Five minutes of magic in the first half was all Nigeria needed as the Eaglets punished the Brazilians with three successive goals.
Victor Oshimen got the curtain raiser as he broke the deadlock in the 29th minute to score his eighth goal of the tournament.
Kinglsey Micheal doubled the advantage for Nigeria moments later with a nice volley while a long shot from range from Udochukwu Anumudu in the 34th minute effectively killed the game.
Brazil came all out with the attempt get back into the game in the second half but the Eaglets held their own to become the first team to make it to the semi final.
The second half had very few clear-cut opportunities, with Funsho Bamgboye and Evander going closest for either side.
With the win, the Eaglets will head to Concepcion for Thursday’s semi-final against the winner of tomorrow’s quarter-final between Ecuador and Mexico.
Nigeria has never lost a semi-final match in the history of the FIFA U17 World Cup.
