Our biggest win at Turf Moor ever came courtesy of goals from Alvaro Morata, Ross Barkley, Willian and Ruben Loftus-Cheek.
It was another dominant away performance from Maurizio Sarri’s men and four goals certainly didn’t flatter us - we also hit the woodwork twice and Joe Hart was the home side's outstanding performer. Eden Hazard's absence through injury made it all the more impressive.
Morata opened the scoring midway through the first half with a confident finish, and two goals in five minutes either side of the hour, well-struck long-range efforts from Barkley and Willian respectively, made the outcome comfortable.
Loftus-Cheek continued his own rich vein of scoring form with a goal in stoppage time to add gloss to the final scoreline. The margin of victory is our greatest in this part of Lancashire, beating our 3-1 success here in 2014. It also extends our unbeaten start to life under Sarri, and moves us up to second in the table ahead of Tottenham and Man City’s game tomorrow night.
The back problem Hazard picked up in last weekend’s draw with Manchester United ruled him out, so Pedro started his 100th Chelsea game alongside Morata and Willian.
The only other change from our most recent Premier League encounter was the inclusion of Barkley over Mateo Kovacic in midfield. Thursday’s hat-trick hero Loftus-Cheek was named on the bench. It wouldn’t be long before he was on the pitch again and back among the goals.
For Burnley, Robbie Brady started his first game of the season.
On a chilly but beautiful Lancastrian afternoon, it was actually the hosts who started the sprightlier. Our struggle to get a foothold in the game was evidenced by the fact we didn’t complete a pass in the opposition half until the seventh minute.
Still, Burnley didn’t register an attempt of note in that time, and it was the yellow-shirted Blues who first threatened with 10 minutes on the clock.
An N’Golo Kante cross from the right was cushioned by Willian back to Barkley, outside the box. His bouncing shot was heading wide before Morata diverted it goalwards with his head. Joe Hart leapt to his left to claw the ball out. It was a fine save.
Brady then fired an effort wide after Kepa had not claimed a cross with Sam Vokes’s arm for company.
The next attack was Chelsea’s and ended with Willian shooting straight at Hart after Azpilicueta’s clever cross reached him at the far post.
The chances kept coming. Vokes stabbed wide from a tight angle, and Willian hit the inside of the post after opening his body up latching on an intelligent Morata pass.
The Spaniard then forced a Burnley mistake in midfield with the help of Kante. Jorginho seized on the loose ball which was quickly worked to Kante and on to Barkley. He weighted his through-pass to perfection and Morata did not hesitate in toe-poking it past Hart. 1-0 to Chelsea midway through the half.
In response James Tarkowski headed over from a corner, and then the continually-dangerous Willian saw an effort deflected not far wide.
On the half-hour, Pedro left the field in some pain holding his stomach. Loftus-Cheek was his replacement in the front three.
Morata had two opportunities to double his and our tally before the interval. Marcos Alonso created the first with a driving run and pass, and the striker’s first touch inside Ben Mee was a very good one. This time his toe-poked effort flashed wide of the left-hand post.
Then, from a typically searching Jorginho ball over the top, Morata controlled well and fired goalwards, only to be denied by another super stop from Hart.
After scuffling in the six-yard box in time, Tarkowski and Morata were booked, as was Willian for simulation. It had been an eventful end to a good half of football.
It was Morata who had the first good opening of the second period after Willian had scurried down the left and delivered. He couldn’t quite get over his header from close range, but we wouldn’t have to wait long to double our advantage.
It was a goal made and finished by our midfield. Jorginho dropped a shoulder, taking two Burnley players out of the equation as he did, and shifted it on to Kante who quickly found Barkley. Our in-form no.8 needed no second invitation to try his luck, and from outside the box he arrowed a left-footed drive into the bottom corner with aplomb. In doing so he became the first English player to score in three consecutive league games for us since Frank Lampard managed it in 2013. The away end certainly enjoyed that one!
That was on 57 minutes and five minutes later Willian made it three. Again the strike was from range, again there was little pressure from Burnley, and again it couldn’t have been better placed, whipped from right to left.
Olivier Giroud, not long on for Morata, curled wide after more good Willian work with 10 to play, while Cesc Fabregas was introduced for his first league outing of an injury-affected campaign.
Loftus-Cheek hit the side-netting in the closing stages as the game meandered to its conclusion with plenty more Chelsea possession and olés from the delighted travelling support. As we entered stoppage time Giroud was incredibly denied by Hart, who touched his point-blank header on to the underside of the bar.
But there was to be time for one more Chelsea goal, as Loftus-Cheek added to his midweek treble with a close-range finish that deflected over Hart after we kept the ball alive from a corner. It was a fine end to a handsome away win.
