The left-footed winger spent the season on loan at Getafe, who held an option to sign 50% of his rights for €3m. According to reports, Getafe will not be exercising that option, opening the door for Liso's parent club to consider offers elsewhere.
Sevilla have been credited with interest in the 22-year-old, alongside Levante and Rayo Vallecano, who are also said to be tracking the situation. Interest extends beyond Spain too, with Italian clubs Parma and Venezia both linked.
Despite the overseas attention, journalist Matteo Moretto has reported that Liso's priority for now remains staying in Spanish football, a stance that could work in favour of any of the three LaLiga clubs circling the player.
For Sevilla, the potential move would fit a pattern already established this summer. The club have brought in Jon Guridi and Juan Iglesias as their first additions of the window, both arriving on free transfers or loan deals rather than for significant fees.
Sevilla's approach reflects their financial position heading into the new season. Should the club wish to spend on any incoming transfer, sporting director Jose Ignacio Navarro and head coach Luis Garcia Plaza face an obligation to generate funds through sales first.
Every department of the squad is expected to see changes as Navarro and Garcia Plaza work through their planning for the campaign ahead. Players are due to report on July 3rd for medical examinations over the following weekend, before the first training session of pre-season takes place on July 6th.
The squad has already undergone significant turnover. Cesar Azpilicueta retired at the end of his single season with the club, while Ørjan Nyland and Nemanja Gudelj will also depart once their contracts expire on June 30th.
Loan spells have also concluded for Odysseas Vlachodimos, Neal Maupay and Nemanja Mendy, all of whom return to their parent clubs. Coming back into the fold at Sevilla are Alfon Gonzalez, Marcao Pedrosa and Rafa Mir, each of whom spent time away from the club last season.
With renovations pending for several squad members, players deemed surplus to requirements still on the books, and a market that Sevilla's hierarchy continue to monitor closely, the situation around Liso represents just one of many threads the club's sporting department will need to resolve before the new campaign gets under way. For a player with options across two countries, the next few weeks promise to be decisive.
