Juve has a very bad squad, they also lost Ronnie +25 goals and replaced him with no one, Morata is a scrub, Dybala is still living of 2017 hype and Chiesa is the only good one but is still too inconsistent and doesnt have enough output to carry a whole team in his back.
I think the Milan teams + Roma (if Mou doesnt lose the dressing room) are the contenders this year.
I would rather put my faith in Chiesa than in Dybala, if i was a Juventus-fan.
Dybala have spells where he just isn't up for it, Chiesa is younger and has something special about him.
