The 35-year-old has been with the Rome club since 2011 but, despite having faced the Serie A champions seven times in his career, he is yet to net against Juve.
However, he will have another chance when the teams face each other in Rome on Sunday, though their opponents will be out for revenge after Lazio edged them in the Coppa Italia semi-finals last season.
"I am sure that sooner or later I will score a goal against Juve. Hopefully it will happen (on Sunday)," he said.
"Besides, I am not the only person who can score goals. Our midfield is full of attacking players like Antonio Candreva and Senad Lulic. I hope to score even more this year, although I am also happy to provide assists.
"It is fundamental to play as a unit both when attacking and defending."
