Yikes!
So is it a generally reliable rule of thumb that if a club is wealthy, glamorous, have name recognition in other countries, and have sophisticated and aggressive PR departments, that there's something sketchy about them?
I wouldn't be surprised. In many things non-sports, power and money simultaneously corrupt people and attract minions.
Take a look at Chelsea's owner, for example. They're basically his tool for laundering his dirty oil money.
Also, Liverpool have been involved in so many incidents over the years (Heysel (Google it, they don't take responsibility for it), supporting Suarez's racism, etc) that if you've got kids, probably best to avoid them.
I'm not too fussed about slating any other club.
