The thrashing left the champions only a point ahead of fifth-placed Tottenham Hotspur and drew greater focus on to Conte's position as head coach, with the Italian admitting post-match that his team are playing with fear and it would "be very hard to turn the situation positive". Despite bringing in Olivier Giroud and Ross Barkley in January, Conte has failed to get the side together and perform but reckons he is not losing sleep over saving his job.
It is the first time since 1995 that we have lost two consecutive Premier League games by a margin of three or more goals. Meanwhile, the agent of Chelsea legend Gianfranco Zola, Fulvio Marrucco, said: "Sarri as coach would be Abramovich's dream", per Neil McLeman of the Daily Mirror.
"I think we all know this kind of players it happens everywhere in the world, this type of striker sees the goalkeeper coming for the ball, I make myself as small as possible with my belly on the ground and he manufactures the contact".
Ill-discipline has been a problem for Chelsea this season, with Bakayoko the latest to have seen red in a campaign of far too many cards. Before that he laid the blame exclusively on the club's board for transfers and the public criticism of transfer strategy caused tension. He called for support from the club administration and requested the board to come out in open and put their trust on him.
The former Barcelona coach is on a year's sabbatical after winning nine trophies in three seasons at the club. "But I'm not anxious".
The situation quickly disintegrated as Costa refused to train with the reserves, leaving Chelsea struggling to find a buyer.
Despite this, he could be relieved of his duties in the next few days after two consecutive demoralising defeats to Bournemouth and Watford which have left them fourth in the table with Spurs breathing down their neck, just one point behind.
He is particularly keen on trying his hand in the Premier League and would relish the challenge of going up against old teammate Pep Guardiola, as well as Jose Mourinho.
And instead of signalling a Chelsea comeback, the equaliser turned out to be the prelude to a Watford onslaught that produced three goals in less than 10 minutes.
