FIFA will have to think hard about who they assign to referee the Brazil matches. No doubt the crowd intimidated the referee in the Brazil-Croatia match and that had a major impact. Those crowds are passionate and into it, and it will take a strong official to resist giving in to the intimidation.
Croatia should be done better to challenge a jittery Brazil in the first half. There was space to exploit on the wings.
For this game, Julio Cesar looked very shaky and that may be an issue in later rounds.
It is going to be very hard to beat Brazil on their own soil.
