Melbourne: Gabriel Mercado netted the winner as Argentina pipped Brazil 1-0 in an international friendly at the Melbourne Cricket Ground on Friday.
Mercado scored the lone goal of the match in the first half as Jorge Sampaoli marked his debut as Argentina coach with a win.
The ex-Chile and Sevilla boss made numerous changes after taking over from Edgardo Bauza, who was sacked after a 2-0 defeat in Bolivia in a World Cup qualifier.
