With Jamie Carragher approaching the final years of his career, not to mention the Liverpool defence at times leakier than a colander that has been blown in half, you'd think that any move for Swansea City's Ashley Williams would be a wise one for manager Brendan Rodgers.
However, with Reds revival slowly beginning to pick up momentum, the backline is in fact the least of the problems for the club. While Williams would make a welcome addition, there is no chance he'll force his way past the first-choice defensive pairing of Martin Skrtel and Daniel Agger.
Skrtel may've started two less games than Williams, but has kept one clean sheet more than the Swansea defender. However, with the two conceding the same amount of goals, the latter's goal conceded per game figure is slightly worse than the former.
Skrtels' defensive capabilities have been far superior to the of Williams this season, with the Liverpool centre-back achieving a higher aerial and tackle success percentage.
In terms of passing, the 28-year-old again dominates the statistical comparison, with Skrtel boasting an improved pass completion percentage, albeit having attempted fewer balls to his teammates.
Despite starting one game less than Williams this season, Agger has kept two more clean sheets than the Wales international, while his goals per game conceded figure is significantly lower than the Swansea vice captain.
Defensively, the Dane is the stronger of the duo in the air, winning 60% of his aerial duels compared to Williams' 56%, but Agger's tackle success is just under 15% worse than the 28-year-old. However, the Liverpool centre-back has made fewer defensive errors at just over the midway point of the domestic campaign.
Passing wise, Agger is by far the stronger of the two defensive candidates having attempted more passes than Williams at a higher completion rate.
While Williams would make a decent back-up to Liverpool's defensive duo, the fact of the matter is he would be nothing more than third choice at Anfield. Granted, he worked with Rodgers during their respective time together at Swansea, but with the defender entering the peak years of his career; chances are he would favour first-team football, not playing second fiddle, regardless of the stature of Liverpool.
