"Well, Matthaus is too silly, with his series of increasingly young wives," says a Dortmund friend. And, of course, Hoeness was imprisoned for tax fraud.
The message is clear: Football in Germany is something good and noble. And this social responsibility is all borne out on the ground floor, where there is an on-site course for indoor football, rooms for football education and space for parties and school and corporate events.
So far, the museum has drawn visitors from all over the world, including the Dutch just over the border, Chinese and Japanese.
"Maybe because we have Kagawa," says a staff, referring to Shinji Kagawa, the most famous of the dozen Japanese players in the Bundesliga.
After almost three hours in the museum, I emerge into darkened streets beckoning with the alluring smell of sausages and kebabs. Even though it is winter, Dortmunders are nursing beer outside pubs and restaurants. Billboards advertise rock concerts and cultural events.
The following morning, I walk around Phoenix See, an artificial lake created out of the grounds of former steelworks. Expensivelooking houses and apartments overlook green meadows edged by restaurants and cafes. Some footballers are said to live here.
Like the phoenix, Dortmund seems to have risen from its ashes, with football as its fuel.
