To their credit, City's old owners gave Maine Road to the council (being as they were getting a new ground for free).
But there's nearly 500 homes on that site now, the money that generates isn't chickenfeed. Even more so now than in 2004.
Having lived in Moss Side pre-2004 I can tell you it wasn't that desirable
But as I say, the other fly in the ointment with the ground is that if you buy Wolves now, you have to build a new stand soon, which won't come cheap and won't necessarily generate money back very quickly.
