Luis Suarez lived through his worst moment with Georgio Chiellini in the 2014 World Cup, when he bit the Italian defender.
Chiellini has published a book speaking about his career and in it he mentions Suarez.
"I admire his malice, if he loses it he becomes a normal striker. Nothing strange happened that day in the 2014 World Cup. I marked Cavani most of the game, another difficult player. I realised he had bitten my shoulder. It happened, but this is his strategy of contact in the body to body fight and I can say it, it's mine too.
"He and I are equals and I like to face attackers like him. I called him a couple of days later but there was no need to apologise. I'm also a big son of a bitch on the pitch and I'm proud of it. Malice is part of football. To beat an opponent you have to be intelligent."
