Well, while they were both flops, Pablo Garcia and Thoms Gravesen both played for Real Madrid, and their only purpose is to be thugs.
You have Madrid legend Camacho, who is today known as a fatass manager but as a player was famous for being a ruthless hardman, and more recently Salgado was pretty damn violent.
Pepe isn't even the dirtiest player in the world right now, he's a fucking psychopath sure but he's never done any individual act as disgusting as some of De Jong's antics, and the likes of Carvalho and Lucio just off the top of my head can be just as dirty, not to mention teams like Stoke where half the lineup is hatchetmen. And don't forget Barca legend Van Bommel.
Pepe is a cunt but talk about hyperbole, the only way he's different from say Carvalho is he has worse judgement.
