This season, Liverpool have used three different players at left-back, be it as a wing-back or part of a four-man defence, but none of Jose Enrique, Javi Moreno or Glen Johnson have looked like the long-term option Brendan Rodgers is looking for.
In the summer, Liverpool will have the opportunity to pursue one of Paris Saint-Germain's best young defenders, and they can't afford to let the chance go to waste.
Today, in Le Parisien, super-agent Mino Raiola confirmed that Brazilian left-back Maxwell will sign another year extension for PSG, taking his contract to the end of the 2016 season.
On its own the deal is a good for the player and club, the 33-year-old has been excellent again this season, but it does cast a huge shadow over the future of France international Lucas Digne.
When the 21-year-old joined from Lille in the summer of 2014, it was expected that after taking one season to settle to life in the capital, the kid from the Parisian suburbs would take over as PSG's starting left-back.
He made 15 starts last season, never once coming off the bench, not a bad return in his first season. This season, so far he has only made 10 starts, and hasn't been given the chance to progress as he would have hoped and expected.
There is a chance now that the former U-20 World Champions will lose his place in the France national team and it won't be long until his patience wears thin.
If Liverpool are in the market for a new left-back, Digne would be the perfect signing. He can play in a back four and as a wing-back, loves to attack, but has the engine and stamina to get back and defend when needed. He is also stronger than he looks and is underrated in the air.
When he breaks forward he is blessed with a wonderful left-foot and likes to deliver early, dangerous ball into the box. He is the archetypical modern full-back and it this stage of his career that he needs to be playing regular football. Sitting on the bench is disrupting his development.
Liverpool would be the perfect next step for Digne if he wants to jump from out of Maxwell's shadow. He already has Champions League experience for two different clubs and was part of France's squad at the Brazil World Cup.
Brendan Rodgers could do a lot worse than pursue a move for Digne this summer.
