Club Deportivo Social y Cultural Cruz Azul Asociación S.A. de C.V. or simply Cruz Azul (pronounced [kɾus a'sul]) is a professional football club based in Mexico City, Mexico. It competes in the Liga MX, the top division of Mexican football. Originally from Jasso, Hidalgo the club moved to Mexico City in 1971. Estadio Azteca, the nation's largest sports venue, served as their home venue until 1996, when they moved to the Estadio Azul. After 22 years the team returned to the Azteca at the conclusion of the 2017-18 Liga MX season. Its headquarters are in La Noria, a suburb within Xochimilco in the southern part of Mexico City. Cruz Azul has been the Primera División champion eight times, trailing Toluca's 10, C.D. Guadalajara's 12, and Club América's 13. Cruz Azul's six titles makes it the second-most successful club in the history of the CONCACAF Champions League, the most prestigious international club competition in North American football, trailing intracity rival Club America. Cruz Azul was also the first CONCACAF team to reach the final of the Copa Libertadores, the most prestigious club competition in South American football (which invited top Liga MX clubs from 1998 to 2017), losing on penalties to Argentine football giants Boca Juniors in 2001. In the 1968–69 season, Cruz Azul was the first CONCACAF club (and third worldwide) to complete a rare Continental Treble, winning the Mexican Primera División championship, the Copa México national tournament, and the CONCACAF Champions League.
