Stoke City would have themselves to blame not to have responded equalized as they had many glorious chances which would have resulted to goals for them.
Nigerian wingback, Victor Moses, who had a good game, provided the assist for one of Morata's goals.
Morata then added another two for the Premier League champions, completing his first hat-trick for the club to make it a 4-0 drubbing.
Stoke enjoyed a good spell towards the end of the half with Mame Biram Diouf's overhead kick dropping over the bar and Fletcher had an effort blocked on 43 minutes. I repeat, it's not simple to win away against them.
After his hat-trick against Stoke this afternoon, Morata has now scored six goals in his opening six games under Antonio Conte, a record that has proved the doubters wrong. He did not get it, with Morata rounding off the win in the final quarter-hour.
Iran nuclear deal can not be renegotiated: Hassan Rouhani
We have very, very limited contact with their representative here at the United Nations from time to time. The deal also ensures that United Nations inspectors have regular access to known nuclear sites in Iran .
"I am pleased for Alvaro's performance, pleased for the performance of the team".
Alvaro Morata's goal was his first of the season to NOT be scored via his head - the other three were all headers. Costa is likely to be watching his replacement from the stands at the Wanda Metropolitano. A deft chip by Fabregas on the edge of the Stoke penalty area saw Azpilicueta chest the ball down to in-running Morata who tapped the ball into the empty net - game well and truly over.
Chelsea sit now third in the table, just three points behind Manchester City and Manchester United.
Stoke boss Mark Hughes has now failed to see his side win in their last five matches, and three consecutive defeats across multiple campaigns will undoubtedly damage their morale.
"I think on this issue, we want to thank him for what he did with this club and we wish him all the best for the future, ' Conte said when quizzed on the topic of Costa's departure in his pre-match press conference on Friday".
If Stoke wish to push on, or even avoid a relegation fight, they must fill their squad with more players are able to perform consistently.
