Liverpool have reportedly asked Hoffenheim to name their price for highly-rated young defender Niklas Sule.
Despite already recruiting Schalke defender Joel Matip for next season, Jurgen Klopp is still believed to be targeting centre-backs as he bids to bolster his back-line.
And Klopp has identified the Germany Under-21 defender as a potential summer signing, according to German paper, Bild.
Sule, 20, played alongside Roberto Firmino for two seasons in the Bundesliga and he could convince the youngster that Merseyside would be a good move.
The German youth international is 6’4″ and is believed to be a towering presence in the air.
