I queued for over 24hrs in 1992 for one of the 300 / 400 tickets we got in that season's away derby. It was a fucking shambles then, it's a shambles now. In those days I never, ever missed a game, home or away. But I knew that, as a "regular" season card holder, I was pretty much guaranteed a ticket (provided I sat underneath the Main stand roof all night). I, as well as a few other blues (Electric Blue's Noel amongst them) made the MEN the following day - we were incensed at our treatment. Plus ca change.
It's not the size of allocation for me - I hear what you say re Celtic, but I think most Prem games would be a straightforward 10/15% allocation, it's the absolute lack of transparency. You say supporters' clubs got 200 tickets. Why isn't that confirmed by the club with an actual breakdown of who got what? If I'm sat on 18.5k points and I see Linfield/Cheadle/Yorkshire have been given XY and Z tickets and that any of their members can get one, not people on 18.5k points, I've a right to be well and truly pissed off.
Tunnel club / Joe's / Corporate - yes, they get 1st dibs, but let's know how many. And in what order..tunnel 1st etc. An exact breakdown. It won't happen, it'll be considered commercially sensitive. But it smacks of City pissing on their mancunian chips.
