Former Juventus defender Nicola Legrottaglie admits Paulo Dybala is struggling for form this season.
The Argentina striker has battled for regular action under new coach Andrea Pirlo.
Legrottaglie told TMW: “First of all it depends on him and on what he believes in himself. It cannot always be the others who determine the performance of the player. This guy needs to understand what he wants to do, if he wants to set certain goals that will make him make the leap.
"With someone like (Cristiano) Ronaldo, he should take advantage of him and watch how he set up his mentality. So build your work, because with the qualities he has he could really do what he wants. And it is also a beautiful sight, when he plays."
