Del Piero says the striker has no limits.
He told Gazzetta dello Sport: “The kind of goal that he scored against Inter proves that he is a player of extraordinary quality. What a goal like that must do is give him even more confidence and awareness of his potential.
“In fact, I'll go one further. Someone with his capabilities, his talent and I'll add his mentality, must do even more. Paulo must set himself no limits and conquer the future.
“Nobody gives you anything for free, especially not at Juve, and I say that from experience. You have to prove everything to the very last game, let alone before the peak of your career.
“Dybala's journey has just begun and will get even better – with the Bianconeri jersey on his back, obviously."
