and Ajax; Cruyff wanted a contract extension, but Ajax balked on account of his age. This transfer angered both fanbases; Ajax fans were outraged that Cruyff had jumped to their biggest rival, while Feyenoord fans did not like the fact that an Ajax legend would be joining their club. Some Feyenoord fans protested his arrival by hanging banners saying "Feyenoord Forever, Cruijff Never" being one of the more civilised ones. Many fans would also whistle and jeer at the newcomer during the friendly pre season games and whenever his name was announced in the stadium.

In April 2005, riots took place around Feyenoord's ground involving hooligans from both sides and the riot police. Travelling Ajax fans had demolished the train transporting them to Rotterdam, and were forced to wait outside the stadium until the match was over. Meanwhile, Feyenoord supporters who had just seen their team lose 2:3, were determined to clash with rivals from Amsterdam, who had not seen the match.
