Club de Futbol Cruz Azul or simply Cruz Azul is a professional football club based in Mexico City, Mexico. It competes in the Liga MX, the top division of Mexican football. Because "azul" means "blue" in Spanish, the club has traditionally worn a blue home kit. After 22 years the team returned to the Azteca at the conclusion of the 2017-18 Liga MX season. Cruz Azul has been in the Primera División champion nine 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.
