You sacrifice "atmosphere" for revenue. Honestly, that is where this new money has to come from. They must make it so that a family of four can come to the game, regardless of alliegance, and enjoy a match. The Ultras are always going to be there no matter what. Therefore, that is not the "new money" that Juve will have to be looking at.
The Ultras can be as boisterous and loud as they want to be, but once they cross that line, then no self repecting person is going to risk taking their children to watch a match.
Point Blank. If Juve wnat the Delle Alpi filled consistently, the Ultras are going to need to behave themselves.
