Amsterdam, the Netherlands
Teams: Ajax | Oranje
Excelsior has had the luck of getting some decent Feyenoorders and Fries on loan in their good years, RKC the same now (and they have had decent squads in the past as well with the likes of Greene, Boulahrouz, Decheiver, Bosz, van Hintum, etc.) Volendam is the real jojo. Sometimes too good for the first division, but not good enough for the Eredivisie the season after.
Cambuur has indeed been away for a long time now. The last time they were in they still midget De Ron in goal.
Sparta got screwed the last time by De Mos, because otherwise I think they still would have been in. Had some decent players of course.
