Liverpool have set their demands for Montpellier target Loris Karius.
The German goalkeeper has returned to Anfield after a two-year loan spell with Besiktas.
Hertha Berlin have also been linked with Karius, but it is the Ligue 1 club who are the frontrunners to win his signature.
And Goal says Michel Der Zakarian's side will have to pay 6m for the 26-year-old.
Karius still has two years remaining on his contract and has stated he will not leave the club unless guaranteed playing time.
