West African neighbours Mali and Guinea will clash in Mongomo in search of a quarter-final ticket.
Both have impressed observers with their displays so far, although Mali have twice failed to see out leads in their games while Guinea could live to regret not seeing off the Ivory Coast after leading and having a one-man advantage.
Nevertheless, winger Ibrahima Traore, who scored against Cameroon at the weekend and has been one of the players of the tournament so far, said: “We are progressing. We have played against two of the tournament favourites and nobody expected us to take anything from them.
“It’s not over, we have a final to come and we’ll do everything to get the three points.”
Guinea coach Michel Dussuyer has defensive problems, however, with a calf problem having kept captain Kamil Zayatte on the sidelines so far while Florentin Pogba came off against Cameroon with a groin injury.
Germain Berthe is set to start in goal for Mali after Soumaila Diakite was ruled out for the rest of the competition with the groin injury that forced him off against the Ivorians.
