The duo have enjoyed strong starts to the season to help the Old Lady go five points clear at the top of the Serie A table after just eight games into the new campaign.
Argentina star Dybala bagged himself a brace in Juve's last outing against Udinese over the weekend and interest continues to grow around the former Palermo striker.
Former Juventus boss Antonio Conte has also been credited with interest at Chelsea for Bonucci and Marotta feels the club could look to tie down the pair to fresh terms at the Turin outfit.
He said: "The renewals of Bonucci and Dybala? They are already well paid players, but it is right to give them recognition. We are working to adapt their contract also in order to maintain balance in the dressing room."
