Same changes should be applicable in Inter Milan. Inter would have done far better last season if only the squad they used were good enough. The players from last season tried but how it ended shows they had many difficulties to be corrected by new signings. Now they signed a new manager what about ensuring that new players are brought in alongside the new coach. Looking at Inter Milan squad, the players are aged enough that they need to retire or move out from the Italian league.
This suggests that next season's Serie A competition should be as strong and competitive as it was, given the changes made to the clubs and the relative decline of the top clubs. Furthermore, they are currently working to improve their performance, both as a team and individually.
Some of them are like what AC Milan is currently doing, which is trying to rebuild its glory days after getting Allegri.
I doubt this would happen. I know that people assume next season should see more teams fighting for a title but it is not going to be that easy or at least that quick for teams to get this much better over course of one summer. Inter and Napoli were both great, Juventus was decent but not near the top, and Milan was far off from the top without even a chance.
So thinking Juventus may get better and close, is reasonable and understandable but may not happen, but assuming Milan would be better? They can't be near the top this quickly after such a horrible season. They should be looking into getting better of course, but not that much better, being top four would be more than enough success for them, finishing fourth is the goal here.
