Nigeria are on course to take a big step towards qualification for the 2018 FIFA World Cup after Moses Simon put the Super Eagles ahead 1-0 against Cameroon in Yaounde.
The KAA Gent forward was on-hand to beat Fabrice Ondoa from close range after Odion Jude Ighalo made a good run from the right.
However, the Cameroonians may feel that they were unlucky not to have taken the lead earlier in proceedings.
Eagles goalkeeper Ikechukwu Ezenwa denied Andre Frank Zambo and Benjamin Moukanjo.
Nigeria, though, looked far better and had some joy attacking down the left-hand side where Victor Moses demonstrated skills and pace.
The Super Eagles almost put daylight between themselves and Cameroon when Victor Moses worked himself some space, but his low drive failed to beat Ondoa at his near post.
Cameroon had a great chance to equalise when Moukanju pulled the ball back to , but he failed to get his body over the shot and skied his effort.
