Chelsea are a club with a rich history and some great successes, both domestically and abroad.
In recent years, much of that success has been down to Roman Abramovich's millions, but it could not have been done without the talented managers who have led the team to glory.
Stamford Bridge has been home to some of the greatest managers in the world. So you can imagine how difficult it was to pick just 10 for this list.
For this reason, a certain methodology was used in these rankings.
Only the managers' time at Chelsea was considered. This means that someone like Luiz Filipe Scolari, who has a glittering resume that includes a World Cup from his time with Brazil, does not feature on this list. There are also no interim managers, so some Chelsea fans will be disappointed that Rafael Benitez is missing from the top 10.
Where two managers were close, preference was given to those with more trophies, but available resources were also considered, as well as the long-term impact that they had on the club. Trophies are also ranked according to importance. So a Premier League/First Division title holds more weight than the FA Cup, for example.
So without further ado, here are the top 10 Chelsea managers of all time.
