Watford piled the pressure on Antonio Conte as a late flurry of goals secured a thumping 4-1 win over 10-man Chelsea on Monday Night Football.

On a miserable night for the Premier League champions, the out-of-sorts Tiemoue Bakayoko was sent off after half an hour before Troy Deeney scored the opener from the penalty spot in the 42nd minute.

Chelsea, who were beaten 3-0 at home by Bournemouth in their last game, looked as though they might snatch a point when Eden Hazard scored a brilliant equaliser in the 82nd minute.

Man of the match: Gerard Deulofeu

But Watford scored three times in seven minutes through Daryl Janmaat, Gerard Deulofeu and Roberto Pereyra to secure victory for new head coach Javi Gracia on his home debut.

While it was a perfect result for Gracia, it is likely to raise even more questions about Conte's future and how much longer he will remain in charge of Chelsea.

The visitors were under pressure from the start, with Abdoulaye Doucoure dragging a shot wide, Deulofeu shooting into the side-netting and Deeney missing a glorious chance from a corner when he sliced off target.

Willian spurned a good opening at the other end when he fired over from close range, but Chelsea otherwise rarely threatened.

They also lost possession too often, with the main culprit being Bakayoko, who was shown two yellow cards in five minutes and dismissed on the half-hour mark after catching Richarlison.

The first half got worse for Chelsea when Courtois came sliding out and caught Deulofeu in the box. Deeney stepped up and dispatched the penalty with the goalkeeper staying in the middle of the goal.

Watford went close to extending their lead in the second half as Deulofeu and Richarlison both shot narrowly wide.

Chelsea did improve after the introduction of Olivier Giroud and it looked like they might grab a point when Hazard fired in a fantastic shot from 25 yards.

But parity did not last long as Watford responded in stunning fashion.

Janmaat made it 2-1 in the 85th minute when he played a one-two, danced away from a couple of tackles and finished into the bottom corner. Deulofeu then fired in from Doucoure's through ball before Pereyra fired home in injury-time to round off a thumping win.

Opta stats

Chelsea have now lost more league games this season (6) than they did in the entire 2016-17 campaign (5).

The Blues have lost consecutive Premier League games by a 3+ goal margin for the first time since October 1995 (1-4 vs Man Utd, 0-3 vs Blackburn).

All three of Troy Deeney's Premier League goals this season have been penalties against 'big six' sides (Arsenal, Manchester United and Chelsea).

Three players have now received red cards for fouls on Richarlison this season (Davinson Sanchez, Jonathan Hogg and Tiemoue Bakayoko), more than any other player in the division.

Chelsea have been shown seven red cards in all competitions this season, two more than any other Premier League side (Watford 5).

Man of the match - Gerard Deulofeu

Deulofeu was influential for Watford on his home debut. He won the penalty from which Deeney gave the hosts the lead and had as many shots (4) and key passes (4) as any other Watford player.

He capped an excellent performance by getting on the scoresheet late on.

What's next?

Chelsea are on Monday Night Football again next week when they host West Brom while Watford travel to West Ham on Saturday.
