Al-Khelaifi, however, has denied the 24-year-old is seen as an important target for PSG.
"The truth is there are a lot of good players in Serie A, not just Dybala," he told La Stampa. "If we are interested in him, we'll call Juventus.
"[Juve president Andrea] Agnelli is a good friend but I can tell you that Dybala, at the moment, is not the key to PSG's future."
Al-Khelaifi also denied that PSG are considering replacements for head coach Unai Emery.
Chelsea boss Antonio Conte and former PSG coach Carlo Ancelotti are among those to be linked with the club, but Emery's job appears safe for now.
"You have excellent players, excellent clubs and excellent coaches in Italy. But, for now, we're happy with Emery," said Al-Khelaifi.
