The FIFA U‑20 World Cup groups 24 national teams into six groups of four, with each side playing three round‑robin matches. The top two teams per group and the four best third‑placed squads advance to a single‑elimination knockout stage. Mexico, as a regular participant, must navigate this format while contending with age‑group eligibility rules that restrict player selection to those born on or after a specific cutoff date.
Match scheduling follows a predetermined calendar: group matches occur over ten days, followed by a rest day before the round of 16. Knockout games incorporate extra time and penalty shoot‑outs if necessary. These timing constraints influence squad rotation, tactical preparation, and statistical comparability across rounds.
