Would have never happened in the Delle Alpi. The fans were scarce there not because of the amount of Juve fans in Turin etc. but because it was a terrible stadium for the spectators. This stadium should have been built bigger because the appeal it has for the spectator is so much greater than the previous two stadiums. Its not a dumb at all to think that Juve, with the right stadium can have a 60,000 seated arena at near capacity for most games of the season given that the club is doing well.
Let's just wait & see how many fans we attract after the novelty of the stadium has worn off & we're again used to winning (fingers crossed).
When the Delle Alpi was new(er), attendances were high as well. Yet the last season we played there, people barely showed up while we were top of the league.
That said, public transport to & from the site has improved drastically compared to 5 years ago & the site in itself has been developped quite nicely (shopping, museum, enough parking, cleaner, etc), so the signs so far are great.
