Niyonzima Seif's strike and an own goal by Andrew Juma gave the hosts the victory while the goal for the Green Army was scored by Kenneth Muguna. The Posta Rangers coach is optimistic the Muguna strike can take the Kenyan giants to the second round of the annual competition.
"We are all motivated with the result and an away goal we scored in Kigali last weekend. And with what I have seen in the team so far, I believe we can qualify to the next round," Omollo said ahead of Saturday's game.
The 51-year-old will also have Benson Omalla back, who was on duty for Kenya's Rising Stars, and the tactician has pointed out what the youngster is expected to bring in the team.
"We know how important that match is to us and the good thing is that Benson Omala is back in the team," Omollo continued.
"We all know what the youngster can bring to the team; energy and lethality. He will be key for us tomorrow.
"But we need to have a top-class defending and make good use of our chances. When we played in Kigali, we looked dangerous and created several chances and I believe tomorrow will not be different.
"If we do the right things tomorrow we will win the match."
