FRANCEVILLE, Gabon — Ghana is on the verge of the quarterfinals at the African Cup of Nations, but its one remaining obstacle in Group D is a Guinea team which is desperate to reach the knockout stage and preparing for its last group game like it was a final.

Ghana's victories over Botswana and Mali have put it within a point of being certain of qualifying as group winner, while Guinea and Mali — who are equal on three points — both have a chance of going through.

With Mali expected to beat Botswana in the other Group D match, Guinea knows it likely has to pull off a shock against Ghana at Stade de Franceville on Wednesday to have a chance.

Guinea coach Michel Dussuyer says "against Ghana it will be like a final. We have respect for them but we want to win."
