The Lions of Teranga had already clinched a place in the knockout phase before this final Group C game in Ivorian capital Yamoussoukro, and Maccabi Haifa defender Abdoulaye Seck came into the starting line-up to head in the opener from a free-kick just after the hour mark.
Iliman Ndiaye of Marseille then came off the bench to make it 2-0 in the 90th minute, as Senegal ensured that they will be the only team to take nine points out of a possible nine in the group stage.
They will stay in Yamoussoukro for a last-16 tie next Monday against one of the best third-placed teams, and there is a good chance they will end up playing hosts Ivory Coast who remain in contention to qualify despite coming third in Group A.
Cameroon's remarkable comeback to beat Gambia 3-2 in the other Group C game in Bouake relegated Guinea to third place on goals scored, but the Syli National already know they will be one of the best third-placed finishers.
They were also boosted here by the return of Serhou Guirassy, after the striker who has been in prolific form in the German Bundesliga this season with VfB Stuttgart missed their opening two group matches.
