Watford put in a dominant display from start to finish as they netted four times against Chelsea's Belgium keeper. The Blues looked like they may have salvaged a draw when Eden Hazard equalised in the 82nd minute. However, the home side hit back instantly with three goals in quick succession to earn themselves a deserved victory.
Watford started the game brightly, creating multiple chances in the first ten minutes. Gerard Deulofeu and Richarlison were both causing Chelsea problems and it looked like the Hornets would go ahead when Troy Deeney was left free at the far post for a Watford corner, but the striker miss hit the ball and it flew wide.
Chelsea had their first chance in the 12th minute when Willian shot over. But it was the home side that continued to look most likely to get the opener at Vicarage Road.
Just before the half-hour mark Chelsea found themselves down to ten men as Tiemoue Bakayoko was shown a second yellow for a foul on Richarlison.
In the 41st minute, things got worse for Chelsea. Blues' keeper Thibaut Courtois brought down Deulofeu in the box and Deeney made no mistake this time, converting calmly from the penalty spot, to give Watford a deserved lead.
Watford continued to be a constant threat for the Chelsea defence, powering forward at every opportunity.
Watford had another great chance in the 66th minute when Abdoulaye Doucoure surged through the Chelsea defence before taking his shot at goal, yet Courtois made the save.
The game opened up a bit with 20 minutes to go and the visitors put together a few attacks but struggled to carve out any clear-cut chances.
Cesc Fabregas thought he had the equaliser in the 81st minute, but the Watford keeper did well to get down low to his left and make the save, o
Watford, determined to restore their lead, continued to press the Chelsea defence and Daryl Janmaat put the home side back in front just two minutes after Chelsea thought they had earned themselves a point.
Deulofeu finally got the goal he deserved when he broke with the ball from inside his own half, ran through the Chelsea defence and slotted his shot past the Blues keeper.
Substitute Roberto Pereya rounded off a spectacular Watford performance as he made it four for the Hornets in stoppage time with a brilliant finish.
