Watch the replays man. The ball comes in to Neymar waist high. Zuniga jumps knee first into Neymar's back. If you play football you clearly know that there is no reason to jump into a player's back with a waist high ball coming in from the other side of the player. I'm not even a Brazil fan at all, I think thy are over rated. If you think it was unintentional then you don't play much football or you didn't see it clearly...
