Why do you only look at the Manchester United team in the last 2 matches between these two teams, in fact we have a different possibility as to why Manchester United could lose even though in the match a few days earlier against Crystal Palace they could also win, I think it's because the Crystal Palace team play with different strengths.
Ten Hag cannot be completely blamed because the Manchester United team's situation is very bad right now, Ten Hag doesn't have many choices because many Man United players are injured.
They got different results though their opponents were the same team. Those matches have just occurred, so I think it portrays their current performance and it is the easiest assessment material that Ten Hag can use to carry out evaluations. Losing is the responsibility of the entire team but so as not to repeat the same mistakes and lose again, the coach must make a change and have the courage to get rid of players who are hampering the rhythm of the game.
It seems that Crystal Palace learned from yesterday defeat and tried to improve their strategy to be able to break down Manchester United defense and I noticed that the formation used by Crystal Palace previously was different when they were beaten by Manchester United in the League Cup, the formation currently used is the same as that used by Manchester United, namely 4-2-3-1 whereas previously 4-2-2 might have been a big influence for Crystal Palace when using this formation.
Manchester United found it difficult to equalize even though they dominated the ball game and the 19 shots that Manchester United took were not on target so the Red Devils had to accept defeat and Crystal Palace was able to take full points thanks to Crystal Palace victory is now in 9th position just above Manchester United with earned 11 points.
