Gabon lifts the curtain Saturday on the Africa Cup of Nations with the hosts, spearheaded by Pierre-Emerick Aubameyang, playing minnows Guinea-Bissau in the opening match in Libreville. It was there that Zambia beat the Ivory Coast on penalties in the 2012 final. Cameroon, four-time winners of the Cup of Nations but troubled by a raft of withdrawals of leading players, and Burkina Faso, the other teams in Group A, meet at the same venue at 1900 GMT.
