After a surprising Qualifiers campaign, in which they beat former champion and medal contender Senegal, Guinea finished the regional play-off tied with Mali (3–3) in second place, but the Guineans fell short of automatic qualification for the Final Round due to a lower goal-average.
Senegal and Mali secured automatic, Cape Verde was eliminated, but Guinea was awarded a wild card – along with Rwanda.
Joining Mansare as Guinea central players, were power forward Ousmane Dramé, who contributed 8.2 rebounds in six games, and guard Ahmed Doumbia.
Ahmed Doumbia only played the last three games of the Qualifiers, but he was immense for Guinea, averaging 13 points and 5.7 assists.
This was accomplished under the Serbian head coach Željko Zečević who replaced Frenchman Michel Perrin at the helm ahead of the decisive last window of the Qualifiers in February 2021.
Some of his coaching highlights in African included a Second-Place in the 2019 FIBA AfroLeague at the helm of Morocco's AS Sale.
Guinea has played at the AfroBasket (formerly the FIBA Africa Championship) six times, with its first appearance during the inaugural season in 1962.
