Maurizio Sarri arrived at Chelsea promising fun and after a season of Antonio Conte's thunderous moods it was a message well received.
Eden Hazard perked up immediately as the campaign opened with an unbeaten run of 18 games in all competitions and there was even a time, albeit brief, when it seemed he might solve the Alvaro Morata puzzle.
There was lots to like about Sarriball and its eccentric creator, lost in his own world of tactical analysis, tobacco and superstition.
Then came the humbling at the hands of Tottenham in November and the impetus has faded, goals have dried up and the arm of Sarri's fun-o-meter swung back from the image of happy Hazard to the glum face of Morata.
Not a lot is wrong. Chelsea are tight at the back and can dominate in midfield, but at the very top not a lot needs to be wrong and losing twice to Spurs inside seven weeks at Wembley is no Chelsea fan's idea of a having a good time and the manager is searching for answers.
