Antonio Conte asked for a vote of confidence from the Chelsea hierarchy but this crushing result sent out its own message: they are in a desperate fight to finish in the top four and with that status is in danger so is the head coach.
Watford deserved this win, the first since they sacked Marco Silva, which pushes them six points clear of relegation and while Conte will point to the first-half dismissal of Tiemoue Bakayoko as crucial he also knows they simply did not play well enough. Not for a team with their aspirations and expectations.
The visiting fans sang their support for Conte but it is the board and owner Roman Abramovich who matter and while there is an expectation that the Italian will leave at the end of this season he is risking that happening sooner should he fail to deliver Champions League football. That looming last-16 tie against Barcelona appears ever more crucial. If Conte lasts that long.
