Inter Milan and Napoli they have to prepare for the Champions League next season. So it's not surprising that they really take advantage of the player transfer market quite well. Meanwhile, for AC Milan, they are also preparing their team as best as possible because they don't want to repeat the same failure as last season. AC Milan definitely wants to be able to compete again at the top of Serie A. So they have to make their squad worthy of this. They also have to support the new coach they have very well, namely by bringing in new players who can also be expected to improve the quality of the team.

However, it seems that many other teams in Serie A are not very active in bringing in new players. Or maybe they're just not in a hurry.
