Enzo Fernández, who was the hero for Argentina in their semifinal victory, became a pivotal figure for the wrong reasons in the 2026 FIFA World Cup final against Spain. His red card in second-half stoppage time significantly hampered Argentina's chances, contributing to their 1-0 loss in extra time.

Argentina struggled to generate offensive opportunities throughout the match, failing to register a shot in regulation against Spain's disciplined defense. As the game neared the end of regulation and headed toward extra time, the team hoped to capitalize on a counterattack opportunity.

However, Fernández lost his composure in the 82nd minute, receiving a yellow card for dissent. This initial booking proved to be a critical misstep. Ten minutes later, in the 90th minute, Fernández committed a reckless challenge on Pau Cubarsí, leading referee Slavko Vincic to issue a second yellow card and, consequently, a red card.

With Argentina down to 10 men and the match heading into a grueling 30 minutes of extra time, the task of securing victory became almost insurmountable. Fernández slowly walked off the field as Spanish fans celebrated and Argentine supporters fell silent, acutely aware of the team's diminished prospects.

Fernández joined an exclusive and infamous list, becoming only the sixth player to be sent off in a FIFA World Cup final. While Argentina was largely outplayed by Spain, Fernández's red card effectively extinguished any remaining hope of overturning the deficit. His crucial mistake will now be a defining moment of his World Cup tournament, overshadowing his earlier semifinal heroics.
