Nigeria maintained its perfect record at the Under-20 World Cup in Colombia with a 2-0 win over Saudi Arabia.
Ahmed Musa and Olarenwaju Kayode scored a goal in each half to ensure the Flying Eagles finished top of Group D.
The Flying Eagles had already qualified for the last 16 but the win means they will play England in the last 16 on Wednesday.
England reached the second round with three goalless draws.
Saudi Arabia finished second in the group and will now play Brazil in the second round.
Spain and Colombia are the only other teams to have won all its group matches.
Musa gave Nigeria the lead with a powerful right-footed shot from the top of the area after a perfect pass by Omoh Ojabu two minutes into first-half stoppage time.
Kayode sealed the victory with a goal from inside the area in the 85th, controlling the ball before sending it past Saudi Arabia goalkeeper Abdullah Alsdairy.
Saudi Arabia threatened early and had two great chances from striker Yahya Dagriri.
He fired a long-range shot that forced Nigeria keeper Dami Paul to make a difficult diving save to tip the ball wide in the 37th minute, then missed from near the penalty spot when he had only the goalkeeper to beat a minute into first-half injury time.
