Union de Douala president Franck Happi voiced confidence ahead of the club's Champions League round of 32 clash against Zmalek, saying he is sure that his side would beat Zamalek.
The Cameroonian side will host Zamalek on Sunday before playing the second leg one week later in Cairo.
"We are well prepared for Zamalek clash," Happi told Cameroon-info.net on Tuesday.
''We will have back all our players who missed the league game on Sunday.
"I am sure that we will beat Zamalek."
However, the club's president warned his players against conceding goals in the first leg to make the team's mission easier in the return.
"We will win with the highest possible score. But it will be important to win the game without leaking any goals," he added.
Zamalek are looking for their first continental title since 2002 when they lifted their fifth African Champions League trophy.
