While de jong will be a DM.
Gavi- pedri
Casado - De Jong.
Replace de Jong with kimmich, who is a better player and a better DM even though neither are the best in the world at it.
But Kimmich doesn't play that role in Bayern, and Flick didn't use him there.
That was Grotzke, Kimmich simply sucked at it.
I would prefer to either bring a natural CDM or continue to have faith in Casado & Bernal. Ideally it us the later but it will depend on how we see Bernal recovery process, if we have a plan C for the position (Gavi? Prim? Soma?)
Kimmich is a rich man Sergi Roberto, he is far better player obviously, but just like Roberto, whenever he has a run in one position, fans will scream he is wasted there because his natural position is something else.
Great to have if he is one of ours, but I won't pay premium money for him.
Also, I would take Mingueza back as RB or just use Casado there when Kounde is rested, assuming that Flick isn't convinced with Fort.
If there is a free agent I would take from Bayern, it is Sane, because he is far better player than Torres, even if he is frustrating himself.
