Although he was introduced as a first-team player, Real Madrid registered   Mastantuono   as a reserve team player and   wore the number 30 shirt   to clear the way for the possibility of signing new players before the September 1 deadline.

Immediately after the match, Miguel Galán, president of CENAFE (the Spanish National Training Center for Football Coaches), declared that Madrid had been caught using an ineligible player. He wrote on social media:   “In the 67th minute, when Mastantuono entered the field, the violation occurred   . Osasuna has 24 hours to appeal.”

According to Galán, Mastantuono’s signing with Real Madrid’s reserve team was an act of “false goodwill.” In fact, during   the presentation ceremony   , the player was clearly presented as a first-team signing. This method is considered an attempt to circumvent the regulations regarding the number 1 to 25 for first-team players, thus expanding their right to choose their squad.

Article 125 of the Spanish Football Federation (RFEF) statutes stipulates that relations between the first team and the reserve team cannot be used to circumvent the spirit of the regulations. Any agreement that “violates the law” is void. Galán argues that this is a typical case, in which Real Madrid deliberately uses registration to increase the number of first-team players beyond what is established in the regulations.

However, for   Real Madrid   to be sanctioned, Osasuna or the competent authority must prove deliberate fraud in the registration process. That is, in addition to Mastantuono having a valid license, it will be necessary to prove that Real Madrid used the B team’s profile to evade justice.

The trial will focus on the evidence: how Real Madrid communicated with the RFEF, how the club explained the recording, and whether there is any basis to claim the act was fraudulent.
