The teams are competing for this trophy
Nigeria are out of the Under-20 Women's World Championship in Russia after a 2-1 defeat to Brazil in the quarter-finals on Saturday.
The South Americans needed a stoppage time strike by Adriane to settle the thrilling encounter at Moscow's Torpedo Stadium.
The Nigerians, cheered on by a noisy and colourful contingent, dominated the early exchanges but failed to convert their chances.
The Falconets paid for their profligacy seconds before the break, with Fabiana
losing her marker after a corner kick, to head the opener past Tochukwu Oluehi.
The West Africans came back from the break and dominated possession with playmaker Cynthia Uwak tormenting the Brazilian defence.
Uwak was on hand to draw the Falconets level in the 80th minute after angling a low side-footed shot into the far corner.
The South Americans rallied and gained their composure in extra-time, with Oluehi receiving a red-card after fouling the advancing Fabiana.
Adriane converted the resulting free-kick after it came off the crossbar to secure a semi-final spot for Brazil.
