Juventus coach Max Allegri regards Roma as their nearest challengers.
The Bianconeri are going for a seventh Serie A title in a row.
"This year will be a much more difficult season because all our rivals have strengthened," Allegri told Premium Sport.
“It will be complicated to win the seventh consecutive Scudetto, but that's our primary goal for the season.
“Last year Roma got 87 points, their historic record, and therefore they're our main rivals.
“But Napoli, Milan and Inter will also fight for the Scudetto, and don't rule-out Lazio."
