I've never been bothered by the capacity, especially when factoring in potential for safe standing increase.
For a bit of perspective, if Everton have a full house in the last game at Goodison, and gave everyone in attendance a ticket for the 1st game, they could do so without selling a single ticket in the new South stand.
Further, if the new legislation moves from 1:1 to only 1:3, it will only take 5.5k converted safe standing spaces to go over 60k, which is similar to the bottom tier of the new South Stand, with further provisions for the north stand lower as well.
There are some minor things about the stadium that i would love to be slightly different, mostly design features that were probably not done for good reasons, including cost. But it looks amazing as it is, and more so each passing week.
It's going to be incredible and something to be proud of.
Good illustration there about how much bigger the new place is. Hadn't thought of it that way.
