Chelsea boss Andre Villas-Boas knows Blues fans could soon turn on him. AVB is not fooling himself that he will always have the backing of the supporters and is already steeling himself for more difficult times ahead.

Villas-Boas said: "I've never had it because I've only had a two-year career, but one day it will come. It is inevitable.

"Arsene Wenger went through it, Alex Ferguson went through it for sure and in the Latin countries you see these negative expressions from the supporters all the time after one poor result.

"The fans represent the values and sentiments of the club. They have the right to voice their opinions. Managers are always questioned by results. That's fair in a business where everyone wants to be successful.

"At Blackburn the public have shown a bit of disrespect for their manager. Steve Kean is my friend and I have high respect for what he's done.

"To be fair to Blackburn's owners, they have been sufficiently cool-minded to understand what's happening day to day and that knowledge is not always available to the fans."
