Bayern doesn't need to build from scratch again. They have the financial strength to replace their star players and also to compensate a fee very expensive failed transfers. Dortmund currently has two generational talents among them and even with them they couldn't really challenge Bayern post Ribery and Robben.The cycle coming to an end is actually a much bigger issue for Bayern, with Lewandowski, Neuer, Müller, Alaba and to a lesser degree Boateng, consistent performers for the better part of a decade, who are now leaving for free or retiring. Dortmund are always operating on shorter cycles and have many more moving parts. Reus and Hummels are the big concerns.
In the end football fans are opportunistic like everybody else. Of course it wouldn't work to rename the club to "RB Schalke" or anything like that but the Schalke fans were already fine with selling the soul of the club to Gazprom and especially in the current situation they'd probably see it as a way back to the top.But this is wishful thinking at best. There is so much wrong with these assumptions:
-Clubs like Schalke or Hamburg wouldn't allow someone to take them over.
-Even if they did there would be severe fan protests, the club would become plastic and lose a lot of its appeal.
-Economically it doesn't make sense to push much further than top four for profit seeking owners.
-You kill 50+1 and no one knows how many more micro plastics will spawn and pollute the system. It's already too many.
I mean, you use the term plastic a lot, what does it actually mean for you? Because the clubs in question are already extremely commercialized anyway.
