Clásico Tapatío Atlas' fierce rivals are Guadalajara city-rivals C.D. Guadalajara, known as Chivas. The derby is known as the Clásico Tapatío and is said to be the oldest football derby in Mexico, dating back to 1916. The first match between the two sides was a friendly that took place shortly after Atlas were founded, the game ended 0–0. The first competitive match between the two sides came in the 1917 "Torneo de Primavera", which translates into English as the "Tournament of Spring". Atlas were victorious this time round, winning 2–1. The game sparked controversy, however, when complaints of a bad refereeing performance were put forward by Chivas. Chivas were so angered by the result, that they refused to play in the next "Liga Amateur de Jalisco" tournament of 1917–18, unless the president of refereeing, Justo García Godoy, resigned from his position; when Godoy failed to do so, Chivas refused to join the tournament. Chivas are the most victorious in Guadalajara derbies, however, winning 16 of 35 competitive fixtures the two sides have played. Atlas have only won 9 and the sides have drawn 8 times.
