Until the appointment of Ruud Gullit as player-manager in 1996, Chelsea was a relatively unknown team in the Premier League. However, real success washed ashore only after the appointment of the eccentric Jose Mourinho, who led Chelsea to two back-to-back titles along with other silverware.
Chelsea have always managed to finish in the top 7 since 1995, until in 2015-16, when the defending champions were languishing at 16th in December, before somehow managing to jump up 6 positions to finish 10th.
