Koller promises to learn from Pyramids FC's previous failure in Lubumbashi.
During the group stage, Egyptian side Pyramids FC suffered a 3-0 defeat against TP Mazembe, finishing at the bottom of Group D.
The Red Devils are now determined to secure a clean sheet in Lubumbashi, setting the stage for a successful return leg in Cairo.
"I watched the TP Mazembe vs. Pyramids FC game, and while the latter missed several scoring chances, the hosts capitalized on theirs and achieved victory," Koller stated during the pre-game press conference on Friday.
"Tomorrow, we will do everything to produce a completely different outcome," added the Ahly coach.
Ahly advanced to the semifinals after a convincing 3-0 aggregate win over Tanzania's Simba SC in the quarterfinals, while TP Mazembe secured their spot by defeating Angola's Petro Atletico 2-1.
Koller emphasized that both teams are eager to reach the final and expressed confidence in his players' preparation for the challenging game.
"We are well aware of the difficult atmosphere, but our target is to achieve a positive result that will benefit us in the second leg," the 63-year-old Swiss coach said.
In a significant boost for Ahly, South African winger Percy Tau has been declared fit and available for the crucial CAF Champions League clash against TP Mazembe.
"Tau was dealing with a minor injury, but he has trained with the team for three days, and we are working on preparing him for the game," Koller added.
