The Reds' injury problems have seemingly forced Klopp into the market.
Liverpool will attempt to sign a new central-defender during the January transfer window, the Daily Mirror reports, after Martin Skrtel's injury against Watford has left Jurgen Klopp with just two senior options for the foreseeable future.
The Mirror reports that the Slovakian stalwart could miss the next three months of action - although the club are still awaiting the results of the scan.
With Dejan Lovren and Joe Gomez also sidelined, Klopp has just Mamadou Sakho and Kolo Toure to call upon.
While Sakho has established himself as the Reds' strongest option at the back, he made his first appearance in well over a month when he featured against the Hornets at the weekend, and the last thing that the Merseyside outfit need is to lose the Frenchman for an even longer spell.
Meanwhile, there must be serious concerns over whether 34-year-old Toure can handle the demands of the hectic Christmas period, having only made seven appearances in all competitions all season.
As difficult as it can be to sign players of high quality during the January window, it seems imperative to Liverpool's hopes of earning a place in the Premier League's top four that they add a new defender next month.
The Reds are the only side in the top half of the division to boast a negative goal difference, and will certainly need to rectify that if they wish to close the five-point gap to fourth-placed Tottenham.
