Derbies: Derby della Capitale
Benito Mussolini was a man who usually got his own way. But when his hopes of building a single football team in Rome to take on the supremacy of the teams in northern Italy were scuppered by Lazio, who refused to join forces with three other local teams to form AS Roma in 1927, a rivalry was born. Since then, the Derby della Capitale has been punctuated by violence and riots. It's safe to say it remains the fiercest in Italy.
