Kimmich is gradually playing an essential role in the Bayern Munich midfield. However, his performance in recent times has also had some problems. It is unlikely that Kimmich will leave Bayern in the winter transfer, but at the end of the season, it can occur. In fact, Kimmich no longer retains the form to continue playing at the highest level as in previous years because of different injuries. Perhaps coach Thomas Tuchel has found a worthy replacement for the position.
With the class of a star who won the Bundesliga 8 times and the Champions League once, the price of owning Kimmich will certainly not be cheap. MU also faces competition from Liverpool and Barcelona.
As I have said many times, Joshua Kimminch is a man of character and leadership. He has been playing for Bayern Munich for almost 10 years now and he has been performing almost all the time. He was Germany's player of the year a few times. That proves his ability. He is only 28 years old and I believe he has a long way to go. I think Bayern Munich would loss if they don’t renew the contract.
As for his transfer to Manchester United, I would not recommend joining a team which is already suffering. They are suffering to get anything right. Another thing is you know, Ten Hag on the other hand is someone who can not manage the big players. Kimminch is a player of character and I don't think he would be getting along with Ten Hag.
