Rouven Hennings made his long awaited debut as the Clarets fell to a frustrating defeat at Ipswich.
The German striker was a 60th minute substitute at Portman Road, after gaining international clearance to finally start his career in England.
But it was to be a disappointing night as, after a dominant first half that saw Michael Kightly strike the inside of the post, two goals in five second half minutes from Freddie Sears and David McGoldrick inflicted Burnley’s first league defeat of the season.
Sam Vokes started his first game of the season, replacing Lukas Jutkiewicz in attack in the only change to the weekend draw with Birmingham.
And the visitors made the brighter start, coming within inches of taking the lead inside the opening five minutes.
Kightly’s cross fell to Jelle Vossen, whose mis-kick fell kindly for the wide man to strike a shot off the inside of the post and back into the grateful arms of Bartosz Bialkowski.
Town’s response was a few wild efforts from lively winger Ainsley Maitland-Niles and last season’s top scorer Daryl Murphy.
George Boyd also failed to find the target as the half hour approached, as a free kick fell to him on the edge of the box.
But it was fine work from Boyd that set up a big chance for Vossen as the clock ran down for half time.
The wide man’s flick found Kightly, and his low ball cut across the edge of the box fell nicely for the Belgian, whose first time side-foot was comfortably parried away by Bialkowski.
And as Burnley ended the half on top, David Jones was only just off target with a wicked, curling free kick from the corner of the box.
By the hour mark, there had been no more moments of concern for either defence. And at that point, Sean Dyche introduced Hennings for his debut; the German replacing Vossen.
But within 10 minutes, the game had gone away from Hennings and his team mates.
The hosts for once carved Burnley open in the 65th minute - and when Maitland-Niles crossed low into the box, a delightful near post flick from Sears found the bottom far corner.
And five minutes later, Town put daylight between themselves and the Clarets when McGoldrick met Niles’ right wing corner with a firm downward header that crept in at the far post.
Michael Keane came close to setting up a grandstand finish with a bullet header at the far post that Bialkowski was equal to.
And there would be no way back for Burnley, who were forced to make the long trip back north pointless on a frustrating night in Suffolk.
