Juventus president Giovanni Cobolli Gigli has had a dig at AC Milan rival Silvio Berlusconi.
Asked about Berlusconi's comments about Leonardo's selection for their derby defeat, Cobolli Gigli said: "I have never taken into consideration the idea of giving advice to Ferrara.
"I am a President-Supporter and not a President-Coach."
He added: "Ferrara decides even if Del Piero is in my heart and those of all the fans. It's normal that a champion always wants to play."
