The Frenchman left Juventus and joined Spanish Primera Division side Hercules earlier this summer.
“Ten years with Juve was a great love story and I will forever be a fan of Juventus,” Trezeguet told BBC Sport.
“My best achievement in my 10 years was the promotion from Serie B to A, it was a fantastic experience because the fans thought those who chose to stay were heroes. I felt esteem and love.
“Around us we had kids at the time who are now major players like Giorgio Chiellini and Claudio Marchisio. If Juventus win another European title I want to be the first to wear the shirt with three stars.”
