Deportivo Saprissa is a Costa Rican sports club, mostly known for its football team. The club is based in San Juan de Tibás, San José, and play their home games at the Estadio Ricardo Saprissa Aymá. The colours are purple (burgundy) and white. It is the main team representing the capital, but with the distinction of being massively followed throughout the whole country and overseas. The club was founded in 1935 and has competed in the Costa Rican first division since 1949. The name of the team comes from one of the club's main founders, Ricardo Saprissa Aymá. One of the most popular nicknames for the team El Monstruo Morado can be traced back to 1987, when the Costa Rican newspaper Diario Extra gave the team the nickname during a derby, because of the club's enormous following. A reporter commented that the sea of fans in the stands at the Estadio Ricardo Saprissa Aymá in Tibás wearing purple, and the tremendous noise they were generating, made him feel like he was "in the presence of a thousand headed monster". Saprissa immediately adopted the nickname El Monstruo Morado. It remains the most lauded football team in the whole region.
