Sorry mate but this simply isn't true. I've already posted on here in the last day or two that plenty of games in the 18-19 season went to general sale or at least very low seasoncard points.
I can keep on writing these posts but I guess people don't pay any attention - United, Liverpool, possibly Chelsea, Arsenal and Everton plus games with small allocations like Bournemouth in the past are difficult for people to get tickets for, no doubt about it. But there's usually about 7-10 games per season where most seasoncard holders should be able to get a ticket for. In fact there's some games where if it wasn't for Cityzen matchcard holders we wouldn't sell out at all.
