Palermo owner Maurizio Zamparini has had a pop at Juventus striker Paulo Dybala.

Zamparini sold Dybala to Juve three years ago.

“He's going through a rough patch, but it's no cause for concern," Zamparini, who brought the 24-year-old to Europe, told Corriere dello Sport.

“It's something that everyone goes through, especially those who go from earning €400,000 to €10m a year. It's not something to laugh about.

“He still doesn't know that happiness doesn't lie in money, and this has possibly caused some decompensation, but he's a smart lad and he'll come out of it.

“I have no advice to give Marotta and Allegri, who are doing well. They just have to wait for Dybala and let him get his enthusiasm back.

“it'd be a mortal sin if he lost it, I had players, like Ilicic, who had great ability, but only if they played with enthusiasm."
