The 20-year-old, who has scored three goals this summer, also claimed that the experience in the squad will aid their push against Mexico on Saturday.
"We are experienced. Despite the young age of some of our players, we have been playing football for a long time," he told TV Record.
"We are prepared. After the victory against South Korea, we must rest so that the team is ready ahead of the next game. God willing, we will win the gold medal that all of Brazil wants."
