Barcelona and Real Madrid
It’s quite possible that this is the premier rivalry when it comes to professional football- anywhere. This is the battle between two of the most historically successful clubs who also happen to have fat wallets. It’s like, a team of Crosbys vs a team of Ovechkins in the NHL. The fans? Well, they’re just as passionate as you would expect. Although there certainly is a history of violence between the fans of the two clubs, the majority of the ‘fuck arounds’ come in the form of mind games. Vandalized team busses, interrupted practices, threats, chants, and in one instance, a pig head being thrown onto the field.
