There is no delay, just people getting antsy needlessly, It's 3 weeks away.
Liverpool have details out but go look at their breakdown of selling tickets, it's unnecessarily complicated involving previous rounds attended and ballots and if you look at the dates they've set aside, they've got long gaps between each different set of criteria. Citys method is far more streamlined and easier, they don't need to be rushing out information as quickly. I'd take citys system over that scouse mess every time.
I also noticed the cheeky twats at Liverpool are charging nearly £8 per booking to have tickets delivered to anybody in the UK and even more for overseas fans with sales strictly online only. I'm hoping that's the wonderful FSG skimming their fanbase rather than the FA, don't want to see any of that shit from city.
