Lionel Scaloni called for greater consistency with the VAR after Argentina were denied a winner against Paraguay.
Nicolas Gonzalez cancelled out Angel Romero's penalty at La Bombonera on Thursday and Argentina thought they had a third straight win to begin World Cup qualifying when Lionel Messi scored in the second half.
However, the goal was ruled out after a VAR check for a foul that started Argentina's passing build-up, and Scaloni's men were held to a 1-1 draw as they moved onto seven points from three World Cup 2022 qualifiers.
