But Gradel fired the Elephants in front six minutes before half-time when he was ruled marginally onside as he ran onto Franck Kessie's superb lofted through-ball and fired across Kazapua.

And it was 2-0 just before the hour when Serey Die let fly from 35 yards and a deflection off defender Ryan Nyambe left the keeper helpless.

Wilfried Zaha, who had twice been denied clear penalties, sent a weak effort straight at Kazapua and Namibia cut the deficit when goalkeeper Sylvain Gbohouo cleared the ball straight to Joslin Kamatuka, who shimmied past Serge Kanon before finishing.

But Zaha and substitute Maxwel Cornet scored in the final 10 minutes to make victory safe for Ibrahim Kamara's side, who finish second after South Africa conceded a late winner to group champions Morocco.
