Despite being the underdogs, it was the Super Eagles who reigned supreme, thanks to William Troost-Ekong's spectacular penalty.
Stalemate at the half-time break
As expected, both teams came out all guns blazing, with the defences trying to keep each other in check. Although the first half ended goalless, there was plenty of action, as both teams registered at least six shots.
The Ivorians had most of the ball in the first half (60% possession), three of their six shots went on target, but Chippa United's Stanley Nwabali made some fine saves, denying them their first goal.
On the other hand, the Super Eagles lacked efficiency in front of goal. While they had more shots (7) than the Elephants, none of those shots went on target.
Peseiro's side also won the set-piece battle, as Nigeria had five corners to Ivory Coast's two.
Troost-Ekong nets the winner for Super Eagles
The Super Eagles' fortunes improved in the second half. Just a few minutes into the half, Ousmane Diomande fouled Napoli's Victor in the penalty box.
Of course, this had to be checked by VAR, and after a couple of minutes, the Super Eagles were awarded the penalty. Calm and composed, Nigeria's captain Troost-Ekong converted from the spot.
The PAOK defender has now scored in three consecutive AFCON events. He's Nigeria's top-scoring defender in this competition.
The Ivorians tried – to no avail – to get back on level terms. The Super Eagles' defence proved to be too much for them, as none of Ivory Coast's seven second-half shots went on target.
The Super Eagles claimed all three points in a tightly-contested fixture, a well-deserved victory.
