Safe standing is being trialled, Fatty. Celtic did it last season and it went down a storm. Now they're after expanding the section. Other english clubs have applied for it, and possibly even one Prem club.
It's not like the old standing, it's not just a terrace of barriers. There's seats between the bars so you can sit down if you want. And the barriers are designed so that people can freely move through them should they need to, like in the case of an emergency.
Like you say the atmosphere at most Prem games is shite. So I think now that english football fans are completely subdued, under the thumb, controlled, the state is open to allowing standing again. And the Prem want it because of falling attendances. They need to get fans back to games. And they take empty stadiums really seriously, so cheaper tickets and standing is the obvious way to go, so they're pushing it.
