The 2026 World Cup is officially scheduled, prompting national teams like Argentina to prepare accordingly. For Argentina, the primary focus is on the definitive roster that coach Lionel Scaloni needs to present to FIFA prior to their debut in the tournament. This World Cup will take place in the United States, Mexico, and Canada, and it is the first to expand to 48 teams while maintaining the roster limit of 26 players as seen in the previous edition held in Qatar in 2022.

FIFA mandates that the final list of 26 players for the 2026 World Cup is to be submitted about ten days before the tournament kicks off. This deadline is uniform across all participating teams, ensuring consistency in the submission process. Last year, the deadline was also set at ten days prior to the event, reflecting FIFA's commitment to the same regulatory framework for this tournament.

After the roster is submitted, it is considered final, and any changes are strictly limited to serious injuries that must be supported by medical documentation and require explicit approval from FIFA. This structure ensures that teams can adequately prepare while following transparent and fair processes regarding player selection and modifications.
