A shock-riddled Africa Cup of Nations in Ivory Coast has reached the round of 16 with four ties between winners of the competition highlighting a four-day schedule that kicks off on Saturday.
The clashes of champions pit Nigeria against Cameroon, Egypt against Democratic Republic of Congo, title-holders Senegal against Ivory Coast and Morocco against South Africa.
None of the other four matches feature a former winner, but 2015 semifinalists Equatorial Guinea will attract attention after topping a group including more fancied Nigeria and Ivory Coast.
Here, AFP Sport looks at the eight matches and predicts which countries will advance to the quarterfinals of the African football showpiece.
Saturday
Angola v Namibia
This clash of southern Africa neighbours was totally unexpected given Angola had not gone beyond the group stage since being 2010 hosts and Namibia had been winless in three earlier appearances.
Angola overshadowed Algeria and Burkina Faso to top Group D with Gelson Dala scoring twice while Namibia stunned Tunisia, were crushed by South Africa, then exceeded expectations to hold Mali.
Prediction: Angola to win

When it comes to finals in the Cup of Nations Cameroon have won all three against Nigeria, who got the better of the Indomitable Lions in three other meetings.

Prediction: Nigeria
