Is the Bayern midfield currently the best in Europe? I don't see many that could be better.
City is solid with KDB and Gündogan, Real had the best midfield with Casemiro, Kroos and Modric. But those two are getting old, especially Modric.
Liverpool is solid, PSG is quite meh imo.
Kimmich and Goretzka still has the age ahead of them, plus with the addition of Sabitzer it looks even stronger. Not to forget Roca could still turn out to be a good signing, although I doubt he will play a bigger role when fighting for a spot against those mentioned.
