The brace takes the Selecao skipper up to 42 goals in just 59 appearances for the Brazilian national side, and the Barcelona forward has also netted 10 times in La Liga this term.
Asked if he was in the best run of form in his career, the 22-year-old trickster told Globo: “I think so! It’s another country and another stadium to keep in my heart.
“I didn’t expect this, I couldn’t be happier, but I always want more and I don’t want to remain at this level. Thigs are flowing now.
“We have great players, not only with the Selecao but in Brazil as a whole. Players keep coming in and coming out but we never lose rhythm. We were great out there tonight.”
Chelsea star Willian was also on target to add to a Semih Kaya own goal, and Brazil have now won their last five games without conceding a single goal.
