Liverpool boss Jurgen Klopp admits a new fullback signing could be on the agenda this summer.
While Neco Williams has emerged from the Academy as a backup option at right-back, Liverpool are short of dedicated senior alternatives on either side of defence.
And Klopp said: "We think constantly about our situation. We know that we need to find solutions for that.
"With Neco Williams we have a real prospect in the team already. It's really nice to have.
"We will have other solutions for those problems, but finding the next Trent (Alexander-Arnold) and next Robbo (Andrew Robertson) is difficult, but may be possible.
"We will work on that 100%."
