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.
I think the possibility of Tuchel leaving is higher than Kimmich leaving. Kimmich is one of the players who most strongly opposes Tuchel. Over the years, Kimmich has been considered an irreplaceable pillar at Bayern, but since Tuchel arrived, he has repeatedly spoken out that Kimmich is not suitable for the position of holding midfielder, and this clearly doesn't make Kimmich satisfied, and the climax was the time Kimmich could not keep calm and got into a fight with a member of the Bayern Munich coaching staff. It's clear that the relationship between Kimmich and Tuchel cannot be repaired and one of them must leave to help Bayern stabilize.
But it seems that Tuchel is not only displeased with Kimmich and also many other players at Bayern like Thomas Muller. Besides, there is a group of players defending Tuchel, including Neuer, Musiala and Kean, who are all important players of Bayern. Therefore, if Tuchel stays, Bayern's internal affairs will continue to be unstable for a long time with conflicts between the two groups of players and with the coach himself. Therefore, Tuchel's departure is probably the most optimal solution, and the announcement that Tuchel and Bayern will terminate the contract on June 30, 2025 is the answer for all.
