Newcastle United secured a much-needed win at Selhurst Park to pile the pressure on Crystal Palace manager Pierre Sage.
After a drab first half low in quality, Newcastle raced into a 2-0 lead by scoring twice in 11 minutes after half-time to secure a third top-flight win under Matthias Jaissle.
William Osula's first-time finish from Jacob Murphy's 47th-minute cross set the Magpies on their way before Harvey Barnes finished well to double the lead and spark a chorus of boos from frustrated home fans.
Lukas Hornicek saved well to keep out Adam Wharton and substitute Dario Osorio.
But Palace, who had been the better team in the first half, crumbled after Osula marked his first start since the opening weekend of the season with his first goal since May.
The Denmark forward took his goal really well as Newcastle won at Selhurst Park for the first time in six years when Steve Bruce was in charge.
Palace had made a lively start but with Jean-Philippe Mateta and Daichi Kamada both having attempts, but the problems are mounting for Sage.
The Frenchman is only four months into a three-year contract but has now presided over five defeats in eight Premier League games.
