The Bianconeri face Barcelona at Camp Nou and still have a slight chance of winning the group.
“We must show the attitude that gave us the win in the derby," Bonucci said. “An aggressive team that knew what we had to put on the pitch to get the win.
“I hope that the second half of the derby is the beginning of a new path that is difficult.
“Tomorrow, we play against a great team, but these matches are stimulating our growth."
He added: “The most important thing is to have seen the reaction in the second half of the derby. It means that we have this attitude inside and we must put it into every game.
“In these days, we have had some time to train, we talked about the ingredients to play a great match. A positive result would accelerate the team's growth path."
