Kabak, 20, is a highly-rated central defender and joins Liverpool initially on loan, for a fee believed to be £2.5 million with an option to buy also in the contract, sources have told ESPN.
Jurgen Klopp’s side have moved to sign two central defenders on transfer deadline day with Kabak joining Preston‘s Ben Davies at the Premier League champions.
Liverpool have been linked with several centre-backs in this transfer window as they battled a growing injury list. They are without Virgil van Dijk and Joe Gomez for the rest of the season, while Joel Matip was injured in their win at Tottenham on Jan. 28.
With his options at central defence depleted, Klopp turned to midfielders Jordan Henderson and Fabinho to fill in at centre-back, while youngsters Nathaniel Phillips and Rhys Williams have also stepped into the void.
But with Liverpool defending their Premier League crown and also facing a Champions League round-of-16 clash against RB Leipzig, Klopp has moved to bring in reinforcements.
