When we heard about Tuchel leaving Bayern Munich some people were happy to see these events because Tuchel didn't have good relationships with some players in Bayern Munich and especially with Joshua Kimmich. Joshua Kimmich is not a bad player but he doesn't have a good relationship with Tuchel and since Tuchel is going to stay in Bayern Munich, Joshua Kimmich prefers to leave the team.
It seems nothing is clear about the next season for Tuchel and Bayern Munich so if he stays there, Joshua Kimmich will leave.
Some teams like Arsenal and Liverpool are also linked to this player and they are ready to send offers for Joshua Kimmich.
However, there were some other offers from PSG and Chelsea for this 29-year-old player but he rejected these offers.

Isn't it certain that Thomas Tuchel will leave Bayern Munich? and if I'm not mistaken it has been confirmed by both parties, both Tuchel and Bayern Munich and it is a mutual agreement that Tuchel will not be at Bayern starting next season, so Joshua Kimmich will remain at Bayern Munich unless he really wants to leave the club to gain experience others with elite clubs in different leagues.
Bayern Munich has not yet appointed a replacement for Tuchel and it is rumored that Jurgen Klopp will be the coach there but that has been denied and the latest news is that perhaps the ones who will be the coach at Bayern which has never been rumored in the media, so the names currently linked with Bayern Munich could be will not be the coach at the club and the name that will be announced will be a surprise for many people, they just have to be careful enough otherwise their appearance will be at stake
