Dirk Gentlypapereyes Isn't that much the same with English clubs in Europe? You can only, really, get tickets through the official ticket office and that comes with travel included.
God knows how the ticket office in Reading would cope if we ever actually got to Europe.
These days it's mostly subcontracted out to specialist operators, so I think the club would be Ok as long as they';d setup one of these deals first - and you could be sure the second the club qualified for anything in Europe the operators would be hammering on the door looking for business, so I reckon they'd do OK.
Not sure I like the implied compulsion that you can only travel on "official" transport, though. People have to be able to make their own travel arrangements and just buy tickets.
I read a big piece on it about 2 years ago in 4-4-2 which stated that and something more recently in the Guardian that strongly implied it.
If its changed, then its changed.
