Spain are 2026 FIFA World Cup champions, dethroning Argentina, 1-0, in extra time in Sunday's final at New York/New Jersey Stadium.
Lionel Messi and Argentina were vying to become just the third nation to win back-to-back World Cup titles, but instead it was Spain lifting their second overall trophy and first since 2010.
Ferran Torres scored the decisive goal in the 106th minute, taking a headed layoff from Nico Williams and blasting it past Argentina goalkeeper Emiliano Martinéz from just outside the six-yard box.
It was Spain's 20th shot, to Argentina's zero at that point.
Martinéz was a brick wall for Argentina, diving to his left to parry away a Lamine Yamal free kick in the final seconds of second-half stoppage time for one of his 11 saves in the game.
Five minutes earlier, Argentina were reduced to 10 men when Enzo Fernández was sent off for a second bookable offense.
Still, Argentina nearly leveled late in extra time, but couldn't capitalize on a pair of corner kicks, with Giuliano Simeone firing over the crossbar in stoppage time.
