Pirlo would likely been dropped even if he was still in Italy, his level dropped and relatives I have in US says he isnt even impressing in MLS.
Giovinco actively chose the big paycheck over the limelight of competetive footie, I would still call him and wanted him there because he is good (literally one of my top few fav players still), but I understand Conte or the FIGC drawing the line somewhere. You basically get yourself out of contention leaving the main stage when you join lower start up level league so its not much to dispute on footballing terms in itself.
