Crusaders - PSNI Football prediction

Crusaders are definitely the best team in Northern Ireland. This match should be an easy one for them, but you never know.
So far, Crusaders have 2-1-1 score (lost was against Linfield, so no hard feelings there, but it was at home, hmmm...). Anyway, they are great team that play attacking football and their matches are always exciting.
PSNI on the other hand started really bad. 3 lost matches in a row are not looking good and they will try to stop that...there is better way but to do that in champion's home field. They will probably start brave because they have nothing to lose here and if they shock their host, that will be their chance.
Crusaders are much better team here and what I really expect here is to demolish their visitors. I believe they can score 2 goals in first half already.
