Until Serie A teams build new stadiums and find other lucrative revenue streams, we will always lag behind EPL and La Liga in attracting the big name talents.
The way I see it as of now, is Serie A is a "stepping stone" league. We're able to find and purchase young up and coming talents, and then inevitably sell them on to the rich douchebag clubs (Man Shitty, Barca, Real, Man United).
Big changes need to happen in order for Italian football to get back to its glory days.
