Nigeria and Angola made strong starts to the 2019 FIFA Under-17 World Cup after recording victories in their opening pool games in Brazil.
Nigeria thumped Hungary 4-2, though they left it late with three goals in the final 11 minutes to come from behind to record their success.
Midfielder Samson Tijani grabbed a brace, one a first half penalty, while there were further strikes from Usman Ibrahim and striker Oluwatimilehin Adeniyi.
Nigeria will next be in action on Tuesday against Ecuador, who beat Australia 2-1 in their opener.
Angola also claimed a win on their debut in the tournament with a 2-1 success over New Zealand, goals from midfielder Zini and Harry Bark, who put the ball into his own net, spurred them to victory.
They are also back in action on Tuesday and will hope to take a giant step towards qualification for the second stage when they play Canada. Hosts Brazil are the other team in the pool.
Senegal will start their Under-17 World Cup campaign on Sunday when they play United States, while Cameroon are in action against Tajikistan on Monday.
