At just 16 years old, Mastantuono is already a regular in River Plate’s first team, according to Marca. Real Madrid is reportedly negotiating with River Plate for Mastantuono and is confident of outbidding other interested clubs for the young talent. Real Madrid’s advantage is strengthened by the involvement of Santiago Solari, a former coach and player of the club who now works with River’s management.

Mastantuono’s contract includes a €45 million release clause, but Real Madrid values him closer to €25 million. Manchester City, led by Pep Guardiola, are also interested, having previously signed Julian Alvarez from River Plate two years ago.
