The rest of course there must be a very deep disappointment from their supporters due to the results of this completely unexpected match, honestly I also did not expect that until the end of the match Manchester United really could not get a goal back at all even to equalize even though it seemed very difficult. With an embarrassing result like this I hope Ten Hag has to do something to fix it, the prestige of the team is very important.
Ten Hag certainly still has room to make improvements to his team, including in defense, but he admits that everyone is frustrated due to the less than satisfactory results at the start of this season. Ten Hag must try to be better at planning his game strategy and tactics, but if players like Rashford lose confidence then of course this team will tend to fail.
Players are indeed missing, but I would not call the playing team a bad team. They had problems at the beginning of last season as well and then started a winning streak, but often had some crashes that nobody could really explain. I don't know how good Ten Hag really is. It seems that he is not a good motivator and that players sometimes have issues with them. You can then often see that players start playing against a coach instead of for the club. Burnley so far has a single point and yet Manchester United had trouble beating them, but have a look at their formation. That's not a bad formation at all.
