With Spain's finest set to do battle once again this weekend, we canvass opinion on whether any game in the world can match 'El Clasico'
Barcelona are preparing to face their bitter rivals Real Madrid in a crucial La Liga game this weekend at Camp Nou.
The Catalans go into the fixture four points behind their great rivals with just five more games left to play, and the destination of the title may well hinge on the result of the game.
Barcelona-Real Madrid is not the only great footballing rivalry around the world, though. The passion of the Boca Juniors and River Plate derby is a sight to see, whilst the myriad of historical and religious factors make Celtic vs Rangers a must-watch.
Across the globe, there is also the great Italian duel between Juventus and Inter Milan, while tempers, and the odd firework, are known to fray at Fenerbache vs Galatasaray.
Over in Germany, Borussia Dortmund and Schalke always provide a talking point or two, while the Penarol-Nacional and Paris St. Germain and Marseille fixtures are ones to keep on eye on in your calendar.
In England, the tensions of the Manchester United-Liverpool games always threaten to boil over, while the Tottenham and Arsenal north London derby is infamous for its animosity.
Of course, creating a poll such as this, we are always going to miss out the odd rivalry, which is why we invite you to post your comments below naming your favourite football rivalry and alternative suggestions.
