4. Barcelona v Real Madrid
Given it's widespread global popularity and the sheer passion it provokes from supporters everywhere, football has a seemingly endless list of passionate rivalries and derbies that could merit inclusion in such a countdown.
However, one that can certainly not be overlooked is the one between Spanish giants Barcelona and Real Madrid. Arguably the most famous, expensive and most eagerly-anticipated match in football, the rivalry between the La Liga title hopefuls has passionately raged for years.
Given that almost 315 miles separates the two cities, it has never been a case of local bragging rights. Rather, the fixture has traditionally pitted Spain v Catalonia.
