Very shortly this time as in my papers this is very clear:
Oulu are class-wise bottom-3 club who have been riding their luck lately. The HJK win was a good example of that and they needed a lot of luck and even help from the referee in form of a red card.
KuPS huge run of games without a loss was cut short last time away at strong Honka. It had to happen some day, but they remain a top-2 team in this league by any metrics.
Last mutual games are 5 straight wins for KuPS without conceding a goal. The first encounter at Oulu ended 0-3 after total KuPS domination.
KuPS miss only two long-term absentees.
Oulu are about the same strenght than vs HJK, there are absentees and this is 3rd match in a row away in a week. Rough schedule and there is not enough depth for that. Last week they also lost in the cup to a lower league team and they are very vulnerable.
