So what do you guys think will take for Serie A to be a top 2 league again? It seems Calciopoli has really hurt the league on a long run, but Juventus seem to be on top again despite having been relegated due to Calciopoli. Perhaps building a new stadium helped them out? Also, doesn't Roma also want to build a new stadium?
it will take that the chinese owners of Inter and Milan "consolidate", making the Serie A a league where 3/4 teams (Juventus, Inter, Milan and Roma or Napoli) can fight every year for the #1 spot. It will take ~4/5 years, as soon as Inter and Milan get a spot in CL and start skyrocketing their revenue.
Juventus is owned by a very competitive and business oriented family. They "know" how to run the business (also in teh less legal ways ) and it didn't take them long to reorganize the company to start winning again, taking advantage of their huge fan base (more income). The stadium is a minor aspect in this.
Roma is building a new stadium indeed, but their bigger limit is the modest fan base, which heavily limits their revenue.
