Burnley boss Sean Dyche admitted his side failed to sustain the "clinical" edge that had drawn eight points from their previous four games as they lost 2-0 at QPR on Saturday.
The Clarets failed to make their chances pay as Leroy Fer and Charlie Austin scored at Loftus Road to consign Dyche's men a defeat which leaves them 19th in the Premier League table.
Dyche was left to rue a superb stop from QPR goalkeeper Rob Green to deny George Boyd a first-half goal, and says his side must become more ruthless in order to stay up.
"There's a tinge of disappointment, but it's still a tough game against a very experienced side," said Dyche. "Rob Green made one absolute worldy save and another very good save from Scotty Arfield.
"We need to be more clinical, we knew that and we have started to be that, but we just weren't today.
"I think they know they had a game today, but you take wins how they come and I certainly would."
The loss sees Burnley two points from safety, while QPR have climbed out of the relegation zone for the first time since September.
