The arrogance and smothering entitlement with which they treat the rest of the Bundelisga is genuinely sickening - like you say.
They essentially view the whole of German football as a resource to be exploited to serve their success - with the National team dancing to their tune (see the Sane transfer for ample evidence), and the rest of the League apparently perfectly willing to bend over and accept their subservience in support of the Ubermensch.
All sense of fight and professional pride seems to have gone from the rest of the Bundesliga - they’re little more than an interchangeable line of witless, grinning saps willing to accept their role in the pecking order without question. It’s genuinely pathetic to see it playing out.
Their league has been completely destroyed by that morally bankrupt, preening, bore of a club - the entire German football structure is essentially one big feeder for Bayern, and the fact they accept this so eagerly makes it the most pointless, contemptible, shambolic and frankly irrelevant league in the whole of European football.
