The Super Eagles team have qualified for the 2022 Africa Cup of Nations in Cameroon after Lesotho and Sierra Leone played out a 0-0 draw Saturday.
The three-time African champions have eight points from four games, the Republic of Benin have seven points while the Leone Stars and the Crocodiles have four and three points, respectively, from five games.
Nigeria have now qualified for their 19th appearance in the continental showpiece with two games on hand prior to the game against Benin Saturday.
Nigeria had defeated Benin in Porto Novo, with a stoppage-time winner from second-half substitute Paul Onuachu.
The Nigerian side will then square off against Lesotho in their final Africa Cup of Nations qualifying game at Teslim Balogun Stadium in Lagos.
The Super Eagles finished third at the last edition of the continental tournament in Egypt, behind winners Algeria and Senegal but had emerged champions in 1980, 1994 and 2013, where they won the highly coveted trophy.
The West African side remain the team with the most bronze medal at the tournament, winning it eight times.
They will hope to clinch their fourth title at the 2022 edition of the Africa Cup of Nations in Cameroon.
