Before he arrived at Roma Paulo Dybala was an already established phenomenal attacker jus that he wasn't at his best in his final season at Juventus which is why many believes it was Jose Mourinho who helped the Argentine to be back to his best.
That being said, the player still has the independent privileged to determine his future at wether to continue playing for Roma or consider a move to another club. The summer transfer window is still very much open and anything can happen before the last day of the transfer window
As there is still independent privilege with Paulo Dybala, he should be able to make the right decision for himself at this time before the transfer window closes because next season he will also have to do better by being in a more right team, even though he won't either. it would be wrong if he had to return to stay at AS Roma next season because Roma is also not a bad team for him with almost 30 years of age.
