Angelli shouldn't be even leading a nail saloon with how badly Juve was mismanaged. For a long time they were an example of how to run a football club. Excellent transfer policy, fantastic squad, long-term manager in Allegri consistently bringing trophies and challenging in Europe every year, making 2 CL finals.
But instead of staying patient and sticking to long-term strategy that was clearly working , they started playing musical chairs with managers, gave biggest 5-year contract in history to a 33-year old with shot knees, and basically ruined a decade of meticolous planning within 12 months of madness.
