Sudan vs Nigeria: Eagles dispatch Falcons to reach the round of 16
The Super Eagles made it back-to-back wins in the AFCON for the second consecutive time following a comfortable 3-1 victory over Sudan on Saturday.
Nigeria made their intentions known as early as possible when Samuel Chukwueze opened the scoring in the third minute with a calm finish from close range.
The Eagles created several chances but failed to take any of them with William Troost-Ekong and Joe Aribo all coming close.
Bundesliga-based Taiwo Awoniyi, however, doubled the advantage just before the break, it was his first international goal for Nigeria and what a time to get it.
It was the first time since 1992 that Nigeria's Super Eagles had scored two goals in the first half in the Africa Cup of Nations.
The second half saw Nigeria extend the lead to three goals when the man of the match, Moses Simon combined with Kelechi Iheanacho before calmly putting the ball past Ali Aboeshren to give Nigeria a commanding lead.
Sudan's Jediane Falcons did pull one back from a late penalty but it was nothing but a consolation goal.
