"PALMEIRAS v CORINTHIANS -- Sao Paulo, Brazil Another derby that has been going for nearly 100 years. Corinthians used to be the only club in the city, but a group of Italian members broke away to form Palmeiras, earning the nickname of the "betrayers" by Corinthians fans. Morumbi is the biggest stadium in Sao Paulo and all the derbies are played there, although the Pacaembu stadium, which hosts many Corinthians matches, is also used for the occasion." ?
