That doesn’t answer my question.
KDB is probably the best attacking midfielder on the planet right now I think they’d swap him in a heart beat personally.
Sometimes it's not just about the individual but the chemistry with the team mates and leadership qualities. Lewandowski for example is always MUCH better if Müller plays behind him because Müller's runs draw defenders away, that's something De Bruyne wouldn't do. Müller is also a leader in the team and especially without crowds you can hear him constantly giving commands on the pitch, he is basically a second coach for Bayern at this point.
There is also a reason why other AMs like Götze, James and Coutinho all "failed" at Bayern, in the end it is always Müller who wins out.
That doesn't mean De Bruyne isn't an exceptional player but you would be forced to play him behind Lewandowski/Müller and that is just an insanely attacking formation because we already play with a high line, ball playing CBs, have no "pure" DM, CMs who like to attack/move into the box (Kimmich/Goretzka) and also very attacking wingers (Gnabry/Comand and soon Sane) as well as FBs who push forward too, especially Davies.
It is probably one of the main reasons why we didn't go all-in for Havertz because he'd face a similar problem and why we didn't want to pay the fee for De Bruyne BEFORE he moved to City (we were interested in him).
On top of that De Bruyne would be too expensive now to force a move for a 29 year old player. We'd not get enough years out of him for the price City would be asking.
