Erkka, Juve are an Italian club and not a Turin club. So I don't think we'd be plastic if we moved. Agreed, it hasn't been done before and might look a bit weird in the beginning, but if that's going to bring more fans to our stadium I don't see why we shouldn't do it.
But to be fair I don't know where in Italy we have most fans. If we do have lots of fans in Turin there's obviously some other problem. If we have more fans up south it would be actually more fair to move there.
I do disagree with the Delle Alpi being a horrible stadium. I actually like the architecture and it is far from cold on the inside. It's no English stadium, I admit, but it definitely isn't as bad as some here picture it. Remember we had about 50 000 regular visitors back in 1998 and that was the same stadium. The Allianz Arena might have worked wonders for Bayern, but they'll only keep those attendances up by bringing good football and giving football a cleaner image.
That's perhaps the biggest problem with Italian stadia: they look intimidating towards families. Like I said before, we should go through the same transition as the EPL. Football needs to become clean and friendly again. Because I would go to a Roma-Lazio derby when given the chance, but I doubt everyone would.
