He is an excellent passer when he has runners in front of him.

Our overall play as a team has deteriorated massively since the second half of 2016/17.
And Dybala has stopped looking to pass, the vast majority of the time, unfortunately.
Stop trying to make out that Dybala's poor season is 100% on Allegri. It's not. He has a pretty poor attitude and sulks around the pitch half the time, instead of working to get better.
Maybe he could fix his first touch. Maybe he could look up once in a while when he has the ball around the box, and notice that Ronaldo is on the pitch too. Maybe he could work on strengthening his weak foot. Etc etc.
Allegri has to bear some of the responsibility... I think the archaic fitness training methods we seem to have been using the past 2 seasons have left Dybala in fairly rough physical shape, and I definitely think Allegri could have tried playing Dybala further forward in a front 2 as the support striker far more often, especially last season with Higuain, and Costa in scintillating form on the wing... 4-4-2 might have been fantastic last year with Dybala further forward instead of playing in the mid.
I also think Dybala would look better if Beppe and Paratici hadn't destroyed any semblance of midfield strength we once had over the last 4 years. If we can afford to strengthen the midfield significantly (and backline) while keeping Dybala and Costa, and have a creative technical player in there so Dybala stops needing to drop so deep, I hope we do so.
But Paulo also needs to fix his attitude, put his head down, and get to work on improving himself.
