I would beware the opinions expressed in this thread because most are assumptions. Liverpool has always been a game where Scousers would get everywhere. I remember this from Maine Rd, and in my block there wasn't 1 incident of a Liverpool fan celebrating in our block. And that's in 600 people.
What is true though is that in midweek Cup games, a lot of seasoncard holders are no-showing and they are being replaced by another group. A lot of assumptions are being made about this group. IMO, they are locals. Others call them tourists but they can't evidence this.
