an offer arrive.
The 25-year-old is also wanted by Wolverhampton Wanderers in January as they look to land a cover for the injured Raul Jimenez, and Liverpool reportedly value him at around £20 million.
