"We are coming into the match as underdogs, we are aware of the quality Mathare United has and that can work in our advantage.
"They are under pressure to win and that might make them to commit mistakes, and we are good at punishing when there is a chance.
"This is a match that we can win, we just have to stick to our game plan and ensure we do not give them a chance to play."
Omollo also confirmed he has a full squad to pick from the for the league match.
“We have no one out, it is a full house for us and that gives us an advantage of fielding the best team,” he added.
