Qualification ties were played on a home-and-away two-legged basis. If the aggregate score was tied after the second leg, the away goals rule would be applied, and if still level, extra time would be played. The away goals rule would again be applied after extra time, and if still level, the penalty shoot-out would be used to determine the winner.[3]
The two winners of the fourth round qualified for the Olympic football tournament.
Schedule
The schedule of the qualifying rounds was as follows.[4]
Note: Liberia, Mali and Tunisia withdrew.[6][7] Liberia because of administrative reasons, due to Ebola outbreak (initially to play home match in Cameroon).[8] Nigeria versus Mali and Liberia versus Cameroon were to be played in early/mid-May so Nigeria and Cameroon were able to leave earlier for the World Cup.[9][10]
Note: Zimbabwe failed to secure the necessary funds to travel for the first leg, and FIFA awarded the match 3–0 to Ivory Coast.[11] It was initially indicated by the CAF that Ivory Coast won the tie and the second leg was cancelled,[12][13] but this was overturned by FIFA. Ivory Coast then failed to show up for the original second leg, but they were not punished, and the second leg was rescheduled.[14][15] Ivory Coast then withdrew from the tie before the rescheduled second leg.[16]
