Chelsea were formed in 1905 and were elected into the Second Division of the Football League. They just missed out on silverware 10 years later with an FA Cup final defeat. The Blues had to wait for their first major trophy in 1955, when under manager Ted Drake, they won the league title. Chelsea claimed the League Cup for the first time in 1965 and were defeated in the FA Cup final two years later.
Featuring the likes of Ron 'Chopper' Harris, Ian Hutchison and Peter Osgood, Chelsea overcame Leeds to win the FA Cup in 1970. In the following season, they clinched the European Cup Winners' Cup with a replay victory over Real Madrid.
Financial problems meant the Stamford Bridge club dropped into the Second Division, and at one point they were close to falling to the Third Division.
They eventually won their place back in the top flight in 1984, but their stay only lasted four seasons. They clawed their way back to the First Division again as Second Division champions in 1989 and have remained in the top flight ever since.
