The result maintained Sarri’s impressive start to life in west London since moving from Napoli to succeed fellow Italian Antonio Conte in July.
The 59-year-old is now unbeaten in his first 11 Premier League games as Chelsea head coach – equalling the record set by Nottingham Forest boss Frank Clark between August and October 1994.

Forest would go on and finish third that season, which remains the highest finish by a newly-promoted side in Premier League history.
Sarri has yet to taste defeat in any competition, bar a 2-0 loss to Manchester City in the Community Shield at Wembley in August.
Sarri can move ahead of Clark if he can avoid defeat against Everton in their next Premier League match at Stamford Bridge on Sunday.
It is also the first time in 30 years that three teams in England's top division have remained unbeaten after 11 rounds of fixtures.

Last season's runaway champions Manchester City thumped Southampton 6-1 at the Etihad Stadium on Sunday to move two points clear at the top of table.
The result meant Pep Guardiola’s side took full advantage of Liverpool’s 1-1 draw with Arsenal at the Etihad Stadium on Saturday, with the Reds dropping to third behind Chelsea following their win over the Eagles.
Chelsea will now turn their attentions to the Europa League and a trip to Belarus to play BATE Borisov on Thursday.
Sarri’s side hold a six-point lead in Group L after winning all three of their matches so far and can secure their place in the knock-out stages with a fourth victory on Thursday.
