Bonucci also said that Juve were not thinking about lifting the Serie A title until they achieve the points required to win it.
"In the reverse fixture, we lacked concentration, motivation and energy, which are all vital traits at a club like Juventus," the club's official website quotes him as saying. "Since then, we have been growing as a side and have become very consistent.
"We're up against an in-form Milan team, as is shown by their results in 2013. Along with the memory of defeat in the reverse fixture, this will give us extra motivation for Sunday because not only do we want to get our own back on them but we're also looking to take another step towards Scudetto triumph."
"We'll leave our final analysis until after we've achieved our objective. For the moment, we have to be on the ball until we're mathematically certain of being Italian champions."
The match kicks off at 2pm on Sunday.
