Super Eagles head coach, Jose Peseiro says his side must now start scoring goals if they want to achieve their objective of winning the 2023 Africa Cup of Nations.
The Super Eagles scored a paltry three goals, two from open play and one penalty in the group stage.
They wasted a number of clear cut chances, especially in their opening two games of the competition.
Having booked their place in the Round of 16, Peseiro expects things to get more difficult in the competition.
“It’s a new competition that’s starting for us. The most important part of a competition, the knockout matches.
“We will have to be more clinical in front of goal because the slightest mistake will be fatal for us,” he said.
The Super Eagles will take on the second-place team in Group C in the Round of 16 at the Felix Houphouet Boigny Stadium on Saturday night.
