Mastantuono is expected to join Real Madrid from River Plate after participating in the Club World Cup. The expert believes that one of the team's current midfielders will be released to make a first-team position available for the young player.
It is mentioned that Brahim Diaz, who has renewed his contract, may not be a part of the team's future plans. Additionally, Rodrygo and Arda Güler are also being considered for release as the team looks to give them new opportunities.
Among the players mentioned, Arda Güler seems to have the most attractive options for other teams. However, Real Madrid is hesitant to let him go as they want to give him a chance to prove himself.
It is worth noting that this decision is part of the team's strategy to develop young players and give them opportunities to shine.
