People who attended the game said that the away sector was pretty empty. Not more than a couple of hundreds.
Another thing that shouldn't be disregarded in Italy is ferragosto. Plenty of Italians are travelling abroad.
Didn't he say in the one of his reports that originally the stadium was meant to be expandable but in the end something changed and it won't be possible? Is it confirmed the stadium has the possibility of being expanded? If not, the whole discussion/whining about expanding the stadium may be very well futile.
Do you have any source for that information? An offcial press release, an interview in which Blanc says so etc.? Obviously I don't mean forum posts from some wishful thinking users or unofficial stadium characteristics copied from one forum to another that has been changed many times (originally there weren't supposed to be any rods inside the stadium, for exapmle). I know in the beginning there were plenty of talk that the stadium will have the possibility to be expanded but I think I read somewhere it won't be possible after all.
