Won't be too surprise if he is extending his contract for another year at Juventus. His only realistic option is PSG, but PSG has been linking up with about everyone lately - Messi, Pogba, Camavinga, Varane etc while they have also bought Ramos, Hakimi, and Donnarumma. Surely its just way too many for them. At least at Juventus, they have Allegri back, and Ronaldo is well settled in Italy too (top goalscorer), at this age, theres no immediate reason for him to leave this summer, Italy is good place for retirements, and he may not want too many changes just before the WC next year.
I do think moving to PSG would be his best option though, just for the better chances of scoring more goals and better chance for another CL trophy. But let's see.
