There's a good point made on that forum Percy linked to - for its size, Villa Park doesn't hold as many as it should. It's badly configured and you should be able to do a lot more both in terms of capacity and facilities.
Villa Park’s issue has always been it is constrained by Trinity Road and Witton Lane like a pair of tweezers. Until that’s addressed expansion is very difficult. And I love my view there but the Witton Lane Stand really isn’t fit for purpose.
