The Old Lady are 14 points clear of nearest rivals Roma with nine games of the season remaining but the Azzurri international praised the Giallorossi.
"The first of our ten finals has been won," Bonucci wrote on his official website. "Winning at Catania can seem easy but it wasn't like that.
"The Scudetto is absolutely not finished, hats off to Roma who are not giving up.
"Now we are playing the best form team at the business end of the season. The match with Parma is a really big one.
"We will be playing in front of our fantastic home crowd, so we will start as favourites.
"As far as I'm concerned the key words to sum up this match are 'Final Number Two.'
"We only have one goal. To win."
