The Portugal ace is said to be unsettled in Turin and regretting his decision to quit Real Madrid for Juve 18 months ago.
Indeed, it's been suggested in the local press that Ronaldo has instructed agent Jorge Mendes to find him a new challenge.
However, Paratici has rubbished the reports and insists they're counting on Ronaldo for next season.
"Should Ronaldo stay at Juventus next season? There is no doubt about it," declared Paratici.
