Having been replaced as the Reds' first-choice goalkeeper by Alisson Becker following a nightmare display in the 2018 Champions League final, the 26-year-old went to play for the Istanbul giants.

Karius has had a topsy-turvy time in Turkey and recently reportedly filed a complaint to FIFA over unpaid wages, with the German goalkeeper now calling a premature end to his two-year loan deal.

"Hi everyone, today I terminated my contract with Besiktas," he wrote on Instagram.

"It's a shame it comes to an end like this, but you should know that I have tried everything to solve this situation without any problems. Unfortunately, they haven't tried to solve this situational problem and even refused my suggestion to help by taking a pay cut".
