Spanish winger Pedro completed the rout in the final ten minutes with a cheeky chip across goal.
This game was against a side who will be challenging for a Champions League place - at least - so is not the most representative test of Huddersfield's aims.
"I think the players have done everything, left everything on the grass".
For long spells in the first half, David Wagner's side seemed to have Chelsea more or less where they wanted them. "I have to adapt myself".
However, with the recent change in management and Sarri taking over, the player made a decision to remain in west London. "I hope to be at the top of the potential of the squad in one or two months but I don't know".
The ex-banker is known for employing a rigid 4-3-3 system and has so far demonstrated his enthusiasm to bring that system to Stamford Bridge.
India vs England 2nd Test Day 3 at Lord's: Highlights
England were 131/5 when Jos Buttler departed LBW for 24 and the match very much belonged to the bowlers. The Delhi-born cricketer is presently playing the second Test of India's tour of England at Lord's.
GK Kepa Arrizabalaga, 7 - Making his debut just three days after signing for a club-record fee, there were questions about his familiarity with Sarri's style of play and the defence in front of him, but the 23-year old looked assured in goal and a confidence-boosting clean sheet came easily enough.
He said: "The game was more hard than the result. But I have seen a player who is very happy to stay here, so I think it will be no problem, the new contract".
Kepa, signed from Atheltic Bilbao for £72.1million on Thursday, had little to do for the opening 20 minutes as Chelsea hogged the ball, but made a hash of an early touch when he passed straight to Town midfielder Aaron Mooy. I saw our spirit, togetherness and good attitude today, which is what we will need to be competitive this season.
Sarri surprised many by pushing Kante out of his favoured defensive midfield role, and over to the right hand side of the three central midfielders.
And Pedro wrapped up the scoring 10 minutes from time to give Sarri his dream start in the Premier League. Players are readjusting in terms of their positions, with centre-halves restored to a back four and Kanté, a World Cup victor, now flanking a creative midfield anchor and charged with a more attacking brief.
The performance of Ross Barkley will be sure to please his new manager as well. That is not a surprise, perhaps, but it doesn't bode well for his chances of much playing time with Ruben Loftus-Cheek, Cesc Fabregas and Mateo Kovacic to come in.
