Chelsea F.C., abbreviated as "Chelsea", was founded on March 10, 1905, nicknamed the "Blue Army". Its home ground is located at Stamford Bridge Stadium near the River Thames in Hammersmith Fulham, London, and it currently participates in the English Premier League.  
Roman Abramovich spent a huge amount of money on signings after acquiring Chelsea, and the team gradually became a powerhouse. The team is known for its rock solid defense and iron blooded spirit, as well as its overly defensive "shuttle bus" tactics, and is a representative team of defensive counterattack tactics in football. Chelsea has won a total of 6 English Premier League titles (1 in League One and 5 in the Premier League), 8 English FA Cup titles, 5 English League Cup titles, and 4 English Community Shield titles on the English stage. On the intercontinental stage, Chelsea has won 1 FIFA Club World Cup championship, 2 UEFA Cup Winners' Cup championships, 2 UEFA Super Cup championships, 2 UEFA Champions League championships, and 2 Europa League championships. In 2022, the Russo Ukrainian war forced Abramovich to sell the club, and a consortium led by Todd Burley and others took over Chelsea. On February 25, 2024, Chelsea lost 0-1 to Liverpool and won the runner up of the English League Cup.
