Lionel Messi's Instagram message celebrating Argentina's World Cup win has become the most popular post in the social media platform's history, with 56 million likes.

Messi finally won international football's greatest prize after Argentine edged out France 4-2 on penalties after a thrilling 3-3 draw in Sunday's final at Lusail Stadium.

For the seven-time Ballon d'Or winner, it is the final rubber stamp on his status as the greatest footballer of his generation, and arguably the greatest of all time.

Now, Messi has another record to his name, with his post in the wake of Argentina's success surpassing the previous high-water mark held by the World Record Egg, which gained 55.9 million likes.

"Thank you very much to my family, to all who support me and also to all who believed in us," the 35-year-old wrote in his caption.

"We demonstrate once again that Argentines when we fight together and united we are capable of achieving what we set out to do.

"The merit belongs to this group, which is above individuals. It is the strength of all fighting for the same dream that was also the dream of all Argentines... We did it!!!"

Messi, who was named the World Cup Golden Ball recipient for the second time, scored twice in Sunday's final, and netted the first successful penalty of his side's shoot-out.
