Palermo president Maurizio Zamparini has claimed that Paulo Dybala is the "only world-class talent" that Juventus have in their ranks.
Zamparini sanctioned the sale of Dybala to Juve this summer, with the Argentine joining the Italian champions on a long-term contract.
The Old Lady have lost both of their first two league games this season, however, and Zamparini has hinted that there could be problems ahead.
"Dybala is the only world-class talent that Juve have," the Palmero president told reporters.
Dybala has scored twice in three games for Juve this term.
