It was Ibenegbu's goal struck from all of 30 yards that sealed the win for the Seasiders in a thrilling match inside the Omnisport Stadium in Douala.
However, Ibenegbu, who completed an off-season move from Heartland to Warri Wolves in January, expressed happiness to score the winning goal on his debut game.
"I feel so happy to score in my first game and the winning goal for that matter. I thank God for He made it possible. Kudos to my teammates because it wasn't an easy game," said the midfielder to supersport.com.
But the former El-Kanemi Warriors man knows that the win in Douala is just one leg of their first round clash in Africa's second tier club competition.
He is rallying his teammates to be at their best against Union Douala in the decisive leg at the Warri City Stadium on March 9.
"It is good we won the first leg away and definitely it makes our job in the return leg a lot more easy if we go by the result. But in football such counts for nothing as there's still a second leg to play for.
"So we will have to be at our best if we want to progress into the next round because we still have 90 minutes to play," said Ibenegbu, who is nicknamed Mosquito.
If Warri Wolves overpower Union Douala in the first round of the Caf Confederation Cup, they will go up against either Angola's Desportivo da Huila or 2013 Tunisian Cup winners, CA Bizertin in the next round.
The contingent of Wolves are expected to return to Nigeria this week.
