Except Brazil looked really bad against Croatia - and what was particularly troubling was Brazil struggled to keep possession and to create out of the midfield (at least IMO).
Hulk is obviously a specimen, and he has a high work rate, but oddly enough - this Brazil team lacks some creativity outside of Neymar and Oscar. I think adding another offensive talent to the equation, while asking Marcelo and Dani Alves to perhaps pick their spots more selectively, would be ideal. If you're going to play Paulinho and Luis Gustavo together, which I don't disagree with, you need more up top, especially if Fred is at risk to be a non-factor for lack of service.
