Nigeria cruised to a 3-1 victory over Sudan in the Africa Cup of Nations, securing a place in the last 16.
The Super Eagles took the lead in the third minute.Nigeria doubled their lead on the stroke of halftime when the ball was deflected in off Taiwo Awoniyi, and Simon added a third straight goal after the restart. Sudan's Walieldin Khedr equalized from the penalty spot after Ola Aina was penalized for a challenge.
Following a video assistant referee review, the Nigeria right-back was adjudged to have fouled Secretary Birds defender Mustafa Karshoum by pulling his shirt as a corner was swung in.
Nigeria had won their Group D opener against Egypt 1-0, and the result against a side ranked 125th in the world was never in doubt after Villarreal forward Chukwueze slotted into the bottom left-hand corner from the centre of the box.
The Nigeria Football Federation's decision to replace long-serving coach Gernot Rohr just four weeks before the tournament looks to have paid off, as interim boss Augustine Eguavoen once again saw his side put in a largely dominant performance in Garoua.
The second was a somewhat freak goal, as a clearing header from Salaheldin Nemer cannoned in off Awoniyi, but the West Africans could have had further first-half goals as William Troost-Ekong had an effort blocked and Joe Aribo hit the post.
The Super Eagles, who are chasing a fourth Nations Cup triumph, know they will face a third-placed side in the last 16 if they can top Group D, and they round off their group campaign against Guinea-Bissau on Wednesday (19:00 GMT).
