Luis Suarez has done it again for the third time he has bitten an opponent and this time on the biggest stage in the world. Why does he do it? What goes on in his mind? It seemed like Suarez had left behind his biting ways after the Branislav Ivanovic incident in a Premier League match but here he's done it again sinking his teeth into the shoulders of Italian defender Giorgio Chiellini which was followed by him going down actually holding his teeth. It seemed like this phase was over that he had learned his lesson and moved on.
