Zambia have beaten already-qualified Equatorial Guinea 1-0 in the African Cup of Nations to secure first place in Group A and join the co-host in the quarter-finals.

Christopher Katongo scored the winning goal in the 67th minute on Sunday at the Nuevo Estadio de Malabo as Equatorial Guinea’s unexpected run of two opening victories ended.

The result means unbeaten Zambia top the group, while Equatorial Guinea finish in second place and will face a likely meeting with cup favourite Ivory Coast in the last eight.

The scoreline also eliminated Libya despite a 2-1 win against Senegal. Libya needed Equatorial Guinea to beat Zambia to have any chance of progressing.
