Even though Man United previously managed to get a big win against Crystal Palace, that doesn't mean they will be able to repeat the same story in other matches. Instead of winning, they ended up losing when playing at home. A defeat that should be a lesson for Man United.
Since the match started, Man United immediately took the initiative to attack and they managed to dominate the game because of these efforts, it's just that they failed to get a goal from the several opportunities they had. Man United's performance was not too bad, but what made them fail to score was that Crystal Palace played very well defensively. Crystal Palace has a pretty solid defense and Sam Johnstone played quite impressively.
The solid defense and well-organized play shown by Crystal Palece made United look like they were unable to develop their game and failed to score a goal. Many say that this is the best comeback and the most dramatic revenge, because it happened at the Old Trafford stadium. Ten Hag made a statement, and said that this defeat was caused by The Red Devils weak defense and dull front line. Hojlund has so far not managed to score a goal in the EPL since making his debut.
I don't think Ten Hag is able to bring United out of this difficult phase, 7 matches with 9 points is a very difficult situation for fans to understand. I hope Rashford and Bruno are better off just being on the bench, when both of them don't play United can win easily.
