The South Americans have progressed to the knockout phase after winning all three group games, scoring three goals in each fo their first-round matches.
"It's important for me, this Olympic Games," the Tottenham midfielder told reporters after Wednesday's 3-0 victory over New Zealand.
"Brazil never win this competition. If Brazil win this competition it will be good for the World Cup. For me, I try so hard to stay in the national team.
"Everyone has talked about it. If we win this competition, have possibility for two years in Brazil with the same team. It’s going to be good."
The Spurs man confessed that Brazil were under pressure to play attractive football at the Games but is happy with the standard shown by the Selecao thus far in the tournament.
He explained: "When you wear the Brazil shirt [there is] always pressure. [The Brazilian public] always want to see good football and for us to win the game, win the competition.
"Everyone is playing very good football, not just Neymar, but Pato, Romelu, Marcelo, Thiago [Silva], everyone.
"I think it's good for us because it’s not just one player. The group is strong."
