Peterborough manager Darren Ferguson was left fuming at Turf Moor after a dreadful defensive showing saw his side ship five goals at Burnley.
After leading for 15 minutes of the first half Peterborough imploded, with Charlie Austin scoring twice in the second half as Burnley ran riot to win 5-2.
"Pure and simple, we're conceding too many goals," said Ferguson. "I either persevere or replace them (the defence). I can replace them from within. Unfortunately they're not listening to me. It's really unlike me to criticise my players in public. Normally what I say to them in the dressing room is kept in there."
He went on: "We simply aren't defending well enough. I've tried different combinations to get it right but it's not been working. We've looked at the loan market. I'll talk to the chairman. And I've got other bodies in the building that can start.
"It's six defeats in a row. It's embarrassing now and we have to do something about it. It's the same old cliches, rolling our sleeves up and so on."
Chris McCann headed Burnley in front in the seventh minute but it was all square soon after as Lee Tomlin converted from the penalty spot for Peterborough after a challenge by Jason Shackell on Nathaniel Mendez-Laing.
Three minutes later Peterborough were in front as Mendez-Laing pounced on Tomlin's pass to score, while the same player almost added a third soon after for Posh. But after going in front Peterborough waved the white flag, with Michael Bostwick turning Austin's low shot into his own goal after the striker was put through by McCann.
Austin will want to claim the goal as his own after adding two in the second half. He slammed Burnley back in front on 74 minutes after poor defending from Peterborough and then completed his hat-trick from the penalty spot.
Junior Stanislas slammed home a fifth goal late on and manager Eddie Howe was delighted with his side's recovery as they battled back to put Peterborough to the sword.
"It was a crazy game. It was so open for both teams," said Howe. "There could have been a lot more goals than there were. We've got things to work on defensively but attacking-wise we were excellent and it was pleasing."
