Guinea and Gambia will be battling for a place in the quarterfinal of the 2021 Africa Cup of Nations on Monday at Kouekong Stadium in Bafoussam.
The Syli National booked their spot in the round of 16 courtesy of their second-place finish in Group B.
However, they lost their final group game, with first-half goals from Knowledge Musona and Kudakwashe Mahachi helping an already-eliminated Zimbabwe exit the tournament with a win.
Meanwhile, Gambia’s shock 1-0 victory over Tunisia on matchday three saw them finish second in Group F behind Mali to qualify for the knockout rounds for the first time.
Ablie Jallow scored the winning goal for the Gambians in the third minute of injury time.
A place in the last eight against either surprise package Comoros or hosts Cameroon awaits the winner of this tie.
Guinea will have to do without captain Naby Keita after the Liverpool midfielder picked up an injury time yellow card for foul language against Zimbabwe.
The two sides have clashed on 23 occasions in the past and Guinea have a superior record with seven wins to their name.
Gambia were victorious in four previous matches while seven games ended in a share of the spoils.
