Are you serious? This whole thread is about a rise of issue with hooligans in the Netherlands and there has been multiple issues of local fans clashing with police in the last years - googling Netherlands hooligans police clash is already good enough, so I spare myself linking this stuff. And tbh I believe it's a bigger issue in the Netherlands than in Poland right now.
Yes, but a different kind of clashes. Fans rushing the riot police before the match has even started is a very different thing - although Feyenoord fans like that sort of thing abroad sometimes.
How often do you really see players arrested? All I was saying that hooligan stuff and arrests happen, it's part of the game even if we try to eradicate it. To go after players and club staff feels like a low blow and nothing but a cowardice (which in all honesty I generally expect from policemen all around the world)
Again, the police arresting players here appears the be a separate story, about player behaviour inside the stadium after the match.
You can't just generalize this way. It doesn't explain anything.
Edit: To be clear, I absolutely do think the Netherlands have a hooliganism problem. I have posted on that in this thread as well, on how I think it's tied in with a wider issue in Dutch society. But I think none of that explains why Legia fans rushed the riot place before the match yesterday, or why Dutch police decided two arrest two Legia players after the match.
