Maurizio Sarri's job is on the line after Chelsea were humiliated by Bournemouth, losing by a four-goal margin for only the second time in Premier League history.
The other time was against Liverpool in 1996, before the Roman Abramovich era began, and Sarri admitted afterwards that he cannot motivate these players.
Why? What is it that allows Chelsea's form to fall off a cliff under certain managers? Does player power exist? Or is it the coach's fault? Here, Sportsmail analyses the situation.
