Manchester United suffered a second successive defeat at home in the Premier League as Joachim Andersen's superb strike gave Crystal Palace an impressive victory at Old Trafford.
The two teams were meeting for the second time in five days, with Erik ten Hag's side comfortably winning 3-0 in the Carabao Cup on Tuesday.
But Palace rested a number of first-team players for that game and were a different proposition on Saturday as they produced the perfect away performance.
After Tyrick Mitchell cleared Rasmus Hojlund's effort off the line, Palace took the lead when Andersen superbly drove a first-time effort into the top corner after a free-kick.
