Real Madrid is preparing to kick off the 2025/26 season with major moves. The arrival of Franco Mastantuono, the young prospect from River Plate, has captured everyone's attention. The 17-year-old Argentine joined the club for a record fee, but he still can't train with the first team.
Mastantuono landed in Spain last August 2. The club gave him a formal welcome through its social media, but the official presentation hasn't taken place yet. Everything indicates that this moment will come very soon.
FIFA restrictions
The reason for this wait is FIFA's regulations. The so-called Rule 19, which protects minors, prevents Mastantuono from officially training with the first team. This regulation aims to prevent child trafficking and the labor exploitation of young footballers.
For now, Mastantuono can't set foot in Real Madrid's facilities, neither Santiago Bernabéu Stadium nor the Valdebebas Sports City. Even so, his development doesn't stop.
According to outlets like Marca, he follows training routines under the supervision of the coaching staff led by Xabi Alonso. He also follows a strict nutrition plan to be ready when the time comes.
Official presentation and jersey number
The wait will end next Thursday, August 14. On that day, Mastantuono will turn 18 and will be able to formally join the team. The club has scheduled his presentation for that same day, and he is expected to start training with his teammates immediately.
It is confirmed that the young forward will wear the number 25 on his jersey, a symbolic choice that generates great anticipation among fans. Although he will need a period of adaptation, he will be available for Xabi Alonso from day one.
Implications for Arda Güler
Mastantuono's arrival puts Arda Güler on alert. The young Turkish talent could see his participation in the starting line-up reduced. According to some outlets, Güler's position on the field is at risk, and he could spend more time on the bench while Mastantuono establishes himself.
This situation reflects the fierce competition that characterizes Real Madrid. Every signing aims to strengthen the team, but it also creates uncertainty for the players who were already on the roster.
Schedule and expectations
Real Madrid will debut in La Liga next Tuesday, August 19, against Osasuna. It will be the first challenge of the season and, most likely, we'll see how the pieces fit together in the attack. Mastantuono's inclusion could change the team's dynamic from the start.
The club is betting on young talent and on keeping its tradition of impactful signings. The season promises intense emotions and strategic decisions that will shape the immediate future of its players.
