If it was after the match.
I was as close to that as you can be without getting involved, we walked through the cordon then through churchyard and climbed the barrier on our way to the crown, mixing with them almost immediately, cops never stopped us crossing the road, straight away the blades inside the pub were goading the pigs as they walked past, then plenty of verbals between everybody walking escalated, knowing what was gonna happen we walked up towards the aldi and everything went off behind us, was some decent punches thrown as well not your hokey kokey style gesturing, both sides got stuck in, I'd describe it as traditional..
Cops we're about 2 foot away and got into them, some of those taking part will have got back home on monday morning and the "lucky" ones will get a knock shortly.
Btw : The Crown was open straight after the match, I left there at about half four ish' and went to fannies, didn't see any more bother after the panenka..
