Compared to a team like Juventus, I think you are right and AC Milan is a good team in the Serie A. They were always in the good form. However, the fact about AC Milan and some other teams in the Serie A is they are still not close to Inter Milan and during the last two years, they were far better than other teams. At the same time, they also hired some players to be better performers than last season which means they aim for the Champions League.
I agree with you. So far I think Inter Milan will still dominate Serie A this season. I see AC Milan and Juventus have made several important player transfers but Inter Milan have not made any significant transfers. Davide Frattesi is Inter's most expensive purchase this season with a value of €29 million. Overall Juventus, AC Milan and AS Roma will be able to perform well this season but I doubt if they will be able to compete with Inter Milan. But I hope Serie A can be more competitive because it seems like it will be boring if only one team dominates the league.
Juventus, Roma, and Ac Milan are not happy with the fact that the Inter Milan team became suddenly stronger and formidable as a team last two seasons than were, so there's a need for these teams to strengthen their squad, and for the Inter Milan side, it is not necessary that they sign in a number of new into the team when there is no need for that, However, I'm eagerly awaiting to see a more competitive Serie A league this season between Inter Milan side, Juventus, AC Milan, and As Roma way more interesting than how last season were.
Milan, Juventus and Roma will probably be the clubs that continue to try to get the Scudetto even though in reality Inter Milan has better quality players' performance and maybe we also need to add Napoli as a strong challenger for Inter Milan because currently the club is handled by a very experienced coach and there is still Osimhen who can be relied on.
It might seem boring or unfair to other clubs if Inter Milan has to dominate the Serie A title but in reality Inter is currently more confident with all of its current players who are still quite confident in facing the competitive challenges in the new season.
The reason for not making a transfer is probably most people already know if Inter Milan does not want to lose confidence to continue to improve the club's performance to pursue the Serie A title and other prestigious titles.
