Frank de Boer's short reign at Crystal Palace was plunged into further turmoil after an early blunder from Lee Chung-Yong brought their fourth straight Premier League defeat.
Burnley new boy Chris Wood pounced on Lee's dreadful backpass to put his side in front with less than three minutes gone, and the hosts held out to leave De Boer's job hanging by a thread after a 1-0 loss.
Palace perhaps deserved something from a hugely-improved performance and should have got it when Scott Dann headed wide from point-blank range in injury time, but that may not be enough to save De Boer.
