Egypt's in-form striker Ahmed 'Kouka' Hassan was on target again to help Olympiacos to a 2-0 Greek league victory over OFI Crete on Sunday, maintaining his impressive start to the season. Kouka broke the deadlock nine minutes after the break, heading home a cross from Mohamed Mady Camara. Giorgos Masouras wrapped up the win with ten minutes remaining as Olympiacos remained top with 16 points from six games. Kouka took his tally to four goals in the first six games of the season. He also netted a goal in the Champions League to give Olympiacos a 1-0 victory over Marseille in the group-stage opener last month. The 27-year-old will now link up with his Egypt teammates for a double header against Togo in the African Cup of Nations qualifiers. He will face competition from Zamalek's red-hot striker Mostafa Mohamed for a starting berth in the two games.
