The rivalry between Ajax and Feyenoord football clubs, who hail from Amsterdam and
Rotterdam respectively, is one of the fiercest in the continent. During the 1980s there has been a large number of significant hooligan incidents between the two clubs and amongst other Dutch clubs. Another major hooligan incident not related to the derby in 1989 was the
Staafincident, when an Ajax hooligan threw a metal rod at the goalkeeper during a match against
Austria Wien. ==Incident==
