This, i wonder why not many people realized how good Ten Hag is. Despite his club that performed badly in EPL, he was achieving what Arteta did just only in two season. It's not something that could be achieved by other coach.
Newcastle and Palace took multiple decades just to win a trophy. Meanwhile, ETH gave two in two seasons. i totally agree with you United have no coaching problem when ETH was there, but things changed when he gone, and Amorim took the chart. They officially have coaching problem.

Amorim has the worst statistic compared to other coach, including the worst season for Ten Hag.

His succeeds in Braga and Sporting Lisbon are still not able to change Manchester United, instead they make Manchester United getting worse. The Glazer aren't that wrong because they sign Amorim when his statistic is pretty well.
I think, they should sack Amorim.

It seems that Man United should start considering recruiting a coach who is already experienced in the English Premier League. They should stop experimenting by bringing in coaches who have never handled a club in the English Premier League before. ETH was brought in from the Eredivisie for a reason, because at that time ATH was at the peak of his coaching career with various trophies that he presented to Ajax Amsterdam, but in fact when he went to England he was still unable to achieve what he had hoped for, and so it is when talking about Ruben Amorin, we know how the young coach brought Sporting CP to win the title again, but that is something we did not see when he moved to Man United. Indeed, Amorin has only been at Old Trafford for half a season, but during that time Amorin has not succeeded in growing the fans' trust in him.
