Club Atlético de Madrid is a Spanish football club based in Madrid who play in the Primera División of La Liga. Their home stadium is the Vicente Calderón Stadium, which currently holds up to 55,000 spectators. The club is one of the most successful in Spanish League history, having won both La Liga and the Copa del Rey on nine occasions, including a double in 1996. They also won the European Cup Winners Cup in 1962 and were European Cup runners-up and Intercontinental Cup winners in 1974.
During their history, the club have been known by a number of nicknames including los colchoneros or the mattresses due to their first team stripes being the same colours as old-fashioned mattresses. During the 1970s they became known as los indios. This was allegedly due to the club signing several South American players after the restrictions on signing foreign players was lifted. However there are a number of counter theories which claim they were so named because their stadium is camped on the river bank or because los indios were the traditional enemy of los blancos - the whites. The latter nickname refers to the club's city rival Real Madrid.
