Injuries are currently a big problem for Liverpool - and no more so than at left back.
With Jose Enrique ruled out for 10 weeks after undergoing knee surgery, Aly Cissokho and Jon Flanagan have struggled to make a definitive impact in his place.
Why, then, can Liverpool not swoop in and give the Portugal defender the first-team football he needs ahead of the World Cup in Brazil?
The 25-year-old has enough experience at the top level to really benefit the Reds' back line, with his defensive abilities only surpassed by his speed and urgency going forward.
With Marcelo preferred at left-back by Real Madrid, a loan move could be a very real possibility. The only obstacles appear to be interest from other clubs, with United having almost landed Coentrao in January.
Perhaps the most realistic transfer target for Rodgers' side is one closer to home, with Chelsea's Ryan Bertrand possessing both the quality and motivation to succeed at Anfield.
The Blues, of course, have already offloaded Daniel Sturridge and loaned Victor Moses to the Reds and they would benefit from Bertrand receiving first-team football elsewhere, too.
At 24, the Chelsea full-back still has his best years ahead of him - but there are no signs of him leapfrogging Ashley Cole or Cesar Azpilicueta in Jose Mourinho's starting XI.
Liverpool could well succeed in bringing Bertrand to Anfield as cover until the end of the season and his trophy-winning experience at Stamford Bridge could be of huge use to Rodgers' defence.
There are not many full-backs who can boast an education at Barcelona on their CV. In Martin Montoya, however, Liverpool may have found a potential recruit with the best training in the business - and who could be landed at a bargain price.
Why? The 22-year-old is out of contract with Barca at the end of the season. And with Rodgers already showing an interest in the Spaniard, according to some reports, who better to fill Liverpool's defensive void?
Montoya primarily plays as a right-back but can also deputise on the left, while his relative youth means he can offer the Reds plenty more than one season's worth of cover.
