Katongo's goal earns progress from group stages
Zambia booked a place in the last eight of the Africa Cup of Nations with a 1-0 victory over co-hosts Equatorial Guinea.
Equatorial Guinea had already qualified, but the defeat left them facing a probable match against the highly-fancied Ivory Coast.
Christopher Katongo scored the only goal of a tight match midway through the second half to ensure Zambia finished top of Group A with seven points, pushing Equatorial Guinea into second.
Zambia will face the Group B runners-up in their quarter-final in Bata while Equatorial Guinea will meet the winners in Malabo.
Ivory Coast currently lead Group B and need a point against Angola on Monday to finish top.
Clever
For the first time in the tournament, the co-hosts included a locally-born player in their starting line-up as Jose Bokung was picked at left-back.
Equatorial Guinea's team is made up of Spanish-born players who qualify through their parents and naturalised players from other countries including Brazil, Nigeria and Cameroon.
The hosts had the best chance of the first half when Ivan Bolado cleverly worked an opening, but was denied by Kennedy Mweene's last-ditch challenge.
Zambia broke the deadlock on 67 when China-based Katongo collected the ball from a throw-in and scored with a low shot from the edge of the penalty area which went just inside the near post.
Equatorial Guinea came close to a rapid equaliser when captain Juvenal Edjogo curled a free kick just past the post.
