This season is best one for Juventus to lift Scudetto again because they only play in Serie A and can take advantage of it to beat Inter Milan through a long season. Inter Milan are strong and stands at the first position but they might be affected more by Champions League matches in coming months. In contrast, Juventus won't have that distraction and with 100% focus on Serie A, they will potentially play better than Inter Milan and win the league.

I wrote a long time ago that Juventus has an advantage in that they concentrate on one tournament, while competitors during the playoff stage in European competition will give their maximum effort there and play “on a residual basis” in Serie A.
Bookmakers also greatly overestimate Inter now - I agree that Inter is the favorite, but before a personal meeting with Juventus (second), based on statistics (they really have the best in Serie A), giving them the title with a 70% probability is too unfair.
