This is the Sportverein 1919 Mainz-Gonsenheim, with the Vertical Village in its delicate pastel tones looking benevolently down from on high.
They currently play in the Southwest Regional League which is pretty much the lowest level of organised football (soccer) around here. Village/small town stuff.
But they've got their own website (which is at least as good as Mainz 05's) and their merchandise is dead cheap
And Jürgen Klopp lives just around the corner, so maybe they can get some tips from him...
