Former Chelsea boss Guus Hiddink says Roman Abramovich must stop sacking his managers.
Dutchman Hiddink was in the frame for the job after Carlo Ancelotti was axed but it went to the former Porto chief Andre Villas-Boas.
The former Blues caretaker boss said: "If you look at Manchester United, they are the example that clubs need stability. It is what Chelsea need too."
Hiddink, still pals with Abramovich after his four-month spell at Stamford Bridge in 2009, added: "Carlo did well for the last two years but, hopefully, this decision will now bring success for the future as well."
Asked if he had already told Abramovich to adopt a more sensible approach towards his managers, Hiddink declared: "Yes. I feel they're convinced now."
