The No. 10 jersey carries immense historical significance in football, famously worn by legends like Lionel Messi. For Spain, however, Lamine Yamal, who successfully wears No. 10 for Barcelona, will sport No. 19 at the upcoming World Cup. Dani Olmo, with significantly more national team caps, receives the coveted No. 10 due to Spain's strict seniority-based numbering system.

This policy, championed by coach Luis de la Fuente, prioritizes team spirit and respect for veteran players over individual commercial appeal or star power, even for a player as crucial as Yamal. Yamal has thrived with Barcelona's No. 10, succeeding where Ansu Fati struggled, demonstrating his ability to handle the pressure. The article also highlights Gavi wearing No. 9, a number typically for strikers, due to its availability during his debut, further illustrating the team's unique numbering approach.
