Arsenal’s Alex Iwobi scored as Nigeria beat Zambia 1-0 to become the first African side to seal a place at next year’s World Cup in Russia.
The win put them on an unassailable 13 points at the top of Group B.
Chances were missed at both ends by the time Shehu Abdullahi provided the cut-back for Iwobi to finish from inside the box in the 73rd minute.
Odion Ighalo, John Mikel Obi, Victor Moses and Moses Simon went close for the Super Eagles but failed to score.
Zambia goalkeeper Kennedy Mwenne produced an acrobatic save to deny Wilfred Ndidi in the second half in a pulsating end-to-end encounter.
