Ironically, Valencia are trying to move out of the Mestalla but dont have the money to finish their (half-built) new ground.
As for Goodison, personally I think we dont have the money to redevelop it and its extremely questionable whether there is that much more money the club could make out of the matchday experience without getting more people in (given the current stature of the club, the current economic climate and the relative wealth of the surrounding area) - a better approach might be for Kenwrong et al to have a long look at the legal basis for the ban on standing areas, try and get one or two brought back, increase capacity (and funds) that way and to generally recognize Goodison's unique status as the oldest purpose-built football ground in England, one of the oldest in the world and as a long overdue antidote to all those modern, souless, money-extraction pits that everyone else has moved into.
