France won the World Cup for the second time after beating Croatia 4-2 in a pulsating final in Moscow that included a controversial use of VAR.
A Mario Mandzukic own goal (18) set France on their way in Sunday’s incident-packed showdown, only for Ivan Perisic to fire home an equaliser 10 minutes later.
But seven minutes before half-time, referee Nestor Pitana contentiously awarded a spot-kick for a handball by Perisic after consulting pitch-side replays, which Griezmann converted.
Second-half goals from Paul Pogba (59) and Kylian Mbappé (65) took the game away from Croatia, who did score a comical consolation through Mandzukic after a Hugo Lloris error.
The victory means France boss Didier Deschamps becomes only the third person to lift the trophy as a player and manager, following Mario Zagallo and Franz Beckenbauer.
Deschamps’ risk-averse tactics allowed Croatia to boss the opening stages in terms of possession but it was France that struck first, with their first meaningful attack.
Griezmann whipped in a free-kick with his left-foot and, in a desperate attempt to clear, Mandzukic flicked the ball past his own goalkeeper and became the first player to score an own goal in a World Cup final.
Croatia were not to be deterred by falling behind for the third time in the knockout stages and Perisic drew them deservedly level.
The Inter Milan forward seized the ball on the edge of the box and took a touch with his right foot to take him past N’Golo Kante before rifling a left-footed shot past Lloris, via a minor deflection off Raphael Varane.
