Despite these challenges, Borussia Dortmund remain confident that Kimmich can help the team improve its performances. They believe that he has the potential to become a top-class player at the highest level, and they are hoping that he will be able to contribute to the team's success in the coming seasons.

In conclusion, Borussia Dortmund's decision to extend Kimmich's contract shows their commitment to him as a key player. While there may still be some challenges ahead, the club remains optimistic that he can continue to perform at a high level and contribute to the team's success in the future.
