Zambia beat Algeria 1-0 in Constantine to move within three points of Group B leaders Nigeria in African World Cup qualifying.

The Zambians’ first victory in Algeria came after teenager Patson Daka lifted the ball home midway through the second half.

The visitors also had Kennedy Mweene to thank after the goalkeeper saved Riyad Mahrez’s first-half penalty.

Three months ago, 18-year-old Daka was one of Zambia’s star players as the team reached the quarter-finals of the Under-20 World Cup.

Meanwhile, Algeria – who performed creditably at the 2014 World Cup where they took champions Germany to extra-time – can no longer qualify for Russia next year.

The failure was greeted badly by some fans in Constantine, where the Desert Foxes missed several late chances.

They stay rooted to the bottom of the table with just one point and three defeats from their four games.
