AC Milan's friendly match against Celtic provided insight into the team's defence strategy, particularly with Mario Gila's deployment as a right-sided centre-back, or 'braccetto'. This tactical move was not an accident, but rather a deliberate choice linked to Samuel Chukwueze's position as the right wing-back.

Gila's role as a centre-back allowed Chukwueze to push forward, taking advantage of his pace, one-on-one play, and overlapping and underlapping runs. However, this new version of Chukwueze still needs to improve his defensive skills, including positioning and success in duels.

Ruben Amorim's decision to deploy Gila as a centre-back was a calculated move to capitalise on his pace, aggression, and ability to intervene in open space. This move also highlighted the potential deficiency in the middle, where Matteo Gabbia struggled during the match.

To complete the defence, Amorim is searching for a central defender who can receive the ball under pressure, puncture the opposition press with their passing, and perform defensive tasks well. Examples of potential targets include Gonçalo Inacio, Jorrel Hato, and others.
