Is Lamine Yamal’s Brother Supporting Argentina over Spain in World Cup Final?

A viral social media video featuring Spain star Lamine Yamal’s younger brother Keyne has sparked widespread fan speculation ahead of Sunday’s highly anticipated 2026 World Cup final between Spain and Argentina.

Internet users quickly questioned if the young boy was supporting Lionel Messi’s squad after a video surfaced showing him with bright blue-dyed hair and a matching sports outfit colors closely resembling Argentina’s iconic kit.

However an editorial review confirms the speculation is entirely baseless. The footage is not recent; it was originally posted in May 2026 by the Yamal family’s barber well before the tournament reached its climax. There is absolutely no evidence suggesting Keyne’s style was intended as an endorsement of Argentina. Throughout the tournament little Keyne has been a prominent fixture in the stadium stands with actively cheering on his elder brother Lamine and the Spanish national team.

The final marks the conclusion of a historic World Cup jointly hosted across the United States, Mexico and Canada.

Beyond the pitch the grand finale at the New York New Jersey Stadium will feature a star-studded halftime show with global icons including Shakira, Justin Bieber, Madonna and BTS.
