Here Press Association Sport looks at how five more Blues made themselves club greats.
Scored 132 goals in 169 appearances for Chelsea, with 13 hat-tricks which included three hauls of five and three of four. Greaves was sold to AC Milan against his wishes after missing out on a trophy during his four-year spell as a Blue.
'The Cat' made 729 appearances as Chelsea's goalkeeper, having made his debut in March 1960 at the age of just 18 and inevitably keeping a clean sheet. It was the first of 208 shut-outs he achieved with the club. A key figure in the successful team of the 1960s and 1970s.
'Chopper' Harris holds the club record of 795 appearances and was a first-team regular for 18 years. He was the first Chelsea captain to lift the FA Cup and the first to lift a European trophy, the 1971 Cup Winners' Cup.
Blessed with grace and skill to make many top players envious, Osgood was the star of the team in the 1960s and 1970s. He scored in every round of the 1970 FA Cup. In all, he scored 150 times for Chelsea, over two spells. He died in 2006, aged 59.
The Italian forward helped Chelsea to four trophies in seven seasons. He scored 80 goals in 312 games, including the winner in the 1998 European Cup Winners' Cup final. In 2003 he was voted the club's greatest ever player in a poll on the club's website.
