Thanks Sing, do you think increasing the capacity behind the goals would improve the atmosphere. I would prefer to add seats there first rather than in the corners. Corners would be great to create the wrap around. Not sure why clubs don't at least fill the corners with panels of some sort. They could then be used as very big and visual advertising or player images etc.?
Increasing the capacity without filling it would have a detrimental effect on the atmosphere I think. I like your idea for covering the corners for more advetising space.
