I can't disagree about the Italian fanbase part, but it is rather insulting to the aforementioned trio that Marchisio be placed on the same pedestal.
As for being a sure starter for Juventus and the NT, that isn't a point I can argue with either, as facts are facts. However, at Juventus, and unlike the national team, we do have options, and the significant amount of money generated from any potential sale of Marchisio (hypothetical scenario of course) could also allow us to strengthen other areas, as well as the midfield. Mind you, I am not in favor of selling him, but if an indecent proposal were made, it would be hard to refuse.
