Oh no, I no longer believe that the coach needs more adaptation. He, like Ten Hag(who had a few seasons) had a whole season, that is - enough time to just at least stabilise the team. But no, the team slid to the relegation zone. And the only conclusion I can draw is that the problem is not in the coach at all, but higher up. No coach can help them as long as there's chaos.
Yes, it's true that the conditions at every club are always different. Sometimes the problem isn't with the players or the coach, but sometimes it's with the club or something internal. As for Ten Hag, he didn't need much time to adapt, as he immediately brought Manchester United to a slight improvement at the start of the season. Ten Hag's situation actually worsened in his second and third seasons. So, in Ten Hag's case, it wasn't adaptation that was needed, but something else. However, I personally believe that the fault in Ten Hag's era lay in Ten Hag's way of maintaining harmony within the squad. I saw it as if the players were forced to compete with each other, which made it difficult to build chemistry. Because competing and trying to be the most prominent can sometimes have a negative impact on the team instead of improving it, because teamwork can fade.
I think it was his initiative and he just wanted to see players fighting for their place, as there are a lot of players at the club and it is very difficult to pick someone and put together the best squad in case of MU. They need restructuring for a long time, they keep too many players but they are cutting staff, for what purpose - it's not clear to me, they are trying to save money it would seem, but it's not bearing fruit
