I still don't understand one thing. Why did Nagelsmann wanted to manage a national team already now? I mean he is a really young manager after all. He was climbing the steps really quick in his career as the last club he managed was Bayern Munich as you know. 
After that I really expected him to continue managing big clubs like that.
I think national team jobs are a better fit for managers with big careers at a little old age minimum too. Because you are like a little active than being retired while managing a national team.
You are rarely playing games.
A little information, recently the national team led by Julian Nagelsmann had to lose in the last 8 of Euro 2024 after Germany lost dramatically to Spain in the second round of extra time. Germany had to swallow the bitter result because it had to let the euro be held in its own country.

You are rarely playing games.Yes, after parting ways with Bayern Munich, he decided to lead the German national team. Maybe he wants to be more relaxed by handling the national team like that. Perhaps he should have been annoyed when Bayern Munich suddenly decided to sack him at the end of the season.
Nagelsmann is a young coach who has good abilities, in his previous team he always provided something good for his team. Although in the end he had to accept the risk as a coach who had to be suddenly fired. As a young coach he has a very long time to continue improving his abilities, he must develop even more.
