Tuchel was sacked by Bayern after a disastrous season in the Bundesliga, but with Negelsmann it was different, his results with Bayern were not disastrous. And Bayern invited Negelsman to return to the post of head coach, but he refused because at that moment he was the head coach of Germany, in fact, he now remains the coach of Germany, but it is not known what will happen after the loss of the Spanish national team, perhaps he will also be fired because a loss at the quarter-final stage at the home Euro may be perceived too negatively.
Nagelsman made the right choice by declining an offer from Bayern Munich to return as the team's head coach after they fired him for no reason. I've been wondering why Bayern Munich fired him in the last two seasons without offense. However, despite disgracing him in front of the fans and sacking him, they still want him to return to the club, which seems to be an insult if he does. Bayern Munich's management believed Tuchel was the greatest and fired Nagelsman, so I don't see why he should accept the position. To be honest, Nagelsman did his best in Germany match against Spain, but the players seemed exhausted in the last minutes of the game, so I don't think the German national team will fire him just because they were eliminated from the Euro tournament.
The pressure just appears to be almost much already and the season is yet to start, they are even yet Start pre season. And everyone is almost fired up about their expectations from Bayern Munich. In as much as kompanys past record is vital in trying to judge and gauge possible expectations from him, we should also understand the chances of the odds been defiled and he becomes one of the best Munich has had after a long time, this is mostly possible. At this point everyone is just speculating and making a guess or better put a prediction as regards that which kompany will be able to achieve with Bayern Munich.
I agree with you, Kompany may prove people wrong to become successful at Bayern Munich next season since many people doubt him because of his poor performance at his previous team. Bayern Munich is a big club, and no manager wants to miss out on such an opportunity, Bayern Munich did not consider Kompany previous team performance, but the club believes he has the strength to improve the team next season. The season is yet to start, and some people have started to put pressure on Kompany that he will not be successful in his first season. We are being hurried, we need to wait 3 to 4 weeks of the season to see if he can bring success to the club.
