The Roman Abramovich era at Chelsea is over following the announcement that the consortium led by Todd Boehly will be allowed to buy the club. Chelsea enjoyed unprecedented success with Abramovich at the helm, but which of the 13 managers he employed fared best and worst?
The most illustrious and successful of those 13 in terms of pure numbers of trophies is Jose Mourinho. But somewhat surprisingly, teh Portuguese tactician does not come out on top when compared to the other 12 by their points per game.
Mourinho does make the top two, though, and is followed by two more Chelsea bosses who won Premier League titles at Stamford Bridge. The most recent incumbent, Thomas Tuchel, comes just a bit lower than those three league champion managers in sixth.
Tuchel's record marks a serious upturn in fortunes from his predecessor Frank Lampard, who does not fare well at all here. In fairness, Lampard did have to contend with a transfer ban, but his legend will live on at the Bridge more for his achievements on the pitch in his playing pomp than off it as a manager.
How do all 13 permanent head coaches appointed by Abramovich compare, though? We've had a look at their records in the Premier League for the Blues and worked out their average points per game based on those results.
Here's how each Chelsea manager of the Abramovich ranks. Where tied on points per game, we have ranked them by their win rate. You might be surprised by a few of the positions…
