i was in that crush as well squirty flower piss poor organisation 4 turnstiles and a large area packed with city trying to get in down into 8 lanes then 4 lanes chaos, took nearly 45 mins to get in and missed 1st 10 minutes.
as for trouble in town , i walked all over never saw any problems certainly no blues with feyenord flags or singing feyenord songs only heard about the old sailor but was told it was nothing major,
for me a good trip except for the match, but i learned a long time ago never let city spoil a good piss-up !
