your observation is correct. Man United didn't have a game that looked like a team. There is no figure at Man United who is the driving force for other players to play well. they only play individually to show off their own skills.
when Man United players can really realize that, and change their playing patterns to be able to play better as a team. maybe they can end the season better. If not, perhaps there is nothing to expect from the Ten Hag squad this season.
The collectiveness and level of creativity of the players is still quite weak, where every time they play they tend to show individual qualities which end up being quite ridiculous. If Erik Ten Hak doesn't try to evaluate his players then I think it will be quite difficult for them to finish in the top five this season. Last season we saw the sharpness of Marcus Rashford as a player who was quite productive in assisting attacks and scoring goals, but this season Manchester United lost that figure.
Now they have Garnaco whose performance has improved a lot but because he is selfish in playing inconsistently, he will have the potential to follow Marcus Rashford if he continues to play like this. Failing to advance to the last 16 in the Champions League and European League made the coach's condition even more depressed because he had to accept much worse consequences.
