A pulsating final match in the Under 17 Championships saw Brazil crowned champions for the fourth straight tournament, as they squeezed past their old rivals Argentina to deny them a shot at title glory.
The Albiceleste went into the game knowing that they had to win by two goals or more to lift the Championship for only the third time in history, but received a hammer blow on the half hour when Lucas Piazon's cross was turned in by Leonardo to give Brazil the lead. Ezequiel Baez headed home a corner to almost immediately level proceedings, but from that moment the Argentine youngsters were always chasing the encounter.
Guilherme hit the third goal with 33 minutes on the clock, crashing home a long-range drive to put Brazil back in the driving seat. Barbosa Teixeira scored the third 13 minutes from time to assure the Canarinha triumph.
River Plate starlet Federico Andrada hit his fourth of the campaign late on for an Argentine consolation, but the Ecuadorian night belonged to Lucas Piazon and his Selecao team-mates as they lifted their 10th U17 title out of 14 available to continue their dominance at this level.
Ecuador 1-1 Uruguay
Uruguay saw a slim chance for a first ever Under 17 triumph slip through their fingers at the weekend, as they could only draw against hosts Ecuador to finish second overall.
The Celestita went into the final match needing a victory to have any chance of toppling Brazil at the top, and also needed Argentina to beat the Canarinha in the final match later on the same evening. They started off bright and in a swashbuckling mood, taking the lead in the first half thanks to a strike from Juan Manuel San Martin to keep the dream alive.
In front of their own fans however the Tricolor refused to buckle, and after withstanding heavy pressure tied the game with an hour gone. Jose Cevallos slotted home a penalty for his third goal of the campaign, and the Uruguayans had to relinquish their hopes of glory.
Colombia 2-1 Paraguay
In the final round's dead rubber match Colombia recorded their first victory of the stage with a win over Paraguay, who finished last with a disappointing one point from five encounters.
Both teams had already given up hope of making the World Cup to be held in Mexico later this year, but all the same fought hard in a match crucial for pride and to avoid occupying the bottom spot of the final stage.
It was the Cafeteros who imposed themselves early on, with a first half double strike from Fabian Cubero Seguro putting the team into a commanding position. The Independiente striker finished joint top scorer in the Colombian side, sharing the honour with Cristian Valencia on four each.
Some consolation came for Paraguay through Alan Benitez, who struck in the first minute of injury time after the two teams squandered chances to get on the scoresheet. After an encouraging preliminary round though, the Albirroja will be disappointed that their campaign petered out when it really mattered.
