7 Serginho

Serginho was a fringe player who was frequently used as a substitute in his early years, but developed into a complete center-back and reached the pinnacle of his career; his best performance came in the Milan derby, and he has been a worthwhile player for the club since then.

He was also a hero in the 2003 Champions League victory over Juventus, scoring the

game-winning penalty. During his nine years at the club, he appeared in 185 games.

6 Kakha Kaladze

In 2001, Italy made one of the most expensive signings to bring the Georgian player to Italy, and the player was promptly made the club's priority center back. Kaladze's outstanding showing in Series A led to Georgia issuing a special stamp in his honor, and he was the first Georgian player to win the Champions League.

His stability as a center-back saw him make 284 appearances for the club and form a

formidable defense in AC Milan.

5 Alessio Romagnoli

Imagine making 40 appearances for one of Europe's most prestigious clubs; it's not

everyone's cup of tea, but Romagnoli made it look effortless and was a standout defender in their history. For the first time since 2007, Milan advanced to the Coppa Italia final thanks to his goal in the final game.

He had a glittering career at the club, appearing in over 40 games in six seasons and totaling 247 appearances.

4 Ignazio Abate

Few players have managed to ingrain themselves in AC Milan and become one of the finest defenders in the club's history; fortunately, Abate was a spectacular defender and was offered a long-term contract after wowing then manager, Leonardo, and starting 35 games as a loan player.

In his 15 years at the club, Abate made 305 appearances before joining Napoli on loan and winning Serie A in 2010.
