River Plate and Boca Juniors are the two most successful teams in Argentina and the two best supported. This manifests itself as one of the fiercest rivalries in world football. When they play it is known as the Superclásico. The Observer newspaper in England put the Superclásico at the top of their list of "50 sporting things you must do before you die", writing that "Derby day in Buenos Aires makes the Old Firm game look like a primary school kick-about."
