Sakho was unable to hold down a regular first-team spot for the Ligue 1 champions last season, and was frequently rotated by Carlo Ancelotti.

Liverpool have a paucity of defensive options, and though Brendan Rodgers brought in Kolo Toure on a free, the futures of Martin Skrtel and Sebastian Coates remain uncertain.

Skrtel has been linked with a move for Napoli, as Rafa Benitez is keen to substantially invest in players in the summer.

PSG are believed to be keen to retain Sakho's services and have already offered him a two-year contract rise along with a pay rise.

Liverpool could step up their interest as they appear to have reached a dead end with Sporting Lisbon's Tiago Ilori.
