Liverpool are one of five teams who are tracking Young Boys centre-back Mohamed Ali Camara, according to TEAMtalk.
The website reports that the Reds, along with Arsenal, Norwich, West Ham and Crystal Palace are all monitoring the Guinean, who is an international teammate of Naby Keita.
Camara has been part of a team that has lost just once in the Swiss Super League this season, with Young Boys having conceded only 23 goals in 31 domestic fixtures.
The Swiss team also had an impressive European campaign, qualifying from their Europe League group and beating Bayer Leverkusen in the last 32 before being knocked out by Ajax.
Whether Liverpool actually need another centre-half, though, it is debatable. The Merseyside club are reportedly poised to snap up Ibrahima Konate from RB Leipzig, while there is growing speculation that the Reds will take up their option to sign Ozan Kabak on a permanent basis from Schalke.
