A stirring speech made by Lionel Messi before Argentina's Copa America win against Brazil has been revealed in a new documentary about the tournament.

Messi captained Argentina to the trophy last year -- his first senior honour for his country after a host of near-misses -- with a 1-0 victory against Brazil in the final at the Maracana.

Netflix are set to release a documentary about Argentina's winning campaign called Sean eternos: Campeones de America ("Be eternal: Champions of South America") and a trailer for the series sheds light on how Messi inspired his teammates ahead of the final.

"Forty-five days without seeing our families, boys," Messi said in the dressing room before the game. "We had an objective and we're one small step away from achieving it.

"There's no such thing as coincidence, boys. Do you know what? This trophy was meant to be played in Argentina and God brought it here -- God brought it here so that we could lift it in the Maracana, boys, so that it could be more beautiful for everyone.
