Real Madrid prepares to receive Argentine midfielder Franco Mastantuno following his transfer from River Plate. The seventeen-year-old footballer will begin individual training sessions on Monday, August 4, as regulations prevent minors from practicing with senior squads. Radio COPE confirms that Mastantuno must wait until his eighteenth birthday on August 14 before joining first-team activities and receiving his jersey number. The Spanish giants secured the young talent through a six-year agreement spanning from 2025 through June 2031. Mastantuno becomes the fourteenth River Plate graduate to join the Madrid club, following legends like Di Stefano, Saviola, and Higuain, who made similar transitions from Argentina to Spain.
