Having previously hoped to keep the left-back on a new contract, the Spanish club now looks to be actively working toward a sale — a change in approach that hands Nottingham Forest, and the other suitors chasing the 23-year-old, a genuine opening.
Oso's breakout season has made him one of the more coveted full-backs on the continent, with Tottenham, Newcastle United and Fiorentina joining Forest among the clubs already making contact. The numbers around a deal have shifted too: last week's reporting out of Spain put his price at roughly €10m, well below the €20m release clause once attached to his contract, with Vamos Mi Sevilla suggesting the club had essentially given him an ultimatum — sign an extension or be sold.
What's changed since, according to Diario de Sevilla, is the calculation behind that ultimatum. Oso has only a year left on his deal, meaning this window is genuinely Sevilla's last realistic chance to extract fair value rather than risk losing him for nothing next summer.
That urgency has apparently translated into movement: three or four offers are said to be under consideration, including one from an as-yet-unnamed Premier League club and another from Fiorentina, who TuttoMercatoWeb report have gone in around €12m plus a sell-on clause in an attempt to jump the queue ahead of Forest.
Forest's own left-back options give them reason to push. Luca Netz has featured just seven times since arriving from Borussia Monchengladbach, while Neco Williams — the more established of the pair — is drawing significant interest of his own from Manchester United and Newcastle. Neither represents the settled, long-term solution Oliver Glasner would ideally want in that position, which only sharpens Forest's motivation to get a deal for Oso over the line while Sevilla's door remains open.
Oso's rise has been rapid, forcing his way into Sevilla's first-team picture only over the past year on the back of pace and end product down the left that made him stand out in a side that struggled for much of last season.
That profile is precisely what has drawn interest from clubs across three different leagues, and with the asking price now within reach of several suitors, the coming days could prove decisive in determining where he ends up.
