Tottenham Hotspur are reportedly considering a summer move for Freiburg's Robin Koch.
The centre-back has featured on 33 occasions for his German club during the 2019-20 campaign, while he has contributed one goal in 31 Bundesliga appearances this term.
Koch's contract with Christian Streich's side is due to expire next summer, though, and it is understood that he is not prepared to sign an extension.
According to Bild, Tottenham are keeping a close eye on developments and have identified the 23-year-old as a potential replacement for Juan Foyth, who is expected to move on this summer.
Koch joined Freiburg from Kaiserslautern in the summer of 2017 and has made 86 appearances for his current side in all competitions, while he has also been capped on two occasions by Germany.
