Highlights:

Hoffenheim are the fastest risers thanks to the club gathering a following from their surrounding region.

11 of 18 clubs get 40k or more fans on average. Compare this with England, where 6 clubs (Manchester United, Arsenal, Newcastle, Sunderland, Liverpool, Chelsea - have I missed anyone?) can accommodate that many fans.
