#3 Junior Firpo
Junior Firpo has been strongly linked with a move away from Real Betis since the winter transfer window and he would be a great signing for the Reds as a cover for Andy Robertson who had a tireless season with very less rest.
Although he played as a wing-back for Quique Setien's side, he is very good defensively and attacking wise very adept. He was involved in 7 goals in the league last season, scoring 3 and assisting 4 goals in the process although he only started 22 games.
With reported interest from Barcelona as well, it would be interesting to see who he plays for in the upcoming season. But even if he does join Liverpool, it is safe to say he is going to be an understudy to Andy Robertson.
In the current market, he may cost a maximum of £30 million and it would be a good investment for Liverpool.
