The Nerazzurri travel to Turin looking to close a four-point gap on the leaders, who are unbeaten in 49 league games.
Milito believes that Inter are showing signs of challenging Antonio Conte's men this season, but admitted that it will be hard to do so should they continue their ruthless form.
"We are in good shape and we are confident that we will go to Turin to play a good game and cause them problems," the Argentine international told Tuttosport. "The game itself will tell us whether we are the anti-Juventus.
"We are certainly on the right road, but we still have to grow. In the meantime, we are having an excellent campaign.
"It's an important match, but not decisive. We are only in Week 11. The four-point gap is not a lot and it is not little. Juventus are having an extraordinary season and, if they continue like this, then it will be hard to catch them."
Milito has scored five goals in 10 Serie A games this season.
