I don't know how to deal with this matchup, so I'll go combo. It makes sense for the double, it makes sense for OSFP to be in attack, therefore it makes sense in both halves to win from two corners. I don't think in the first half the phase in the corners will escape and we have 7 and finally I don't think we have a basketball score and see more than 5 goals. Okay, there will be some dignity.
