Liverpool's start to the season has been underwhelming at best. The Reds may have lost Luis Suarez to Barcelona in the summer, but very few of Brendan Rodgers' signings have made an impact.
£100m was spent on reinforcements after finishing second last season, but the likes of Dejan Lovren, Lazar Markovic and Mario Balotelli have struggled to hit the ground running.
Already 15 points behind leaders Chelsea, many have ruled the Reds out of the title race at this early stage of the season, but Rodgers still needs to push for a top four finish and Champions League football again.
In order to do so, he must improve the defence. The additions of Lovren, Javi Manquillo and Alberto Moreno have failed to really solidify a defence which was porous last season, and arguably looks even worse this term.
At right back, Manquillo has failed to really make the position his own, whilst Glen Johnson's dire displays have led to his exclusion from the England national team.
Johnson's contract expires in 2015, and it seems virtually assured that Liverpool will part ways with the former Portsmouth defender next summer - and may have already lined up his replacement.
According to reports in England and in Portugal, Liverpool are eyeing up a January move to sign Benfica right back Maxi Pereira.
The 30-year-old is an international team mate of former Reds star Suarez, and whilst the Uruguayan has made over 300 appearances for Benfica, his contract expires next summer, and with talks over a new deal stalling, A Bola suggest that Liverpool could make a move in January.
A tenacious, energetic full back, he'd certainly add some bite to the Liverpool defence, but he would provide only a marginal upgrade on Johnson.
Liverpool need to be adding more quality to their side rather than someone who will turn 31 by the start of next season, and whilst he'd offer strong cover, that would be on the basis that Manquillo progresses to become first choice for the Reds.
