El Superclásico: Boca Juniors vs River Plate
Boca and River are Argentina's biggest football clubs and they have dominated the national championship for the last 70 years. More than half of the country's football fans support one of these clubs. Both clubs formed in a Buenos Aires area called the La Boca, but in 1938 River Plate earned their 'millionaires' nickname after moving to the affluent Nunez neighbourhood. The rivalry is more about class and money, with River Plate's support traditionally coming from the high-fliers in the Buenos Aires society. And the Boca supporters tend to come from the working classes and migrant communities.
