Nigeria topped their group in the African Cup of Nations after a comfortable win against Guinea-Bissau.

Sadiq Umar and William Troost Ekong scored the goals that ensured Nigeria comfortably sailed into the knockout stages of the competition.

Umar had not been in the best form going into the game, but showed his quality when it mattered.

He netted through a great pass from Kelechi Iheanacho, and Moses Simon later set up Ekong to seal the three points.

Nigeria are the only team that are going into the knockout stages with three wins from their three group games.
