well, not really…
schalke opend theirs in 2001, parkstadion was fkin outdated, this was planned before gemany even got the world cup. Hertha obviously rent the stadium, Glubb does so as well. Hannover rent their stadium for less then a million a year, it was actually somewhat of a scandal, when it became public. HSV paid only about 15m for renovations prior to the world cup.
Lautern just fucked that one up all by themselves…
This is not the reason though. Leverkusen is s smallish city, right next to Colone and they allways had a limited draw and were a “smaller club”, that never had any major success and whose biggest accomplishment it was to win a match here and there against 1.FC Köln.
When Leverkusen rached the 1st division, in the 80s, FC && Gladbach were two of the biggest clubs in the country and scraped up the fans of the region, pretty much all the Leverkusen fans I know are from the city. From what I know and thats not really, really deep Leverkusen upped their investment, after they survived the fist few years in the league, Bayer invested 2 million deutsche Mark into new players, wich was a lot back then and established themselves as one of the better/top third teams in the league. Fans of other teams then slowly grew to dislike the club, that only had an attendence of around 10k, in a time, where most of the cash clubs made came from selling tickets, being bankrolled by a company, it then became a lot worse, when they were contending in the late 90s, early 2000s.
