I don't believe it was a penalty, a clear dive. Should have been to a yellow to Fred for simulation
However the defender shouldn't have a complaint, his hand/arm shouldn't have been there in the first place!
Neymar should have seen red for the elbow, if you watch the replay, a second or two before it happens, he's watching the Croatia player and knows where his own elbow is. Straight red and a different game entirely
Also, I don't see what the problem was with the Croatias second goal, the Croatian player went in for the ball, pardon my ignorance, but I didn't see anything wrong with it at all.
Brazil were probably the better team on the day though, I thought the score line was a bit flattering. Should have been a one goal difference, if not a draw.
Should they (Brazil) play like that out of the group, they may be in trouble. They will most likely play Spain or the Netherlands in the round of 16
Will be interesting to see which team gets out along with Brazil
