Photos: Liverpool manager Jurgen Klopp in conversation with returning Jon Flanagan in training

Flanagan has not featured for the Reds since the last day of the 2013/14 season as he has struggled with a knee injury.

The returns from injury seems to be coming thick and fast for Jurgen Klopp, and one of the longest injury lay-offs the Reds have had on their hands may be drawing to a conclusion with the site of Jon Flanagan in training with the Reds.

It certainly hasn't escaped the Liverpool manager's attention as the pair were snapped in conversation at Melwood this week, with the side preparing for their League Cup quarter-final with Southampton at St Mary's on Wednesday night. 

Flanagan has not featured in a competitive game for the Reds since the final day of the 2013/14 season in a 2-1 win over Newcastle United, where has substituted. 

Ever since he has been struggling with a knee problem. He did feature in the pre-season of 2014 before being ruled out until the following March - when he featured in a charity game for both Steven Gerrard and Jamie Carragher - but hasn't kicked a ball in anger ever since as his injury needed further surgery and treatment. 

During his time in the Liverpool side he looked a good prospect and was earning a reputation for being a tough tackling defender. 

It won't be lost on his manager that Flanagan has played in both the right and left full-back role at senior level, and given the seeming reliance on Nathaniel Clyne and Alberto Moreno to play nearly every game at the moment, another fit body in that area of the field will be welcome. 

The 22-year-old does face a bit of a fight to reclaim his place in the side thanks to the form of the aforementioned duo, but Klopp is reportedly willing to give Jose Enrique the opportunity to salvage his Liverpool career having been exiled by Brendan Rodgers, while Connor Randall has been spending a lot of time with the first team, including being handed his senior debut in the League Cup win over Bournemouth in October.
