For the past five years, the right-hand side of Liverpoolās defence has been completely monopolised by one man: Trent Alexander-Arnold.
Plenty of players have come and gone in the intervening years, but Trent has remained a constant. Liverpool and Jurgen Klopp could rest safe in the knowledge that no matter what improvements needed doing elsewhere, the right-back position was nailed down.
Unfortunately, that feeling has started to weaken somewhat over the course of this season. Now, with Klopp starting to use Alexander-Arnold more centrally, there is an idea that the 24-year-oldās position is potentially up for grabs.
Liverpool have young Conor Bradley and Calvin Ramsay in reserve, but neither looks quite ready for regular first team football. As a result, if Klopp wants a right-back other than Trent next season, heās going to have to look for an external candidate.
With that in mind, here are three right-sided full-backs who the Reds could theoretically target this summer.
Ivan Fresneda
If reports are to believed then Liverpool have actually already been scouting one of Europeās most promising young right-backs. Ivan Fresneda has burst onto the scene at Real Valladolid this season and looks set for a big career.
There was an expectation that the āfantasticā 18-year-old may leave his club in January. But despite plenty of attention from the likes of Arsenal, Fresneda ended up staying put.
However, come the summer time the young Spaniard will surely be on the move. Fresneda may feel like a slightly too-young option to take over from Trent, but heās already making his name as one to watch.
Jeremie Frimpong
Bayer Leverkusenās Jeremie Frimpong has announced himself as a potential superstar this season. With eight goals and six Bundesliga assists for Xabi Alonsoās side, the 22-year-old has shown himself ready for a step up.
According to Fabrizio Romano, three European giants have already spoken to Frimpong about making that step. Romano claims that all of Manchester United, Barcelona and Bayern Munich have approached the Dutchman about a move.
He may not come as cheap as someone like Fresneda, but Frimpong would look like a ready-made option if Liverpool need it.
Benjamin Pavard
The final option is one who may not excite fans as much as the other two on this list. Nevertheless, Benjamin Pavard remains one of Europeās top-level right backs.
Furthermore, Pavard looks ready to move on from Bayern Munich this summer. As per the France international himself via Gazzetta dello Sport, heās looking for a new challenge this summer.
If Liverpool are on the hunt for a new right-back, then that should certainly pique their interest. With one year to run on his deal in Bavaria Pavard shouldnāt be hugely expensive and the Reds have a good recent relationship with Bayern. A deal shouldnāt be all that difficult to get done.
Thereās also the added bonus that the World Cup-winner is adept at centre-back, too. Klopp is reportedly actively looking for another option in the middle of his defence. Pavard could therefore solve two issues for the manager in one go. Something to think about.
Chances are that Klopp is merely tweaking Trentās position with his long-term future still at full-back. But if Liverpool do want to dip their toes into the market this summer, these three would be where weād start.
