Owner Roman Abramovich's experiment to bring in an upcoming manager rather than the established names he had employed in the past failed for the same reason that proved the undoing of the Russian's other six appointments.
Trophies are the currency the West London club deal in and with Chelsea way off the Premier League pace in fifth and facing an imminent Champions League exit, the sacking many had forecast finally happened following a seventh league defeat on Saturday.
"When you come to Chelsea, you know one thing that you need [is] to bring results and show that the team is going the right way," Avram Grant, dismissed by Chelsea in 2008 after taking them to the Champions League final, told Sky Sports News.
