Di Maria started for just the second time in the Copa and he justified his selection by scoring the opener midway through the first half. Renan Lodi failed to cut out a long ball forward from Rodrigo De Paul and Di Maria lobbed the stranded Ederson with aplomb.
Argentina’s win was a particular triumph for Barcelona striker Lionel Messi, who picked up his first ever title in a blue and white shirt after more than a decade of club and individual honours.
Messi finished the tournament’s joint top goalscorer with four goals and was elected joint best player along with Neymar. But he was quiet throughout and uncharacteristically missed a golden opportunity to wrap the game up with two minutes remaining.
When the final whistle went, Argentina TV declared “Argentina Champions, Lionel Messi Champion!”
The victory was Argentina’s 15th Copa America triumph and means it now draws level with Uruguay as the all-time leading winners.
Argentina’s win extended its unbeaten streak to 20 matches under Lionel Scaloni and handed Brazil its first competitive defeat since it lost to Belgium in the quarterfinal of the 2018 World Cup.
