Liverpool are expected to bolster their backline this month after being dealt a defensive injury crisis in the first half of the campaign.
The Premier League champions have often been left short of options at the back this season, with Virgil van Dijk and Joe Gomez both facing a battle to play again this season after picking up serious knee injuries towards the end of 2020.
Trent Alexander-Arnold, Andy Robertson and Kostas Tsimikas have also suffered with niggling problems of their own, meaning Jurgen Klopp has been forced to deploy a number of makeshift back fours.
But with the January transfer window now open, Liverpool are being tipped to get their chequebook out and strengthen Klopp’s defence - with five players already on their radar.
It is believed Carmo, who has racked up 12 appearances for the Portuguese outfit this season, could be available for less than his £36million release clause.
The Reds are reportedly in talks with Lille over a potential deal for Botman, who has put together a string of impressive displays since joining Lille from Ajax in July.
Turkish journalist Ekrem Konur claims the French club are demanding £18million for their central defender’s services.
Reports in Football Italia suggest the 23-year-old Torino centre-back is on Liverpool’s defensive shortlist, although Merseyside rivals Everton are also circling.
Bremer has made 12 appearances for the struggling Serie A outfit this term.
Roma’s 22-year-old defender, who is capable of operating at both centre-half and left-back, is another target for Klopp and co.
However, Calciomercato claim Arsenal are likely to provide competition after launching an enquiry about the youngster.

According to reports in Portugal, Liverpool have seen a £20million bid rejected for Mendes - who can play at both left-back and centre-half.
The 18-year-old is widely considered one of the brightest young talents in Europe, nonetheless, meaning Real Madrid are also understood to be interested.
