Nigeria wrapped up their Group D campaign at the Africa Cup of Nations with a 2-0 win over Guinea-Bissau at the Roumde Adjia Stadium in Garoua on Wednesday night.
After making eight changes to the side that beat Sudan to seal their last-16 place, Nigeria took time to warm up.
Umar Sadiq opened the scoring shortly after the break following a cross from striker partner Kelechi Iheanacho.
Captain William Troost-Ekong sealed the win after tapping into an empty net after fine work by Moses Simon.
The result sees the Super Eagles top the group with a full haul of three wins (the only team in the competition to do so) and underline their status as one of the outright favourites for the title.
They will have to wait until Thursday night to find out which of the best third-placed sides they face from either Group B, E or F.
Guinea-Bissau, meanwhile, have now gone over seven Nations Cup games without a goal, last scoring in their second match of the 2017 finals when they made their tournament bow.
