Liverpool are monitoring PSG's Mamadou Sakho's situation, as the centre half stalls over a new deal, the Daily Express reports.

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.
