Two goals either side of half time from Leicester City’s record £30m Islam Slimani helped condemned the Clarets to a second straight 0-3 away defeat.
Manager Sean Dyche would later reflect on “four minutes of madness” as the Algerian headed home a Christian Fuchs free kick and a Riyad Mahrez cross to leave the Clarets with a mountain to climb.
And the final nail in the coffin came late on when the exceptional Ben Mee unfortunately turned a Mahrez cross past Tom Heaton to complete the scoring.
Ben Mee puts through his own goal
It might have been a different story if the Clarets, with their own record signing Jeff Hendrick making a full Burnley and Premier League debut, had gone in level at half time following a confident first half display.
But once the Champions got their noses in front, it always looked a difficult task for Sean Dyche’s men – and so it proved!
Republic of Ireland midfielder Hendrick took his role in a five-man midfield, alongside Dean Marney and a slightly advanced Steven Defour.
That meant Sam Vokes reverted to the bench, leaving Andre Gray as the lone targetman.
And Gray was inches away from getting on the end of an early George Boyd cross from the left as Burnley settled well.
At the other end, Daniel Amartey flashed a shot high and wide from a half-cleared corner.
From Burnley’s first corner, on the quarter-hour mark, Michael Keane headed just wide, but the whistle had already blown for a foul by the centre back.
Hendrick soon controlled Mee’s drilled pass and let fly as the Leicester defence backed off, but his shot failed to test Ron-Robert Zieler in the Foxes goal.
The 25th minute brought Leicester’s first real opening, as dangerman Mahrez picked the ball up on the half way line and sprinted clear, rounding Mee only to be denied by Heaton’s legs as he went for the near post.
The Clarets best chance of the half arrived 10 minutes before the break, following a sweet move down Leicester’s right.
Boyd eventually picked out Scott Arfield at the far post and the Canadian international found Defour with a header back across goal.
The Belgian, however, had to generate all the power on his own header and Zieler stooped to collect in the centre of goal.
City then went straight down the other end and from Fuchs’ excellent left wing delivery, Mahrez somehow headed wide at the near post.
But finally, after a slow-burner of a half, the deadlock was broken from another Fuchs’ delivery in the first of two added-on minutes.
The Austrian this time fired over a free kick from the left that Slimani headed firmly past Heaton from six yards.
Three minutes into the second half, Burnley had a mountain to climb when Slimani doubled the advantage. Mahrez was the provider with a cross that deflected kindly into the path of the Algerian, who again nodded past Heaton.
The Clarets made two substitutions either side of the hour mark, as first Johann Berg Gudmundsson replaced Arfield, then Vokes was introduced for Defour.
But it was Leicester who pressed for a third, as Mahrez’s drive from just outside the box was just too high and then Fuchs’ saw his shot slide wide off Boyd’s boot.
And the goal finally arrived when Mee, stretching to cut out Mahrez’s cross from the by-line, unfortunately turned the ball past Heaton at the near post.
There was almost a consolation for the Clarets when Gudmundsson’s wicked free kick from distance hit the wall, but Zieler changed direction to parry away the effort.
And the Clarets’ last chance to salvage something went when Vokes headed Stephen Ward’s left wing delivery wide of the far post.
