That's your opinion and of course, it counts to you, but I'm not sure you focus on what most see as relevant.
Most Juventus fans will be more concerned about their 35+ league titles and numerous other accolades, rather than that Sunderland have more seats in their ground, and most Sunderland fans would give up their higher attendance average this season, to have had the equivalent success. You're comparing a bus with a formula one car.
I am not. The original article referred to Sunderland getting higher crowds than Juventus (though the main point was that the Championship is getting higher crowds than Serie A.) As is often the case the thread has digressed from that.
