The World Cup winner explained that he was struggling with injuries at the time and that his "head was somewhere else" before a crucial phone-call from Antonio Conte
The veteran goalkeeper, who has subsequently won back-to-back Scudetti with the Bianconeri, explained he had felt that it was maybe time to end a decade-long relationship with the Old Lady as he struggled for fitness and focus.
"But Conte called me, telling me beautiful and important things," Buffon told Sky Sport Italia. "Since then, I am more Juventino than ever before.
"In the previous season [2010-11], the first of Andrea Agnelli's presidency, I had not played during the first half of the championship through injury and in the second half of the season I was not there; my head was somewhere else.
"I felt that it was maybe time for a change; to leave Juventus. I have always had a great sense of responsibility; [but] I had lost it.
"Then, I got to know the new directors well and they changed their opinions of me.
"Having the maturity to mend relations after some disagreements brings you together even more."
Buffon has made 359 Serie A appearances for Juventus since joining from Parma 13 years ago for a reported fee of €51 million (£43.76m).
