He has now taken to his Instagram page, to clear up speculations.
Had the match ended in a stalemate, Brazil would have only had two points and may have needed to win their final game in order to advance.
"It's not normal to cry in the second game of a World Cup", Brazil's biggest newspaper, O Globo, said.
Costa Rica - rightly anticipating that Brazil would enjoy the lion's share of possession - sat deep but looked risky when they were given the rare opportunity to counter.
Brazil forward Neymar broke down and wept uncontrollably on the pitch at the end of his team's hard-fought 2-0 win over Costa Rica on Friday, it was hard not to be moved by his reaction.
Dramatic late strikes by Philippe Coutinho and Neymar gave Brazil their first win of the World Cup against Costa Rica and broke Central American hearts by sending them out of the tournament.
Ex-Barcelona star Neymar then doubled Brazil's lead in the 97th minute, after an excellent midfield display from the former Spurs star helped Brazil earn all three points.
After the referee stopped play to attend to a Costa Rica player, Thiago Silva sportingly kicked the ball back to Brazil'a opponents.

The 26-year-old had limped out of training earlier in the week with an ankle injury, having received some rough treatment during Brazil's 1-1 draw with Switzerland.
Neymar faced the most devoted of markers in Costa Rica's Cristian Gamboa, the Brazilian spending most of the half hopping over scything tackles or dodging past a barging shoulder.
Neymar's obsession with social media has undoubtedly opened him up to more criticism - and pressure - than ever but former players acknowledged even the most balanced individual is under massive stress in Russian Federation.
Brimming with confidence and oozing with composure, Coutinho's finish in the 91st minute of the game only shows how he performs well under pressure as he simply knew where to be to clean up the possession and result in a goal.
In the next match against Costa Rica, he complained to the referee frequently about not getting calls in his favour. Up next will be Serbia on Wednesday.
Serbia play the Swiss later on Friday, while Costa Rica are out of the tournament with defeats in both games so far.
