There are so many aggressive defenders out there but when you're taking about the dirtiest and indisplined, it's got to be Sergio Ramos
He's one of the most fouled payers in football and has received numerous red cards. There was a time Sergio can't play five matches without getting a red card. Most times his tackles are not defensive but more of grudge or an attempt to bring down the opponent down
He tries everything possible to injure the key player of his opponent who sees to be a threat to him. Remember how he dislocated Mo Sala's arm and how he gave goalkeeper Karius elbow in his face during last Season's UCL final in Kiev?
He's made deliberate attempts to injure Messi during who pose to be threat to his team during El Classico and would act like it was an accident
Sergio Ramos remains one of my dirtiest and indisciplined defender out there
What about yours?
