"I just have to play, help my teammates, help my team".
The world's most expensive player has 11 goals and nine assists in his last 19 games for Brazil.
Pre-tournament favourites Brazil were held by Switzerland and struggled to overcome Costa Rica in the group stage, but impressed in the second half of their last-16 win against Mexico.
Neymar, who only returned from a fractured metatarsal last month, looked close to his best on Monday when Brazil beat Mexico 2-0 to reach the quarter-finals in Russian Federation.
In the first match of the day, Brazil shut out Mexico 2-0 in Samara.
Neymar has had an unspectacular World Cup so far, although by no means unproductive.

Neymar was being defended by many in Brazil, especially because he has been playing well and is helping the team succeed at the World Cup, but he continued to be loudly criticized internationally for his antics. But at ESPN, Tim Vickery argues that Neymar is the result of too many Brazilian referees deeming any physical contact to be a foul, though it does seem like the player has "an exceptionally low pain threshold". It was clear that Belgium were the more exhausted team after 90 minutes of high pressing, so Chadli's goal was key as going into extra-time may have been more favourable for Japan.
"I am confident, Neymar will big time among goals in the matches to come", said Silva.
When Mexico exhausted Brazil created enough chances to have won by more than 2-0.
The victor of the tie will face either France or Uruguay in St Petersburg on July 10.
Martinez certainly had the last laugh, as his decision to bring on Chadli and Fellaini when chasing two (or three) goals was widely mocked on Twitter.
Neymar went on a counter-attack that drew Ochoa from his goal before finding Roberto Firmino with the finest of touches from the outside of his right boot.
