The two teams meet at the Juventus Stadium, where the hosts have won all 10 of their league fixtures this season, and Campagnaro admits that the Bianconeri are the strongest side in Italy.
"I always remember tough games against Juve," he told the Il Corriere dello Sport. "In recent years the Bianconeri proved they are the best side in Italy and are doing extraordinary things.
"Just take the 1-1 draw with Lazio, as they were a goal down and with 10 men, but still avoided defeat. Juventus never give up.
"They have a good advantage and in the head-to-heads with Roma and Napoli proved they've got another gear. They are too much stronger than the rest."
Inter are currently sixth in the Serie A table.
