The Italy defender has heaped praise on the Bianconeri's rearguard after a run in which Antonio Conte's troops have conceded just one goal in their last eight Serie A games
The clean sheet at the Artemio Franchi means that the Bianconeri have now conceded just once in their last eight Serie A outings.
Consequently, Bonucci believes that the Old Lady's defence deserves as much credit for their Scudetto challenge as their attack.
“It’s certainly an added value," the Italy international is quoted as saying by the club's official website.
"We’ve conceded one goal in eight games and I think our impenetrable defence is one of the secrets of this Juve side.”
Bonucci also hailed the entire team's concentration and humility, revealing that they have already turned their attention to Wednesday's clash with Lecce after moving to within two victories of the title courtesy of their rout of Siena.
“We spoke in the dressing room and knew it would be another tough game like we faced in Cesena [in midweek]," the centre-half explained. "We took to the field with the right focus, possessing the hunger of those who want to win.
“We instantly managed to get things going in our favour, and did well to immediately put the game to bed.
“It was a good victory that’s come from a great team, a great manager and a great project. We’ll now think ahead to Wednesday, because we still haven’t achieved anything.”
Juve's meeting with relegation-threatened Lecce gets under way at 20.45CET.
