The 32-year-old international, who spent seven years at Juventus, joined Roma in 2022 and helped them reach the Europa League final in his debut season.
Dybala has struggled with injuries this season, however, including hamstring problems, and he underwent knee surgery in March, forcing him to miss nearly four months of the campaign.
"The truth is, I’d like to know something myself, but the club hasn’t approached me yet. The contract says the derby will probably be my last match in front of the Roma fans... we’ll see what happens at the end of the season," Dybala told Sky Italia.
Dybala claimed an assist as Roma beat Parma 3-2 to go level on points with fourth-placed AC Milan, a big step in their bid for a Champions League spot.
"We’ve shown the determination and desire we have to secure a place in the Champions League. We know it doesn’t depend solely on us, but we’ll fight until the end," he added.
