Watford 4-1 Chelsea: 5 Talking Points
It was a frustrating evening to forget for Antonio Conte and his Chelsea side, who were outplayed and embarrassed by their London rivals at Vicarage Road.
Troy Deeney broke the deadlock from the penalty spot after Gerard Deulofeu was hauled down by an onrushing Thibaut Courtois, before goals from Daryl Janmaat, substitute Roberto Pereyra and Deulofeu himself helped seal a comfortable victory following Eden Hazard's curling effort to equalise with time running out.
Tiemoue Bakayoko's first-half dismissal made matters even worse for a Chelsea side who lost consecutive Premier League matches by a three-goal margin for the first time since October 1995.
On that note, here are 5 things we learned from a big win for the Hornets:
#5 Home debut to remember for Deulofeu
Gerard Deulofeu has been one to criticise himself, as he knows a player of his ability needs to perform well on a consistent basis. In three separate seasons for Everton on loan spells, he has displayed his world-class capability but only in brief flashes.
For someone with something to prove, it was certainly a standout performance from the Spaniard. At 23, he's at the stage in his career where he really needs to kick on and settle into the player that he can become - but has been left frustrated by irrational decision-making in the final third.
He scored one, created the penalty and could have had a hat-trick, in truth! But for some poor finishing on his part, as well as lacking composure in the rush of the moment.
A constant threat going forward, his blistering pace and tricky dribbling style always prove menacing for defenders to contend with - it was the same case on this occasion against a Chelsea backline who have struggled recently to keep clean sheets.
The Spaniard won the Man of the Match award for an electric display, it's definitely the platform he'll be looking to utilise going forward in future from now until the end of the season. Who knows, maybe Javi Gracia's post-match comments are right and he could earn a surprise inclusion as part of Spain's World Cup squad. Has to remain consistent, though.
