We are fighting hard as a team for Antonio Conte - Cesar Azpilicueta

Cesar Azpilicueta insists he and his Chelsea teammates are not letting down under-fire manager Antonio Conte.

Chelsea lost 4-1 at Watford on Monday night as pressure on Conte's position intensified.

Eden Hazard looked to have rescued a point for the visitors, who had Tiemoue Bakayoko sent off in the first half, after Troy Deeney had put Watford ahead from the penalty spot.

But Watford scored three goals in the last six minutes to wrap up a comprehensive victory and leave Conte's future in the balance.

Some bookmakers have suspended betting on the Italian being sacked as Chelsea sit 19 points adrift of the Premier League leaders Manchester City and one point clear of Tottenham Hotspur in fifth.

The defeat at Vicarage Road coupled with the 3-0 loss against Bournemouth at Stamford Bridge last week indicates there is an issue with the form of the reigning champions.

But Azpilicueta, after the game, declared that the players were still fighting for their manager.

Asked if he felt like the players were letting Conte down, he said: "No. I think if you see the training sessions, we all fight hard.

"We are the first to be disappointed with the way the last two games went. That's really hard. We are getting penalised in the bad moments we are having during the game.

"It's not a long period, but in this league, which is so tough, you get punished as soon as you drop a bit. We are here altogether. We are all disappointed with the result.

"I know that there has been speculation all the time in the five to six years I have been here. As a player, what I want is to come back to the training pitch as soon as possible, work hard and get into Monday's game, to get the three points and our confidence back."

By the time Chelsea kick off at home to West Bromwich Albion on Monday, they could be outside the top four -- something Azpilicueta admits would be a bitter pill to swallow.

"It will be difficult if that happens because we were in a very good position -- we were fighting for the second place," he added.

"But after two defeats we have dropped. The gap [to the teams behind] is getting closer and closer.

"We have to know that on Monday we might start out of the top four but we have it in our hands to get back into it."

After Hazard's equaliser, it appeared as though Chelsea could even leave Watford with all three points -- only for the hosts to respond in scintillating fashion.

Daryl Janmaat scored to restore their lead before Gerard Deulofeu and Roberto Pereyra sealed the win as new coach Javi Gracia oversaw a victory in his first game at Vicarage Road.

"It is a massive win,'' Janmaat said, according to the club's official website. "We needed three points and we did it, we played a great game.

"We knew they were a bit under pressure so we wanted to get on them from the start of the game.

"I think we did well, we pressed them really well. We still had the belief we could win because we had a lot of energy, more than them, and that was the key."
