"I take away some positives from this match. We created numerous chances. Now it's up to us to work on converting them into goals," Wissa expressed during the post-game press conference.
Kings Kangwa put Zambia in an early lead in the Ivorian coastal city of San-Pedro after Congolese goalkeeper Lionel Mpasi ventured out of his area.
However, Wissa, who has scored four goals in the English Premier League this season for Brentford, equalized from close range before the half-hour mark, and that's how it ended.
Wissa emphasized the crucial role played by coach Sébastien Desabre in shaping the team's tactics.
"He instills a lot of confidence in us, and we have the players to execute the style of play we present against the opposing defense," he added.
"The beautiful game serves no purpose if we don't score when we want to win. We gave our best, but we fell short. I'm confident we will improve," Wissa concluded.
