Problem is that he is out of his depth. Juve have grown faster than the management were ready for, and in many ways they tried to recreate a situation that plays more to their strengths rather than a situation that fits the natural evolution of the club and team as things stand. They tried to repeat the formula of the Conte season, where they brought in some written off players, some on a free. That's not the formula a team knocking on the doors of CL success could do with. Marrotta singlehandedly set the team back a couple of seasons with his approach on the market and it's crazy he was given a free run to do so. You simply cannot spent 100m on the mercato and not replace the one prime asset you were so quick to sell. It's shameful. Almost incompetent.
I just read an interview he gave where he acknowledged that we lost some of the experience with ate ex, Pirlo and the like, and it's so sad, but it was his job to replace what he identifies as a missing element in the team. You can rebuild a team all you want, but you've got to do it from the team's point of evolution not a process from scratch. We are largely thanks to Marrotta, today a team with little or no identity because it's clear as day Allegri doesn't know what the fuck to do with the collection of randoms that Marrotta has handed him. If Allegri actually wanted Hernanes as AM, he would be playing him there more than he has. He's been screwed over as far as this season goes. The saddest outcome in all of this is that we are most likely going to be missing out on CL football next season, and have only ourselves to blame.
The cherry on the cake being that Pogba will be sold st a cut price to compensate for the lack of CL money when we fail to qualify, and Morata will probably want to return to the biggest club in the world away from a mediocre club that struggles to recreate a formula with a coach that is good at tactics not building teams. Forget the percentages. And forget the past. This team cannot go any further with this pragmatic style of management.
