As Milan prepares for their crucial Serie A Round 4 match, the starting lineup is a mix of seasoned veterans and rising talents, aiming to maintain their momentum in the league. Here's a breakdown of the likely starters and the tactics they might employ.

**Key Players:**

1. **Donnarumma (Goalkeeper):** The first-choice goalkeeper, Donnarumma, is a certainty in goal. His command of the box and distributive skills make him indispensable.

2. **Thiago Motta (Center-Back):** As a defensive anchor, Motta's experience and composure will be vital. His presence ensures organizational stability in defense.

3. **Jean-Georges Balbuena (Center-Back):** Known for his strength and aerial ability, Balbuena complements Motta well, providing a solid defensive partnership.

4. **Hakan Calhanoglu (Midfielder):** A creative force, Calhanoglu will likely start in midfield, using his vision and through balls to break down defenses.

5. **Sandro Tonali (Midfielder):** Another key midfielder, Tonali's technical ability and work rate make him a pivotal player in controlling the game's tempo.

6. **Ibrahimovic (Forward):** Although sometimes rotated, Ibrahimovic's presence up front can't be overlooked. His ability to hold up the ball and score crucial goals is invaluable.

7. **Rafael Leao (Forward):** With Ibrahimovic potentially on the bench, Leao's speed and dribbling could see him starting, offering a different dimension to Milan's attack.

8. **Diaz (Wing):** Diaz's pace and directness make him a favorite for the left wing, where he can exploit defensive gaps with precision.

9. **Divorté (Wing):** Likely to start on the right, Divorté's versatility and work ethic provide width and an attacking threat.

**Tactics:**

Milan's approach under Pioli is characterized by high pressing, quick transitions, and an emphasis on overlapping full-backs. The midfield trio of Motta, Calhanoglu, and Tonali will look to control the game, with Motta screening the defense and the others providing attacking intent.

Defensively, Milan will adopt a compact structure, focusing on preventing counter-attacks. Full-backs are encouraged to join the attack, adding to the wings' overload and creating numerical superiority.

In the final third, the onus is on Calhanoglu and Tonali to create chances, utilizing quick one-twos and incisive passes. Milan's ability to adapt to different opposition will be key, as they aim to exploit weaknesses in a high-stakes match.

This lineup and strategy reflect Milan's blend of experience and youth, as they seek to climb the league table. With a balanced mix of stars and rising stars, Milan is poised to deliver a strong performance.
