"I am so happy," he told Sky Italia television. "I have reached a very important personal goal and I never thought I'd match Sivori's record when I first came to Juventus.
"The most important thing about this night is that we played a great game, proved we have rediscovered our hunger and that this team is tough.
"We are happy and tired, but at the end of the day managed to win a crucial match."
