Andre Ayew scored a penalty as Ghana beat Uganda on Tuesday in a lacklustre opening to the four-time champions' bid for a first African Cup of Nations title in 35 years. The West Ham winger netted in the 32nd minute of the Group D game after Asamoah Gyan was held back by Isaac Isinde in the penalty area in Port-Gentil. Avram Grant, a former Chelsea manager, is looking to lead Ghana to a second successive final but go better than 2015 when his team lost to Ivory Coast.
