Again, couldn't agree more - but the impression I got was that they are looking to time this bankroll gamble very carefully, and that is very hard to do. Even if they managed to time the downfall of Bayern to the correct year, there's no saying that a Dortmund or even an HSV or someone couldn't storm to the top of the league. I think what they were getting at is, Leverkusen aren't going to just sink into the mid-table but rather try to build something and bide their time.
It'll be funny as fuck if they fail, though.
