CHELSEA UNDER ROMAN ABRAMOVICH DID THIS>

 Roman Abramovich ruled Chelsea  for a period of 19 years.

 In those  nineteen years Chelsea won  21, twenty one trophies.

He also had 13  thirteen different managers. Far to many I would say  for almost one manager a year.

 And Jose Mourinho and Guss Hiddink had two spells at Chelsea.
