From Glasgow, Liverpool, Manchester and London, Rome to Rio and Buenos Aires – most cities have football clubs where derby day is the main event in the calendar for fans, publicans, pundits and police.

But some of the greatest football rivalries make no sense geographically.  Supporters of teams across the world look forward to travelling miles and miles just to earn the bragging rights for another season.

Cultural, as well as regional differences contribute to the fierceness of these clashes & performances of players in such matches decide whether they will be eternally loved or hated. A mistake or a moment of magic can create history, but can also result in brawls, fights, clashes & riots.

So, whatever the background to the biggest grudge matches, I’ve put together a list of 15 of the fiercest rivalries in world football.
