I really don't see us filling 55,000 tbh, thats a big uptake on the 39,000 that go now, back in the 80,'s heyday, we were only getting about 29,000 on average, and that's when football was affordable....................I think you're being over cautious. Everton is on a roll ,the city of Liverpool is on a roll. We would fill 55,000 for most games. Imagine casual supporters being able to buy a seat where you could actually see the pitch !
Everton's prices have been frozen for a while and has loads of cheap tickets for young fans. A season ticket costs less than £30 per game . Whether you call that affordable depends on your own circumstances of course.
