Spanish journalist Isaac Foto, who is close to La Liga, the Competitions Committee, and the Spanish Football Federation, confirmed that there is no truth to the media speculation regarding Franco Mastantuno's ineligibility to play with Real Madrid's first team.

Real Madrid had decided to register Mastantuno with Castilla, assigning him the number 30.

Foto clarified that registering players under the reserve team to participate with the first team is a legal and common practice in various Spanish clubs, and does not constitute any violation of regulations.

The source added that even if any club were to file an official complaint, the player's participation with Castilla would completely close the case and provide no legal basis for the complaint to proceed.

Thus, Foto puts an end to the ongoing debate regarding the matter, confirming that the situation is normal and compliant with the regulations of the Spanish Federation.
