Why do we continually get crowds of 50,000+ when City are drawn at home for FA Cup 3rd, 4th, and 5th round games? Because the tickets are affordable. Because tickets are affordable the demand for tickets is there.
As we've been posting for the last 10 years. Expand the stadium, make season tickets and match day tickets more affordable, and we will fill the stadium. And in doing so we will sell more drinks, food, and merchandise, which will cover the cost of lower match ticket prices.
We're now at a point where we've maxed out on hospitality inside the stadium. We've maxed out on electronic advertising boards. Maybe there's another row of electronic advertising boards to go on level 3? You can never say we've maxed out on season ticket and matchday ticket prices because they will continue to go up.(as a rule) So what's left? The Etihad Campus, the COOP Live Arena, the Collar site, and one final expansion of the Etihad Stadium.(North Stand)
