I heard if you’re a “foreign” fan, you have a good shot of writing the ticket office & getting tickets because you’re more likely to spend a lot of money at the official store. Don’t know if that’s true as I haven’t had a chance to try it myself.

I’ve also heard that Anfield doesn’t always sell out, so you’d think that would mean tickets should still be on general sale, but…I don’t know why they make it so difficult to buy tickets if the stadium isn’t always at max capacity.
