My prediction is a draw. Juventus is getting stronger and I cannot underestimate them because they have put up a good performance in their first three matches. On the other hand, Inter still possess the qualities that Inzaghi has put in them, they can use that to outplay Juventus despite that they have a new coach.
For now I favor Juventus the reason is because the performance looks more consistent and they play at home while Inter Milan is in the opposite situation, but this is just a personal prediction not for betting, we know that sometimes matches in Serie A are full of drama I mean surprises can happen at any time also allegations of match fixing 
I won't be placing any bets here, just watching. By the way, are you confident that Juventus will compete for the title this season? In the last 5 seasons, Juventus' best achievement was finished in 3rd place and currently their mainstay player Dušan Vlahovic seems to be on fire, I'm not sure he can do it alone I mean Juventus needs another mainstay player who stands out more.And the match against Inter Milan won't be easy. This is a match between two top Serie A teams, where anything can happen. Both teams are quite evenly matched this season, so I think the odds are similar, with Juventus slightly favored because they're playing at home.
