Hertha Berlin are reportedly weighing up a summer move for Liverpool goalkeeper Loris Karius.
The 26-year-old has been on loan with Besiktas for the last two seasons, making 67 appearances in all competitions for the Turkish giants.
As it stands, the German will return to Anfield this summer, but a recent report claimed that the stopper had pleaded with his parent club to allow him to join Besiktas on a free transfer ahead of next season.
West Ham United have also been credited with an interest in the former Manchester City youngster.
However, according to Sport1, Hertha Berlin are now keeping a close eye on developments as they consider an approach during this summer's transfer window.
Karius, whose contract at Anfield will expire next summer, has made 49 appearances for Liverpool in all competitions, including 33 outings during the 2017-18 campaign.
