No to both.
Italy rarely trounce teams, it's just not their style. The bet here is Italy to win by a 1 goal margin +340. They'll get the goal they need, sit back and defend it like their lives depended on it. There is no benefit to be gained from trying to batter Slovakia.
As for NZ... I think their luck is about to run out. Paraguay are clearly the class of this group and I fancy them to win by a couple tonight.
