Argentina beat France on penalties in the World Cup final on Sunday, winning 4-2 after Kylian Mbappe's hat-trick ensured the game ended level following extra time.
Gonzalo Montiel scored the deciding penalty to give Argentina their third World Cup and prevent France becoming the first team in 60 years to retain the trophy.
But a truly remarkable game saw Messi scoring twice and Mbappe becoming the first player since England's Geoff Hurst in 1966 to net a World Cup final hat-trick in a game that ended 3-3 after extra time.
Messi had opened the scoring from the penalty spot midway through the first half before Angel Di Maria doubled Argentina's lead in the 36th minute.
But the astonishing Mbappe breathed life into the holders as he pulled one back from the penalty spot with 10 minutes to go before equalising just 60 seconds later to force extra time.
Messi then seemed to have decided the contest in Argentina's favour once and for all when he scored in the 109th minute, only for Mbappe to net from another spot-kick, bringing the game level at 3-3 and forcing a shoot-out.
It is the second time in five World Cups that France have lost the final on penalties after they were beaten by Italy in 2006, and it is Argentina who are champions for the first time since 1986.
