As Italian I am extremely pissed off with the current situation but every big team had its bad periods in history, there is not a single team that has been getting results for 50-60 years in a row, it's simply not possible, things change, just like there are golden generations there also are bad generations, it's like a wheel. National teams, clubs, it doesn't matter, it's like that for everyone.
I think something, that European countries including Italy are rapidly needing a Young population, that they should give more opportunities to people from other countries to be able to settle , only those immigrants who do contribute to a country and that they are given facilities to have a Family and make a life there, I think that would help a lot, but Italy's problem is escalating very quickly to worse.
