Real Madrid have completed the signing of highly rated Argentine midfielder Franco Mastantuono from River Plate, the Spanish club confirmed on Thursday. The 16-year-old will officially join the squad once he turns 18 in August 2025, as per FIFA regulations, and has agreed to a six-year contract with Los Blancos.
The deal, reportedly worth around €20 million plus add-ons, reflects Real Madrid’s continued focus on scouting and investing in South American talent. Mastantuono has been one of the most talked-about young prospects in Argentina this year, earning first-team minutes at River Plate and attracting attention from top European clubs. Known for his technique, vision, and maturity beyond his age, Mastantuono made his senior debut at just 16 and impressed scouts with his creative ability in midfield.
Real Madrid’s move for Mastantuono follows their successful strategy in signing young stars like Vinícius Júnior, Rodrygo, and Endrick before they turned 18. The club plans to integrate Mastantuono into the squad gradually, with initial development expected under the club’s Castilla setup before promotion to the senior team.
River Plate have wished the teenager well and are understood to have included a sell-on clause in the transfer. The signing adds further promise to Real Madrid’s long-term project, with Mastantuono seen as one of the most exciting prospects to emerge from Argentina in recent years.
