Two right-backs who were prominent first team figures last season are both right-backs, now Liverpool are trying to land another one - so what does it mean for the existing players?
Liverpool are interested in taking Atletico Madrid full-back Javier Manquillo on a season-long loan deal with a view to a permanent transfer according to reports in the Spanish press, which is now being reported locally in the Liverpool Echo.
The Reds have been searching for a full-back for much of the summer in order to bolster their defence, and the Echo's report indicates that a deal is some way off.
Manquillo is a right-back, and Liverpool currently have two of them in real contention for a starting place in the form of Glen Johnson and Jon Flanagan, which makes the pursuit of the Spaniard an interesting one - so what will it mean for the right-backs currently at the club?
Johnson is entering the final year of his contract at Liverpool and is playing for his future this season, if he sticks around. Brendan Rodgers sees Johnson as an important part of his side, it seems, despite some poor form last season.
Flanagan played much of last season at left-back for the Reds, but with Jose Enrique returning to full fitness, along with well-documented pursuits of other players who play in that position.
However there have been occasions when 20-year-old Manquillo has filled in on the left side for Atletico Madrid as well, so his versatility would be an attraction for Brendan Rodgers.
But there is nothing to suggest that Liverpool have given up their pursuit of a left-sided full-back to head into the new season with in order to give the team some more balance.
With the terms of the deal suggesting an initial loan move for the young Spaniard, it could be a case of seeing how things go with regards to Johnson.
At the end of the season, Johnson could depart the club on a free transfer, meaning that another full-back may need to come in on permanent basis.
Martin Kelly's career seems to have hit a stumbling block following recovery from a serious knee injury, and is probably seen as a player who could have the talent to perform at right-back but his injury record doesn't fill anybody with confidence for him to be a regular.
If Manquillo comes into the club, and impresses, then there is nothing to suggest he couldn't be a big part of the Liverpool side going forward in the coming years. Though it is likely that he and Jon Flanagan could be in the same team but playing on opposite flanks, or competing for the right-back slot.
Would Manquillo be a good signing for Liverpool?
