Charlie Taylor rued a missed opportunity as the Clarets conceded a last-minute goal to lose to 10-man Leicester.
The Foxes had England defender Harry Maguire sent off after just four minutes for bringing down winger Johann Berg Gudmundsson.
But Burnley couldn’t take advantage and even though Dwight McNeil cancelled out James Maddison’s opener before half-time, Sean Dyche’s men were consigned to a fourth successive defeat when Wes Morgan nodded home.
And with just seven games to go, the Clarets remain just one place above the relegation zone – two points clear of Cardiff City in 18th place.
“It was a hugely frustrating game and afternoon for us,” admitted Taylor.
“The three points were there for us and we’ve come away with none, so it was hugely disappointing not to even take a draw in the circumstances.
“In the first half we weren’t good enough, in the second we created a few chances and had a few appeals and things just haven’t fallen for us.
“It’s hard, especially when you get two banks of four in front of you. It’s hard to break down.
“And then to conceded like we did at the end is hugely disappointing.
“I think that’s what’s made it more frustrating, the manner how we’ve lost.
“It’s hugely disappointing and a missed opportunity, I think, with how it went.”
Taylor was a central figure in two key moments as he teed up McNeil for a classy finish from the teenager, who claimed Burnley’s 100th Premier League goal at Turf Moor.
And Taylor – a driving force for the Clarets from his position at left-back – was then denied a penalty in the second half when referee Michael Oliver didn’t see enough in a challenge from Wilfred Ndidi as the defender burst into the box.
“I thought as though I got across and in front of him and he touched my heels.
“I thought there was contact, the referee saw it differently,” said Taylor.
Burnley now head into an international break with the chance to re-group ahead of another home fixture against Wolves.
Cardiff then visit Turf Moor a fortnight later for what could be a pivotal fixture and Taylor says now is the time to focus minds.
“We’ve got seven massive games. We want to be a Premier League team next year and to do that it’s in our hands and we’ve got seven games to make sure we do that,” he said.
“We need to get everyone behind us and get the wins we need to stay in the league.”
