Real Madrid have signed 17-year-old Argentine sensation Franco Mastantuono from River Plate for a record-breaking 45 million euros (£38.5m), activating the attacking midfielder’s release clause. The transfer fee marks a new high for the Argentine club, underscoring Mastantuono’s immense potential.
The young star made history last week as Argentina’s youngest-ever debutant in a competitive match, coming off the bench in a 1-0 World Cup qualifying win against Chile.

Mastantuono has been a regular for River Plate’s first team over the past two seasons, earning acclaim for his performances, including becoming the youngest player to score in the iconic River Plate-Boca Juniors derby.
His six-year contract with Real Madrid will commence on August 14, 2025, his 18th birthday, aligning with FIFA regulations.
Mastantuono is Real Madrid’s third signing this summer, following defenders Trent Alexander-Arnold from Liverpool and Dean Huijsen from Bournemouth.
The acquisition signals the club’s continued investment in young talent, with Mastantuono expected to bolster their attacking options.
Fans eagerly await his integration into the squad, as Real Madrid aim to maintain their dominance in La Liga and European competitions.
