Why Fiorentina Beat the Competition
Several clubs across Europe monitored Mastantuono’s situation, including AC Milan, Roma and other sides interested in securing the teenager on loan. However, Fiorentina moved quickest in negotiations and ultimately reached an agreement with Real Madrid. The Italian club’s project, which offers the promise of regular Serie A football, proved decisive in persuading both the player and Madrid that the move would benefit everyone involved.
There were other clubs interested in this loan deal, like Roma and Valencia, but Fiorentina ultimately prevailed. River Plate were also interested in bringing their academy graduate back to Argentina, while Madrid reportedly rejected an approach from a Saudi Arabian club. The Spanish side preferred Mastantuono to remain in Europe, where he can continue adapting to the demands of the continent’s leading leagues.
The Viola had been monitoring Mastantuono for several weeks, with sporting director Fabio Paratici leading negotiations. Talks intensified during Real Madrid’s pre-season friendly against Fiorentina in Austria, where executives from both clubs held discussions regarding a possible loan agreement.
A Challenging First Season at Real Madrid
Mastantuono joined Madrid from River Plate last summer as one of the most highly-rated teenagers in South American football for a €45 million fee. However, he struggled to make an impact at the Bernabéu in 2025-26, and Madrid have now decided that a loan in Serie A represents the best option at this stage of his development. Mastantuono made 23 appearances in LaLiga last season, scoring one goal.
There’s no denying that his first season as a madridista was a disappointing one, as he failed to adapt to the pace of European football, so an entire season with consistent playing time and a quality role would be ideal for his progress.
Madrid will continue to pay a proportion of the player’s wages during the loan period, with the deal also including a shared salary arrangement between both clubs.

Real Madrid’s Long-Term Commitment
One of the key aspects of the agreement is that Fiorentina will not have the option to sign Mastantuono permanently. Real Madrid have made it clear that the Argentine remains a central part of the club’s long-term plans and will return to Spain at the conclusion of the 2026-27 season.
Madrid have maintained confidence in his long-term potential and are not considering a permanent departure. Real Madrid will surely monitor his development throughout the 2026-2027 season as Mastantuono tries to earn a spot in next year’s rotation.
