The Syli National displayed some grit to win the match at the Reunification Stadium in Douala to win the bronze medal of the tournament designed exclusively for home-based players.
Talented Guinea playmaker Morlaye Sylla put his side in an early lead before with striker Mamadouba Camara doubling the advantage on the stroke of half-time.
A second-half impressive display by the Indomitable Lions did not lead into goals which resulted in the West Africans picking the third place of the competition.
Sylla, the talented Guinea playmaker, put the Syli National in the lead in the ninth minute when the AC Horaya split the home side’s defence with his dexterity before firing past goalkeeper Haschou Kerrido.
