Yes indeed but these aspects are not too different from last season. We saw De Sciglio against Manchester play a great match. He doesn't have Cancelo's sharpness to dribble and attack the final third, but in terms of passing and rotating the ball he is good.
I don't mean in terms of quality of the team in general, of course it is better now because of everyone, specially Ronaldo, but in terms of playing from the back.
IMO as bad as Alex was last season, his faults weren't so much as an outlet, but in terms of dribbling further forward, and in terms of always being late to defend and being forced to commit a fault as a result. Asamoah was always competent too.
The main difference as to how we approach midfield play when coming from the back is the presence of Bonucci. Most of his passes can be received from any of our 4 fullbacks interchangeably. It's just a tactical matter. Having him as an option takes responsibility off of Pjanic and let's us bypass midfields with long balls too.
It gives Allegri more options than with Benatia.
Chiellini is good at driving the ball forward with runs, not so much with difficult passes. Which is of course useful, just different, complementary.
