Sadiq Umar and William Troost-Ekong grabbed the goals as the Super Eagles of Nigeria beat Guinea Bissau 2-0 to maintain their perfect record in the ongoing African Cup of Nations in Cameroon.
The already qualified Eagles looked too strong for the Djurtus of Guinea-Bissau, and made their dominance count with two clinical second-half strikes to claim all three points.
Umar, guilty of missing a number of chances, finally converted after being picked out by strike partner Kelechi Iheanacho, before Ekong made sure of the win with a close range finish following good work from substitute Moses Simon.
Elsewhere in the group, seven-time champions Egypt made it through to the knockout rounds courtesy of a 1-0 win over Sudan in Yaounde.
Sudan and Guinea-Bissau exit the competition with just a point each after three games.
