Fair play to you for always remaining positive about Juve even if we have rather strong disagreements about other things
Like you said, the biggest thing we can take from all this is that our summer mercato clearly improved this team. Regardless of all else we are better than last season's Juve, and by a clear margin, contrary to all the doom and gloom after we sold Pogba an "didn't replace him" (we did).
The last thing remaining is for Higuain to get his shit sorted out and start scoring the chances we create for him in the CL. If that happens we will be an unstoppable machine, much like Bayern 2013.
