A Christian Pulisic hat-trick helped Chelsea hammer Burnley 4-2 at Turf Moor and extend their winning run to seven matches.
Without a Premier League goal entering the match, the £58million forward coolly slotted home mid-way through the opening half, before doubling the Blues’ lead just before half time.
The American completed his hat-trick with a fine header before Brazilian star Willian compounded the misery for Sean Dyche’s side.
Jay Rodriguez did, though, register a stunning late consolation before Dwight McNeil saw his strike deflected in as the hosts started to make Chelsea sweat.
The eventual win helped Frank Lampard’s men claim victory in their fourth consecutive away league match, having scored at least three in each of those matches to consolidate on a strong start to the season.
Willian displayed Chelsea’s early intent, driving a left-footed effort over the bar in the fifth minute. As the half wore on, though, the grit of Dyche’s Burnley started to show as the Clarets started to build momentum.
But in a flash, they were behind. USA star Pulisic - signed from Borussia Dortmund last January and touted as a potential replacement for Eden Hazard - showed his quality as he pounced on Matthew Lowton’s error.
The forward accelerated beyond the backtracking James Tarkowski before sliding a left-footed effort inside the far post to score his first Premier League goal.
Burnley looked for an immediate response, with Ashley Barnes heading wide after being picked out by Tarkowski, but it was Chelsea who looked the more dangerous.
The 21-year-old had a close-range effort deflected, forcing Nick Pope into a fine reaction save, before former Brentford star Tarkowski had to deny the American with a desperate block.
Tammy Abraham might have done better when he bent his 39th-minute strike wide of the far post when turning into space on the edge of the box, but Lampard’s wait for a second goal did not last much longer.
Clearly invigorated by his opening goal, Pulisic picked up the ball inside the Burnley half, drove into the box and fired a right-footed strike which flew inside the near post, via a Ben Mee deflection, to double Chelsea’s lead on the stroke of half time.
The visitors, though, had Kepa Arrizabalaga to thank after Kurt Zouma’s attempt to cut out a near-post cross shortly after the break ricocheted off the Spaniard and away from goal.
It was Pulisic’s night though, and no-one was denying the Pennsylvania-born forward. On 55 minutes, he claimed his third.
After a corner kick was cleared out to Mason Mount, the former Derby man whipped in a cross which was directed into the far corner with a fine header.
Less than two minutes later, Willian got in on the action. Abraham picked out Willian, who beat Erik Pieters with a step-over and slammed the ball into the bottom corner.
The hosts were almost destined to score in the 62nd minute when Rodriguez broke through on goal, but Fikayo Tomori’s sensational last-gasp tackle denied the former England international.
Callum Hudson-Odoi, a second-half substitute, tested Pope before being booked for a dive inside the box - VAR overruling the original decision by Michael Oliver to award a penalty.
The academy product then flashed a ball across the six-yard box, as home fans booed the England international for his dive, but none of his team-mates could convert.
Burnley, though, were not done and Rodriguez struck late with a wonderful effort to claim a not-undeserved goal. His 86th-minute strike from 30 yards had sufficient whip and dip to beat Kepa and score his second of the season.
A late flurry then saw McNeil then scored a wicked deflection of his own from the edge of the box - off Tomori - to wrong-foot Kepa.
But in the end, it was too little too late as the Blues claimed another three points to finish the evening in fourth place.
