don't be acting now like a complacent douche
Inter have a very good group of players - more than enough quality there to win the scudetto - their season will be determined by whether Stramaccioni can get out of them what they are capable of or not.
Juve's so called "world class" players aren't exactly world class but it's the system/Conte that brought out of them more than they would have likely shown in a different team/set-up.
All in all, Strama has a squad more than capable of winning the title, especially with no CL to worry about (expect them to crush out of EL pretty soon) ... it would depend entirely on his ability to put them into a team.
Juve, on the other hand, would have to face different circumstances this year - there will likely be more injuries (let's face it last year you had virtually 0 of those), CL to take care of; with success, complacency is also likely to become part of the picture now and then, and players could lose the motivation and concentration they had last year, etc, etc.
in short, it will be a long season and it don't matter how you start but how you finish
