Yeah, there is Bayern and Borussia then, so chances is low for them in nothing will change in upcoming years. I don't follow Bundesliga that much, I knew that Eastern clubs don't have big achievements, but I didn't thought that there is so few clubs from East playing Bundesliga and Bundesliga 2.
isn't that expected, East was under-developed, and there is hardly money there to have bigger clubs (I would argue that everything is about money in football these days)
Even Hertha is West Berlin, which has been playing Bundesliga when it was founded.
Leipzig is only playing Bundesliga because of RedBull.
A funny story: it's called RB Leipzig, which Leipzig Fans says it's "RasenBallsport Leipzig " (GrassBallsport Leipzig) but of course, it's totally not because of RedBull.
