Antonio Conte's future as Chelsea boss was cast into further doubt as his 10 men were thrashed 4-1 by Watford on Monday night.
The Blues, who lost 3-0 at home to Bournemouth last week, were poor again at Vicarage Road and had Tiemoue Bakayoko sent off inside half an hour.
Troy Deeney scored a penalty in the closing stages of the first half but Chelsea stayed in the contest and equalised through a magnificent Eden Hazard goal.
The visitors were not level for long, however, as Daryl Janmaat scored his own memorable effort to put Watford back in front before Gerard Deulofeu, man of the match on his home debut, and substitute Roberto Pereyra rounded off the win with breakaway goals to secure an emphatic win.
Conte had called on Chelsea's hierarchy to "prepare a statement...to say they trust me in my work" ahead of the game but it was another dismal evening for the defending champions, who are now 19 points adrift of leaders Manchester City.
