"My emotions will be running high on Sunday," said the striker who wore the Viola jersey from January 2005 to January 2009.
"In football everyone takes their own path and I'm sure that the moment the referee blows his whistle to start the game, I will only be thinking about playing."
'Il Pazzo' is famous for his goal celebration where he holds his hand in front of his face and points to his eyes.
"That started in Florence with Toni. He would put his hand to his ear, so in contrast I'd point to my eyes. We were basically making fun of each other in a nice, friendly way."
