In the CC, Neymar was more towards the left, while Oscar played in the middle more often than not. However, in the world cup its been Hulk-Neymar-Oscar. When Oscar played in the middle for Brazil against Croatia in the second half, Brazil defensively were getting worked on the wings and Scolari reverted back to Neymar in the middle. I don't know if its Scolari or the brazil federation that tells Scolari to make sure Neymar is the focal point of Brazil...
