Roman invested money and hired people to work on the football side of thing, Including the manager. If you were going by your work and your boss kept interfering and putting you under pressure, A few will work better, and the majority will start getting nervous and make mistakes. The fact is that if Roman really wants his money to be invested well, He has to stop sacking, hiring and sacking, I haven't checked but I'd imagine we've gone through more managers than any other team in the Premiership at the moment. We need a long term a manager, alot that Carlo was that long term manager, but for Chelsea I'd like to see Villa-Boas, as he's young, and he can stay at Chelsea for 10-15 years, and make us into one of the greatest teams of all time.
