Bayern Munich is about to lose a player in this team. Joshua Kimmich is a player who is under contract with Bayern Munich but this player is linked to Barcelona to join this team in the next days.
On the other hand, Manchester United is seeking a midfielder and Manchester United can be another possible destination for this player.
It seems Bayer Munich should increase the offer to keep Joshua Kimmich or they will lose their player.

This is indeed a great news and it's more than a random speculation now. Bayern Munich recently are now linked with a move to sign Portuguese player Joao Palhinha a player who currently plays for Fulham in midfied. I see that wanting a player like him means they'll be letting a player leave. I'm not surprised Joshua Kimmich would be that man. He's really won a lot for that great club, I feel like it's time fir him to explore and fave other challenge's....
For Barcelona, they really haven't found that perfect replacement for Sergio Busquet since he left the club, they have struggled in midfied also because they lacked a player who will shield the defenders. Too many goals have been conceded due to the absence of a concrete Defensive Midfielder.
The move to Barcelona would be great. And I also feel like, Bayern Munich needs the repair in midfied.
I feel like Barcelona is just looking for Sergio Busquet as you said and they are doing it with closed eyes because they want to fill his pacle the team while all the players they hired so far for this team, couldn't have good enough performance to take the place of Busquets in Barcelona.
Joshua Kimmich is another midfielder they target while Bayern Munich is going to play smarter and if you are right about Joao Palhinha they already found an alternative player as a midfielder for their team.
