Juventus capitalised on AC Milan's slip-up against Bologna earlier on Sunday to move three points clear of their title rivals with an impressive victory in Turin.
The Old Lady have won their last six and remain unbeaten in the league this season. Buffon puts the incredible run down to their defensive record.
"I've conceded just once in the last seven games and just 15 in the 31 games I've played. Something like this has never happened before, not even in the years when we dominated as a side," the 34-year-old stopper told the club's official website.
"The defensive solidarity is the platform on which we've built our successes."
Juventus continue their title charge at Cesena on Wednesday.
