Paul Pogba and Kylian Mbappe both scored in the second half to put France out of sight, and they could even afford to see Mandzukic pull a second goal back for Croatia after an very bad Hugo Lloris mistake.
France defeated Croatia by 4-2 on Sunday afternoon but L'Equipe felt that many of their players did not perform well in the victory.
Those of us in Croatia, however, have every reason to be proud of their unbelievable team this tournament, who marched to the top with determination, heart, and their incredible ability to come together as one.
"I do not know where I am", the stunned 27-year-old said while organisers hurried to set up the presentation stage on the pitch.
Zlatko Dalic's side were the better team for the first hour despite trailing, and were pushing France back when they were hit by those two swift hammer blows from Pogba and Mbappe.
Pogba's 59 minute strike saw him become the first United player to score in a World Cup final, capping a superb campaign in Russian Federation following a somewhat hard 2017-18 season with his club back in Manchester.
When he finally emerged from his on-pitch celebrations, the tears had been replaced by a wide smile.
"I thought about taking a Panenka penalty, like Zidane", Griezmann stated post-match, having opted to roll home his spot-kick.
"It was so painful at the Euro, but maybe if we had won it we would not have won the World Cup".
"The group worked so hard and we had some tough moments along the way".
Yet they showed no signs of tiredness as they tore into France from the first whistle, and even when the game looked out of reach they never once let their heads drop, threatening an unlikely comeback when Mandzukic cashed in on Lloris' error.
He had stayed calm under pressure, unlocked the Croatian defense, and been key to victory.
"Now we will party and tomorrow we will party with France and with all the French people", he said, again breaking into an enormous grin.
