Nigeria became the first team to qualify for the last 16 of the Africa Cup of Nations as they beat Guinea 1-0.
Three-time winners Nigeria scored the only goal in the 73rd minute when Moses Simon’s right-wing corner was headed in at the near post by Kenneth Omeruo.
They now have six points from their two games after a 1-0 win over Burundi in their first match on Saturday.
The top two nations in each of the six groups advance, along with the four best third-placed countries.
Nigeria dropped Captain John Mikel Obi, who played for Middlesbrough in 2018-19, but their side did include Brighton defender Leon Balogun, Stoke midfielder Peter Etebo, Leicester midfielder Wilfried Ndidi and Arsenal forward Alex Iwobi.
