Liverpool have reportedly enquired about the availability of Sporting Lisbon defender Goncalo Inacio.
The Reds can currently call upon the likes of Virgil van Dijk, Ibrahima Konate, Joel Matip and Joe Gomez as their centre-back options.
Following an underwhelming 2022-23 campaign which will end without a trophy, Liverpool could look to strengthen their backline ahead of next season.
The Merseyside club have seemingly identified Inacio as a potential target for the upcoming summer transfer window.
According to Le Parisien, Liverpool have already held talks to establish the feasibility of a summer transfer for the 21-year-old.
The young centre-back is highly regarded at Sporting, where he has risen through the youth ranks to establish himself as a first-team player.
Inacio has made 118 appearances across all competitions for the Portuguese giants, chipping in with 10 goals and eight assists.
Sporting are not prepared to let Inacio leave for anything less than the €45m (£40m) release clause that is in his contract.
Paris Saint-Germain director Luis Campos has been keeping tabs on Inacio, and the French giants could provide Liverpool with competition for his signature.
A recent report also claimed that Manchester United are showing an interest, with a number of their current defensive options expected to leave this summer.
After falling down the pecking order following Lisandro Martinez's arrival last summer, Harry Maguire and Victor Lindelof could look to find regular playing time elsewhere.
Axel Tuanzebe and Phil Jones will leave on free transfers at the end of the season, while Eric Bailly is set to depart when he returns from a loan spell with Marseille.
Liverpool, meanwhile, beat Brentford 1-0 on Saturday to record a sixth consecutive victory that leaves them in fifth position and one point adrift of fourth-placed Man United, who have two games in hand.
