I hope I am wrong, but do think differently. Allegri has experience of winning Scudetto several times, Inzaghi hasn't even once. That might make the difference.
Our coach is clearly still learning how to win and managing gas at the same time, as rotation in a long season is a must. But more often than not, over-rotating. He tried to get a just-enough strong XI (in his opinion) over Sociedad (x2) and Benfica, failed with goal difference. He tried again vs Bologna, failed in extra minutes. Always a hair-width gap between us losing and winning in decisive matches.
On the other hand, Allegri is doing that the entire season and always succeeds. His team never get tired.
Naive and fox I am seeing. Plus the CL torture is making things in the league worse.
He had experience winning when the league was a one horse race, when Inter and Milan were lead by complete incompetent owners spiced with financial hangover so it was a complete free lunch. Without Milan and Inter the Scudetto is cheap for sale.
No other coaches in serie a history had an easier run in winning the scudetto than him. And while he is good at getting a consistent performance in serie a it is still within that context.
Inzaghi is only 47 years and had never coached a clear favourite or dominant team the way allegri has. You make sound like Inzaghi is same age as Allegri he isn’t so it’s not surprising he hasn’t won a Scudetto yet. Many first do this from their mid forties to start fifties. Yes we seen some in their early forties but in most cases those were not restrained financially the same way Inzaghi team has been, Inzaghi likely had won a scudetto at this point if not for that reality.
