Marca reports that there is a potential link between Franco Mastantuono and Real Sociedad, and that this is happening while new names are emerging.

According to Team Talk, Real Sociedad is interested in Franco Mastantuono, an 18-year-old Argentine winger from Real Madrid who also holds Italian citizenship. Real Madrid is prepared to allow a temporary departure for the teenager this summer to aid his development and prefers a loan deal with no purchase option. Juventus have made contact, and Sporting CP, Benfica, Villarreal, and Como are also reportedly interested in the player. The four-cap Argentina international joined Real Madrid from River Plate in August 2025 for a fee reported to be €45 million. He has a Transfermarkt market value of €45.00m. During the 2025/2026 LaLiga season, he made 23 appearances and scored one goal.
