Holders, Golden Eaglets, progressed into the last eight of the FIFA U-17 World Cup after whitewashing their Australian counterparts 6-0 early on Thursday morning in Chile.
An hattrick from Victor Osimhen, a spot kick from skipper Kelechi Nwakali and goal a piece by Edidibong Essien and Samuel Chukwueze pitched Nigeria against Brazil in the quarter final stage of the competition.
Earlier in the day, Brazil edged past a brave New Zealand side with a stoppage-time penalty kick to win 1-0.
Osimhen opened scoring in the 22nd minute via a solo effort.
The forward dribbled past two defenders to put Nigeria ahead.
Just after Nigeria grabbed the opener, the Aussies came close to levelling up but Eaglets’ custodian, Akpan Udoh, was well positioned to deny them the equaliser.
Again, the Nigerians were rewarded as Funsho Bamgboye was tripped off the ball in the vital area.
Skipper, Kelechi Nwakali stepped forward and coolly placed the kick in the net at exactly 25th minute to make it two.
Desperate to reduce the tally, the Australian gaffer, Tony Vidmar, introduced Charlie Devereux for Jake Brimmer, but time was too little for the new entrant to make an impression as score line stood at 2-0 at first half.
On resumption for the second half, the Aussies launched several attacking forays into the Nigerians goal area but their efforts were curtailed by John Lazarus, David Enogela, Lukman Zakari and Kingsley Michael in the defence.
Edidiong Essien and Samuel Chukwueze went ahead to compound the woes of their opponents by two more goals towards the closing minute of the tie.
Nigeria will slug it out with Brazil in the quarter final on Sunday.
