Liverpool have allegedly contacted the representatives of Tottenham Hotspur's Davinson Sanchez to express an interest in signing the central defender.
The Premier League champions have lost both Virgil van Dijk and Joe Gomez to long-term knee injuries, meaning that a new centre-back is expected to arrive at Anfield during the January transfer window.
A recent report claimed that the Reds had identified RB Leipzig's Dayot Upamecano as their leading target, but the likes of Manchester City and Manchester United are also said to be in the hunt for the Frenchman.
According to reports in Spain, Liverpool are also keen on Sanchez and have already made contact with the Colombia international to register their interest.
The 24-year-old has made 126 appearances for Spurs since arriving from Ajax in 2017 but has largely struggled to hold down a starting role on a consistent basis.
The South American, who has a contract at the Tottenham Hotspur Stadium until June 2024, has not even made the squad for his team's last three Premier League matches.
Jose Mourinho's side are thought to value the defender in the region of €60m (£54m).
