Brazil emerged victorious over Tunisia despite going down to ten men just before halftime to secure a 3-1 victory securing their spot in the quarterfinals of the tournament.
Brazil's star forward, Marcos Leonardo, continued his impressive form, opening the scoring with an early penalty kick.
Electing to shoot down the middle, Leonardo sent Tunisian goalkeeper Dries Araoui diving in the wrong direction.
The Brazilian talisman then turned provider, delivering a perfectly weighted pass to captain Andrey Santos, who doubled their lead.
However, the match took a dramatic turn when Brazil's defender Robert Renan was shown a red card for a foul on Tunisian striker Mohamed Dhaoui.
Referee Halil Umut Meler deemed the challenge a clear denial of a goalscoring opportunity, reducing Brazil to ten men.
Buoyed by the support of the home crowd in La Plata, Tunisia dominated possession in the second half and applied relentless attacking pressure.
They thought they had found a lifeline when substitute Raki Aouani displayed exquisite control and finished to score, but the goal was ultimately disallowed after a VAR review revealed that Aouani had handled the ball in the process.
Brazil's coach Ramon organized his team to withstand Tunisia's relentless onslaught.
As the North African team committed numbers forward in search of a comeback, Brazil exploited the space on the counter-attack.
Substitute Matheus Martins and Santos both found the back of the net in stoppage time, sealing a comprehensive victory for the Brazilians.
Although Tunisia managed to salvage a consolation goal through defender Mahmoud Ghorbel's scrappy finish late in the game, it was not enough to alter the outcome.
Brazil aims to lift the FIFA U-20 World Cup trophy for the first time since 2011 and add another accolade to its illustrious footballing history.
