Liverpool will reportedly move for Paris Saint-Germain defender Mamadou Sakho, should they fail to land Gary Cahill in the summer.
Cahill is seemingly set to be the the centre of a bidding war when the transfer window reopens after the Daily Mail reported that the Reds, Arsenal and Manchester City are seriously considering making offers.
However, the Mirror claims that Liverpool will turn their attentions to Sakho if they miss out on 25-year-old Cahill - with Bolton allegedly wanting around £20 million to secure his services.
A versatile defender, able to operate either in the middle or on the left, Sakho is understood to have impressed Liverpool director of football Damien Comolli with some imperious displays, and has now gone on to become a full France international.
The imposing 21-year-old has also previously been linked with Arsenal, who too could join Liverpool in pursuit of the PSG man should Cahill stay put.
Despite having the the likes of Jamie Carragher, Martin Skrtel and Daniel Agger at his disposal, Kenny Dalglish is said to be keen to bring defensive reinforcements to Anfield - should he be awarded full-time manager's post.
Also on the Liverpool shopping list are more potent wide options, as well someone to provide cover for Andy Carroll and Luis Suarez, and - with a hefty transfer kitty expected to be at Dalglish's disposal - it looks set to be a busy summer at Anfield.
