Interesting to read that from a Bayern supporter. I don't think I have looked forward to a match with as much anxiety as I have for this face off with your team. I consider myself a quite involved fan (as in reading a lot and informing myself about useless day to day stuff, not by travelling to matches a lot) but the last six years have kind of left me numb. I wish I could just stop caring and a lot of times I think I have temporarily succeeded. The league is just frustrating and boring and that is coming from someone who is actually invested in a participating club. I really understand where the "distinctive premier league snobbishness" is coming from, at least with regards towards the Bundesliga. Why would you want to watch this league? Dortmund is usually too weak to challenge for the title and the race for the CL has teams like Leipzig, Hoffenheim, Wolfsburg and Leverkusen. Sure, they play attractive football at times but it's not like they are commanding huge interest from fans outside of Germany (not even inside of Germany for that matter).
So this season possibly did the worst possible thing to me: it did give me some hope. I never felt like Dortmund were definitely winning the league but it felt like there was a proper chance. If this hope is once again crushed by Bayern with a comparatively shit team that is just going to be maximum disillusionment. Having to watch them for a seventh time do some little celebration while complaining that the season was crap would just be really hard to stomach. It would mean that this is pretty much the most excitement we can expect in this league, almost winning it. Because I expect Bayern to be stronger again next season.
I am not even sure this is the main point. I think the club are "angry" enough as is, at least they are willing to spend. What they would probably need above all else is to get some competent people for the administration (replace people like Hoeneß, Kovac, Salihamidzic), that might be more likely if they crash and burn at the end of the season. But I think the issue is of structural nature or if you want to name it directly: financial nature. The Bundesliga is simply not generating as much money as the PL through marketing and TV deals. Add to that the fact, that the 50+1 rule that I am a staunch defender of is keeping investors out and it is not hard to understand why the league is slipping. Unfortunately I don't think a league win by a different team than Bayern will necessarily change that trend but I am afraid them winning the next six titles as well will not exactly help either.
