If noise surrounding Antonio Conte's future wasn't loud following a 3-0 defeat to Bournemouth at home last week, then it certainly will be after Chelsea lost 4-1 to Watford at Vicarage Road on Monday night.
Tiemoue Bakayoko capped off an insipid start to the game when he received two yellow cards in the space of five minutes, debilitating his teammates by leaving them a man down with just 30 minutes played.
It went from bad to worse for Conte's men when Troy Deeney converted from the penalty spot three minutes before half-time.
Deeney was handed the opportunity after Thibaut Courtois fouled Gerard Deulofeu in the box.
New signing Olivier Giroud made his debut when he replaced Pedro with just over 25 minutes to play.
But it was Eden Hazard who produced a moment of magic to bring Chelsea back into the game.
The Belgian superstar opened up space for himself 25 yards from goal before bending a superb strike past Orestis Karnezis.
The scoreline lasted just two minutes before the Hornets produced an avalanche to seal an unexpected victory.
Pereyra put the game to bed and compounded Chelsea's horror night with a sublime strike in stoppage-time.
