If you think this squad is where it should be, in 3rd place, in Serie A, that that position is its ceiling, that is where I fundamentally disagree with you.
We've had the supposedly wonderful window under new management and we are worse than we were last year, points-wise in the league, CL position-wise, and injury-wise. Even if we improve our league position, we are likely to be worse-off in the CL (I hope we progress, of course), which will hurt us financially. Our injuries also impact our sporting prospects, whilst severely altering what priorities (and what resources) we have for the winter transfer market. I don't exactly see this grand improvement.
I disagree with you on many things, but most importantly, Pioli has to take more responsibility for the problems that have been put onto Maldini's shoulders, because he's not here anymore.
We still are showing the same worrying signs of play that existed in the first half of last season that I did not recognize as a problem last year--and maybe it changes this year? Maybe we grind out things and hit form again? I hope we do. Even great teams do that, but again, all the work done in the summer and tactical shifts have been abandoned (like the previous year under Pioli) where we have reverted to dribbling, individual moments rather than constructed plays (for the most part), an ad-hoc rotation system (mostly forced... by injuries) that has resulted in more injuries in-game, all while we have suffered more muscular injuries than ever before under Pioli.
An injury record, I'd like to add, that is worse under Pioli than it was under previous regimes.
I think this squad can do much better than it has, that's why I am upset. If I thought we were only a 3rd place team, I would be satisfied. I do not think that is the case.
