Mexican-based substitute Alain Nikong scored the only goal of the game on Thursday to send Cameroon into Sunday's final of the African Nations Cup with a 1-0 victory against Ghana, a sports analyst of DPA reported from Ghana. However, Cameroon coach Otto Pfister will be disappointed with the sending-off of Andre Bikey in injury time after he pushed over a medical official, who was trying to hurry an injured Cameroon player off the field, he said. As Bikey tried to leave the field, he was met with a barrage of water bottles thrown from the stands. Surprisingly, the 46,000 seater Ohene Djan stadium was not filled to capacity, with some 12,000 seats empty at the start of the game. Although many of them filled during the course of the first half at least 3,000 empty seats remained. Ghana coach Claude le Roy had to substitute winger Laryea Kingston, who injured his ankle during the warm-up. In his place Abedi Pele's son Andre Ayew came in to the side for his first start of the tournament. The Frenchman also had to replace suspended captain John Mensah, taking Chelsea midfielder Michael Essien into the backline instead and giving him the captains' armband. The first chance of the game fell to the Black Stars in the fifth minute as Sulley Muntari's free-kick floated through the Cameroon goalmouth, only for Eric Addo just failing to connect with the ball. Ayew had the next chance on 27 minutes after being set up by Quincy Owusu-Abeyie, but the Olympique Marseille forward who went around two defenders, shot too weak to really trouble Idriss Kameni.
