Chelsea Football Club /ˈtʃɛlsiː/ is an English football club based in Fulham, London. Founded in 1905, they play in the Premier League and have spent most of their history in the top tier of English football. Their home ground is the 41,837-seat Stamford Bridge stadium, where they have played since their establishment.
Chelsea had their first major success in 1955, when they won the league championship, and won various cup competitions during the 1960s, 1970s, 1990s and 2000s. The club has enjoyed its greatest period of success in the past two decades, winning 15 major trophies since 1997. Domestically, Chelsea have won four league titles, seven FA Cups, four League Cups and four FA Community Shields, while in continental competitions they have won two UEFA Cup Winners' Cups, one UEFA Super Cup, one UEFA Europa League and one UEFA Champions League. Chelsea are the only London club to win the UEFA Champions League, and one of four clubs, and the only British club, to have won all three main UEFA club competitions.
Chelsea's regular kit colours are royal blue shirts and shorts with white socks. The club's crest has been changed several times in attempts to re-brand the club and modernise its image. The current crest, featuring a ceremonial lion rampant regardant holding a staff, is a modification of the one introduced in the early 1950s. The club has sustained the fifth highest average all-time attendance in English football. Their average home gate for the 2012–13 season was 41,462, the sixth highest in the Premier League. Since July 2003, Chelsea have been owned by Russian billionaire Roman Abramovich. In April 2013 it was ranked by Forbes Magazine as the seventh most valuable football club in the world, at £588 million ($901 million), an increase of 18% from the previous year.
