Kenneth Omeruo scored the winner in Nigeria's 1-0 victory over Guinea in the African Cup of Nations on Wednesday.

The Chelsea defender's 73rd minute header made the Super Eagles the first time to qualify for the last-16 stage.

Omeruo rose like a colossus above the Guinea defence to nod home Moses Simon's corner.

They now have six points from their two games after a 1-0 win over Burundi in their first match on Saturday.
