A report from Milan News states that the Rossoneri will have five players competing for two spots in the attacking midfield position next season.

In Amorim's 3-4-2-1 formation, the area behind Goncalo Ramos could become a major strength for the new AC Milan. There is no shortage of options for this position: Sisse, Pulisic, Loftus-Cheek and Omari Hutchinson will compete for two starting places. They have different characteristics, and the combinations are already relatively clear (at least for now). The competition on the left is mainly between Sisse and Pulisic, while in the central-right area, Loftus-Cheek will need to watch out for Omari Hutchinson's challenge. Rabiot should also not be forgotten, as he can serve as a versatile attacking option as the fifth choice.

The competition is interesting because Amorim can give the team a different look every week without changing the system. Sisse can bring energy, running and attacks into space behind the defense; if Pulisic returns to his best form, he can naturally provide technique, the final pass and especially the ability to operate between the lines.
On the other side, Loftus-Cheek provides physicality, late runs and a presence in the penalty area. Hutchinson is the more creative option: the left-footed player likes to receive the ball in the central-right area, cut inside after dribbling past opponents, and deliver the final pass or shoot directly. This is exactly the type of player Amorim had previously been looking for.
There is also Rabiot: five players competing for two positions make AC Milan harder to predict
Rabiot is another variable in the attacking midfield area. Amorim can use him in the double-pivot midfield line or push him forward into the right central area. He has already shown that he can decide matches there, such as with his goal against Torino in the opening league match.
As a result, AC Milan have five available options for the two positions. Considering the club will compete on two fronts in Serie A and the Europa League, this squad depth is crucial, especially since other areas of the team may not be as well stocked. Going forward, Amorim will need to decide who plays based on opponents and match difficulty. Rather than fixing two starters, the real goal may be to build a more unpredictable attacking line that can change its style according to opponents while maintaining balance.
