Real Madrid has confirmed the signing of Argentinean teenager Franco Mastantuono from River Plate.

The Spanish club has held off stiff competition from other major European clubs to sign the 17-year-old who just recently became the youngest player to ever represent the Argentinean national side.

The attacking midfielder has agreed to a six-year contract and will join Real Madrid in August after playing the Club World Cup with his current club.

"Real Madrid C.F. would like to announce that Franco Mastantuono will join the club for the next six seasons, from 14 August 2025 (when he celebrates his 18th birthday) to 30 June 2031," confirms the club website.

River Plate has published details of the sale on its website, citing the total cost of the player for Real Madrid as 63.2 million euros (72.6 million US dollars).

Mastantuono becomes Real Madrid's third signing of the summer, following the arrivals of Dean Huijsen and Trent Alexander-Arnold, who was presented to the press and supporters on Thursday. His arrival takes the club's total spend for the summer to around 133 million euros.
