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
It's certainly reasonable to hold back on Ten Hag's expectations in his first season with Leverkusen, especially since the team isn't particularly equipped with top players. I don't think we should expect too much next season unless Leverkusen can pull off more unexpected surprises. I also won't judge Ten Hag negatively for those preseason games, as the true assessment will have to be seen in the more serious matches that will come next season. That will be more appropriate to conclude after Ten Hag's first season with Leverkusen.
So, what can we expect from Eric Ten Hag? He hopes he can return to the pinnacle of his coaching career and achieve the same success he achieved during his time with Ajax Amsterdam. This isn't just his first season coaching Leverkusen, but it's also his first coaching a Bundesliga club. He does have considerable coaching experience, but he lacks the experience to coach a Bundesliga club. And if, with ETH, Bayer Leverkusen can't maintain its status as a title contender, then hiring ETH as Leverkusen's new coach would be a poor decision by the club's owners. It's still too early to judge ETH, but the signs of Leverkusen's decline under ETH are already evident.
Ten Hag coached Manchester United and when coaching Manchester United he lifted a trophy with them even though he didn't coach them well as Manchester United was down in the English premier league, we all know that English premier league is one of the most difficult league in the world, for me I will even say is the most difficult league in the world right now, so he may do well in this Germany League, one thing I have learnt when it comes to football is never to say a thing can't happen, Ten hag may surprise everyone next season.
Bayern Leverkusen has great players and all Ten Hag will do is to use this players very well and everything will go well, I believe he has an assistant coach there in Bayern Leverkusen and the assistant coach has been in the club for some time now so the coach will put Ten Hag through in some things.
No body believed PSG will win inter Milan and lift the champions League trophy and no body believed Chelsea will win PSG and lift the FIFA club world cup, so no one should judge Ten Hag now untill next season starts.
