The Reds have spent the final days of the transfer window making enquiries about a number of centre-backs, including Torino’s Gleison Bremer, Marseille’s Duje Caleta-Car and Braga’s David Carmo.
But their search eventually landed on Kabak, whose departure from Schalke was contingent on the ailing Bundesliga club signing a replacement.
The 20-year-old underwent medical checks in Gelsenkirchen earlier on Monday, and approaching the German transfer deadline it has been widely reported that a deal has now been agreed with Schalke.
According to multiple reporters, Liverpool have negotiated an initial half-season loan, paying up to £1.5 million for this part of the deal, with a further fee of £18 million securing Kabak’s permanent signing in the summer.
Crucially, the Reds have an option to buy, not an obligation, which allows Jurgen Klopp to assess the player before sanctioning his addition on a long-term basis.
He won’t be the only centre-back to join the Reds on deadline day, with Ben Davies also due to arrive from Preston in a deal worth up to £1.6 million.
