They haven't won it yet but a win against Udinese will clinch the title mathematically. Ronaldo is a workaholic, he doesn't want to rest and is rarely even substituted out.
Juventus is playing without Pjanic for consecutive matches now. I guess they are trying out how life will be without him next year when he moves to Barca.
I think Ronaldo is still strong in the next few seasons with his age continuing.
