When Maurizio Sarri said last week that it might take two or three months for Chelsea to play the sort of football he wanted, the instant reaction was to raise an eyebrow and say: "Good luck with that."
This, after all, is not a club known for patience, and given the state of flux -- on the pitch and off it -- Chelsea find themselves in, Sarri has possibly the most difficult job in football.
In the 15 years since Roman Abramovich arrived at Stamford Bridge, Chelsea have made their way through nine permanent managers (if you count Jose Mourinho twice) and five caretakers (if you count Guus Hiddink twice).
