Similar to Juventus few years ago and our struggle to get back on the top. Clubs of that magnitude can't stay in the shadows for too long. They face difficult times in every decade; blame it on generation change, poor investments and decisions, or whatever, but eventually they have the infrastructure that enables them to bounce back. Huge number of fans, big income, appeal, etc...Milan was even worse in the end of 90es; they literally sucked for two years in a row ('97 and '98), finishing in the middle of the table, with bunch of old players, but year after they won title.
