Casemiro came close with a 25-meter free kick manufactured by Neymar that flew past Romero's left post. Then Nicolás Otamendi stuck out a boot to deflect a diverted shot from Richarlison in the last minute.
The Albiceleste's best chance came during a period of pressure around the hour mark, when Paredes hit a swerving, dipping drive that had Brazil keeper Alisson beaten.
Missing from Argentina's line-up were Manchester City's in-form forward Sergio Agüero, Paris Saint-Germain winger Ángel Di María and Lionel Messi. The captain has sat out Argentina's last three matches, all friendlies, since the country's disappointing last 16 elimination from the World Cup in Russia. He is believed to have asked for some time off from international duty ahead of next year's Copa América in Brazil.
