Real Madrid says it has struck a deal to sign River Plate midfielder Franco Mastantuono for the next six seasons. It will be a record transfer for Argentine soccer.

Real Madrid have signed River Plate star Franco Mastantuono, the LaLiga club has announced. Mastantuono, 17, is with River in the United States for the Club World Cup, and will join Madrid in August.

Mastantuono agreed to a six-year deal at the Bernabeu, with Madrid staving off interest from Paris Saint-Germain, Manchester United and Chelsea to win the youngster’s signature. River had aimed to keep him at the club until the end of 2025 – after the end of their domestic season – but have now reached an agreement with the European giants.
