From memory there were two links. I clicked on buy and it said I wasn't eligible. I then clicked on the one below (code I think) and it worked. It was also a bit confusing how you entered a second code.Well that was absolutely pointless. I was eligible to register, but not eligible to buy.
I’ve bought 16 match tickets, three of which were VIP, three shirts, three gold memberships, and an assortment of tatt from the club shop, and they still block me from 60% of matches including the UECL final.
This kind of nonsense makes me want to stop coming to any games.
