Juventus defender Andrea Barzagli feels that the success of his side is built around their defending.
The Serie A leaders take a 3-0 lead into the second leg of the Champions League clash with Celtic on Wednesday.
Barzagli told reporters: "The basis of our defence is organization. We have been working hard even in the few days we've had [since the Napoli match].
"There is a great harmony in this group. The midfielders and attackers also give us defenders a big hand. We are a compact team that works hard. We have a solid foundation and we hope that continues to be the case."
Juventus hold a six-point lead over second-placed Napoli at the top of Serie A.
