I agree with you it is too expensive and I feel for the thousands who have been priced out. (I suspect you're in the same boat as me and it is affordable for you.)
But the stadium is full for every league game and nowadays for even early rounds of the domestic Cup competitions. So I don't see why, or how, the club could reduce prices significantly.
Hypothetically, an 80,000 stadium with prices at say two-thirds current values, would be a model that could work.
That's crazy thinking I know but then, who could have predicted the last 21 years when we first moved into the COMS in August 2023?
