Regarding Halstenberg: i first heard rumors that he might join Hannover 96 a few weeks ago and now it seems to happen. Halstenberg is a current player for the german national team, with a transfer to a club of the second Bundesliga i think he is risking his spot in the national team for the upcoming EURO 2024 which is played in Germany.
As i readed from a few different news pages the transfer from Halstenberg to Hannover 96 is already done and fix.
I dont think that about he is join Hannover into the second league will be have an affect for the National Team.
If he keeps up the performance and playing good i guess he will be playing the EURO 2024 with Germany.
Halstenberg played for Leipzig last season and if in this transfer window Halstenberg leaves to Hannover, then at least it might be a drop level. But who knows whether Halstenberg will get a place in the German national team later, because playing in the 2. Bundesliga does not seem to be a definite guarantee for Halstenberg to get a place in the German national team. Yes indeed, maybe with Halstenberg playing at Hannover it will make Halstenberg get more minutes to play, but i'm not sure Halstenberg get an increase performance also because Halstenberg will play in a team is at a lower level than the teams playing in the Bundesliga.
