The 2026 World Cup final may have featured a hard-fought victory for Spain, but for many, the tournament's breakout star was not an athlete, but the three-year-old half-brother of Spanish forward Lamine Yamal, Keyne.
Keyne, dressed in a replica Spain jersey, became a focal point of post-game celebrations at MetLife Stadium, darting onto the pitch to embrace his older brother. Yamal, after lifting Keyne in the air, placed a red baseball hat on the toddler's head. The young fan also had a memorable interaction with a New Jersey State Trooper, trying on the officer's cap.
Keyne's presence throughout the World Cup has been a consistent source of viral moments. Spanish media outlets have dubbed him 'the star of the 2026 World Cup' and 'Spain's superstar in the stands.' His popularity surged after Spain's quarter-final win, when cameras showed him waving from the stands. Yamal himself has expressed deep affection for his younger brother, stating, 'My little brother means everything to me. I am in love with him; it feels like he is my son.'
Yamal shared that Keyne had even predicted his own antics, telling him the day before the final that he would stick his tongue out. The younger brother's gestures were visible on the stadium's giant screens, much to Yamal's amusement.
Keyne's bond with his older brother extends beyond the World Cup. He has frequently appeared in Yamal's social media content, including TikTok dances and playful moments during team celebrations. Footage exists of Keyne singing the Barcelona anthem and interacting with the team mascot. Yamal, who brought Keyne to the Ballon d'Or ceremony, has spoken about his desire to provide his younger brother with the childhood he did not have, referencing his upbringing in a deprived neighborhood.
Keyne is the son of Yamal's mother, Sheila Ebana. Yamal's own childhood included a notable moment captured in a 2007 photograph where a young Lionel Messi bathed him. Yamal's family hopes that Keyne might one day have a similar encounter with Messi, should the veteran player continue his career.
