Liverpool have completed the six-month loan signing Ozan Kabak from Schalke.
The deadline-day deal was made possible when Shkodran Mustafi terminated his contract with Arsenal to join the German side, enabling Liverpool to push through their own move for the Turkey international.
Kabak had been strongly recommended to Jurgen Klopp by his best friend David Wagner, who managed him at the Veltins-Arena.
Former Schalke sporting director Christian Heidel, who worked with the Liverpool boss at Mainz, also provided a glowing appraisal of the youngster.
