Nothing, absolutely nothing. Supporters of Juve and Milan don't seem to care that their clubs went invincible in the past 30 years. They are just holding on to this. Which they can if they want to.When you haven't won a Premier League title in 16 years and are the only one of the classic "big 4" not to have won a Champions League (or even made it to the final in 15 years), what else do you have to hold onto besides the invincibles season?
