What is clear for sure is that Manchester United management still trusts Ten Hag and with this large financial support it is hoped that Ten Hag will be successful according to their expectations.
Only thing is, we see how Manchester United develops next season, whether he will succeed with all his efforts so far or not.
Yes, and this is the source of concern

Indeed, whatever is taken from Manchester United's current decision has its own risks where when they are looking for a new coach, re-adaptation and reshuffle will occur again. But on the other hand, keeping Ten Hag with the existing situation and some of the minus notes he showed was also actually a big risk that Manchester United had to bear later.
Actually in this case it doesn't matter too much if in the end Ten Hag stays in the squad but with a few notes like he can't intervene directly on player transfers because some of the transfers he expected were actually more of a failure than really profitable. In addition, his arrogance must also be minimized because in the end with what he has shown in these 2 seasons we can see that his ego and authoritarian attitude in coaching Manchester United is very visible so he needs to hold back more if he really wants to get full trust from the players.
