The Spaniard can become a mainstay of the Liverpool back-four for the next 10 years if the Anfield side land him this summer.
Liverpool must aggressively pursue Sevilla's Alberto Moreno this summer.
The Reds have been linked with a move for Spanish left-back and are believed to preparing an offer for the €22million-rated defender.
Sevilla president Jose Castro revealed to the club's official TV station that the Anfield side were keen on his player, but stressed that the Europa League winners are under no pressure to sell following their flourishing financial results earned largely from their European success last term.
Castro said: "It's true that there's interest from Liverpool and we're waiting to see if that turns into a reality, which right now it isn't.
"What I'm clear about is that we'll not force anyone to stay at Sevilla. Whoever wants to leave can do so, but we'll be the ones setting the prices.
"This club is experiencing a time of economic stability and we don't need to sell."
However, an aggressive, big-money pursuit for the 21-year-old could finally see a resolution to a position that has plagued the Reds for years.
The likes Fabio Aurelio, Jose Enrique, John Arne Riise and Stephen Warnock have all played the role to various degrees of success without ever making the spot their own over the last decade.
Reds fans still shudder at the likes of Emiliano Insua, Gregory Vignal and most recently Aly Cissokho's displays on the left side of defence, and that's before we even mention Christian Ziege, Paul Konchesky, Andrea Dossena and Djimi Traore.
To put it simply, the Reds have perhaps been attracted to other areas of a more pressing concern over the last 10-15 years, but there is a feeling that the signing of Moreno will solve that problematic left-back position for the next decade.
The 21-year-old narrowly missed out in a place in Spain's World Cup as he was eventually cut from the final 23-man list for the Brazil tournament.
The Spaniard will add pace and power down the left, and will cost at least £10 million less than what Southampton are reportedly asking for Luke Shaw.
Ashley Cole would provide the Reds with a ready-made top-class operator in the left-back role, but at 33, the stop-gap signing would only be prolonging the inevitable need to sign a left-back.
Doubts persist over the fitness and quality of Jose Enrique, while Jon Flanagan was asked to play the unfamiliar role last season, due to Cissokho's inability to adapt to the rigours of Premier League football.
It is about time Liverpool signed a long-term occupant of the left-back role, and Moreno could be the ideal candidate.
