The intention of Kaka was hit the man, so the ref did good.
The Ivorian player actually was trying to hit Kaka , but Kaka saw him and he tried to protect , after that , the Ivorian player touched his head as Kaka hit him on the face, when he actually touched in the chest , it's in the videos , not in my imagination
Did he deserve the first yellow card ?: yes
Did he deserve the second one, therefore the red card? : not at all
Now Ivory Coast is definitely OUT, and we won't even have to tie to guarantee that!
