Despite River Plate's efforts to keep him until year-end, the 18-year-old's desire to wear the white jersey is hastening the move.
According to reports from MARCA, River Plate have been working tirelessly to retain Mastantuono until at least December 2025. With the Buenos Aires club competing in the Copa Libertadores, facing Libertad of Paraguay in the round of 16 in August, their plan was to convince the attacking midfielder to stay and see out the year at the Mas Monumental stadium.
"We've done everything possible to keep Franco with us for the Libertadores campaign," a River Plate spokesperson said. "He's a key part of our squad, and we wanted him to finish the season here."
This strategy was discussed extensively with Mastantuono, with the club outlining a clear plan to delay his departure until after the 2025 season, even if a concrete offer arrived from Europe. However, the allure of Real Madrid has proven too strong.
Sources close to the player indicate that Mastantuono is "thrilled" at the prospect of joining the 15-time European champions, and his enthusiasm is pushing the transfer timeline forward.
Real Madrid have already finalised the deal with River Plate, reportedly worth 45 million euros, a figure that reflects Mastantuono's immense potential. "When a club like Real Madrid comes calling, it's hard for any player to resist," said Argentine football analyst Juan Pablo Varsky. "Franco's talent is undeniable, and his move feels like a matter of when, not if."
The player's determination to make the switch as soon as possible has overridden River Plate's hopes, with the transfer now likely to be completed in days or weeks.
River Plate have reluctantly accepted that Mastantuono's will is decisive in this transfer. "The player's desire is paramount in these situations," a club official admitted. "If Franco is set on leaving, we can only wish him well."
The attacking midfielder, known for his vision, flair, and ability to unlock defences, has been a standout in Argentina's Primera División, drawing comparisons to compatriot Angel Di Maria.
As Real Madrid prepare to welcome their latest South American gem, River Plate are left to regroup and focus on their Libertadores campaign without their prized asset. Mastantuono's departure marks the end of an era for the Argentine giants but signals the start of a promising new chapter in Madrid.
