The ex-mailman has been in a good form than his current side and it was last month that he won his first cap with the national team. Otieno says his team was just unlucky against the 2009 champions but that has been rectified.
"Our match against them (Sofapaka), was not our best at all this season. We created many chances but did not take them, and we ended up conceding. It was not our day and it hurts that we lost, but it is football and it is bound to happen," Otieno told Goal.
"Our match against Posta Rangers will be a tough one for sure, but I am optimistic if we give our all, we will manage to collect maximum points."
Posta Rangers have started the season well and are currently on top with 17 points.
