#1 Ron Harris
Before the "Captain, Leader, Legend" John Terry, there was the "Chopper" Ron Harris.
His nickname was earned over 795 record-setting matches for the London club as Ron Harris (from Hackney) hacked at the opponent's and captained Chelsea to some of their most memorable moments of the 20th century.
His first trophy for the club was the 1965 League Cup over last year's surprising champions Leicester City. By that time, he had already forged a reputation as one of the league's most no-nonsense defenders. 2 years later, he was handed the armband to replace the departing Venables. He lost his first cup final (the 1967 FA Cup) as captain against Tottenham.
However, his irresistible presence alongside Chelsea greats like Peter Osgood & Bonetti ensured that in 3 years they were back - this time facing the dominant English superpower of the time, Leeds United. The 1970 FA Cup final was a direct face-off between the likes of Ron Harris & Billy Bremner - so it was no surprise that it turned into a brutal physical tie.
He played a crucial role in Chelsea's 2-1 victory; forcing the replay with an assist in the first tie and then crashing into influential playmaker Eddie Gray, leaving him much diminished just minutes into the game.
"Our manager Dave Sexton asked me to... leave my business card early on. After eight minutes I caught up with him... I thought I deserved a pat on my back for my part in Chelsea winning the cup that night," - On fouling Eddie Gray
