Blaming individuals makes no sense.
It's just that we're not good enough for this competition. Or at least for higher stages.
You can't be shocked either because we keep selling our best players while we don't even replace them properly. Not only we butchered our midfield but later on we butchered our defense as well (but I'm still glad we sold Bonucci).
And it won't change much. We'll just keep our policy. Selling for big money if big offers arrive & investing it in young talents, keeping tabs on young Italians, and searching top talents that won't go to top clubs.
