Because Ten Hag had a very difficult season at Man United, it was felt that he was considered a bad coach. And especially as Xabi's replacement, it would certainly be considered very bad if he couldn't deliver the best results.
Unfortunately, in this opening match, Ten Hag was actually embarrassed by being defeated by Flamengo U20, even though it was a friendly match.
The coach Eric Ten Hag is most under discussion due to his failure in Manchester United and his replacement with the coach Xabi Alonso in Bayern leverkusen. But the main thing is predicting his performance by seeing the pre season matches is completely unfair. Maybe they planned some changes for the season and noticed mistakes in pre-season matches. I think it's wrong to make an image about someone by seeing his previous mistakes. It's not necessarily the same things that will be repeated in another place or with new faces. So, let's motivate him somehow so that he can do well and even more well. He just needs to focus on his goal and avoid the negative things circulating about him. And his relation with the players must be as strong and friendly as possible.
It's too early to start judging ten hang because of his preseasons games which are just for the purpose of practice and keeping fit we have to wait until the new season starts before we can start throwing stones at him and again we should not expect ten hang to replicate what Xabi Alonso was able to do in Leverkusen because anyone expecting ten hang to do so well be disappointed as Xabi was super exceptional while at Leverkusen
