Not much, they will just try to win more match and collect points and qualify for the Champions League next season again. I don't think Juventus can win the title this season because the difference in points with Inter is quite a lot. Getting into the top 4 or at least ending the season in 3rd place would make sense for Juventus.
Juventus will win the title if they do some amazing matches in rest of season and if their opponents above lose too many points. With so many conditions that are all difficult to occur and more difficult to see they occur together, it is very impossible for Juventus to win Scudetto. Anyway, they will have to fight at best to be qualified for the third or fourth position in Serie A.
I'm more interested in knowing what AC Milan really expects this season if not the title. They still have hope of getting him from Inter, but his good form has to improve. Milan is expected to beat Inter in the next match because this will be an important match to make their chances even better.
AC Milan and Napoli look like don't have enough components to win the trophy. Inter Milan have such but let me say, I am not Inter Milan fan. Then Inter Milan will have best resource and experience in this competition. They are not only champions but also have others (resource with better substitution, and more experience). AC Milan and Napoli have less experience and their second team, substitutions are worse than Inter Milan.
