I know it's part of the passion and the game, but why do players even bother remonstrating with the referee after a decision is given?
"Oh, OK, you've told me I'm wrong, good point... I've changed my mind, it's not a penalty"
It's not going to happen!
Saying that, it's nice to see this particular penalty overturned, but why wasn't Neymar booked for diving then?
