The two teams meet in Riyadh later today, with Lazio having thumped Juve a fortnight ago.
“That game taught us that incidents can be really decisive," said Bonucci in today's press conference.
“We're well aware that Lazio are in great shape, but we too are coming off a run of positive performances and results, so we're confident as well.
“Our initial objective is to do better than the last time we played Lazio, where we allowed them too many scoring opportunities. A win here would increase our enthusiasm and confidence, so we hope to go into the Christmas break with another trophy on the mantelpiece."
He added: “It does irritate us that we're conceding so many goals and many are down to individual errors, others part of a growth process with this new approach. We know that we have to improve."
