Ivory Coast's ASEC Mimosas secured a vital 2-0 win over Tunisia's Esperance in the CAF Champions League Group B match on Sunday. The home side took the lead thanks to Bilel Yaken's own goal at the hour mark, before Ali Diallo rounded off the victory for the Ivoirians. ASEC reached seven points, but they will face holders Ahli in a tough confrontation in Cairo in their last game. Esperance have no hopes of reaching the semis as they lie bottom with four points.
