AC Milan is one of the most successful clubs in European football, with a long history and a rich tradition. One of the key elements that has helped them achieve this success is their top-notch defense.

One of the standout players in AC Milan's defensive line-up is Alessio Romagnoli. He is a young Italian defender who has already made a name for himself on the international stage. Romagnoli is known for his strong tackling skills, excellent positioning, and his ability to read the game well. His work rate is also exceptional, as he often plays the full 90 minutes of every match.

Another player who stands out in AC Milan's defense is Antonio Rudiger. The German defender is known for his versatility and his ability to play both at centre-back and as a right-back. Rudiger is a solid defender who can read the game well and make crucial interceptions. He is also known for his physicality, which allows him to dominate the midfield and prevent opponents from creating space.

Finally, we have Andrea Barzagli, another Italian defender who has been a regular member of AC Milan's team since 2015. He is known for his strong headers and his ability to clear balls from dangerous positions. Barzagli is also a good passer and can contribute to the team's offensive play when needed.

Overall, AC Milan's top defenders are all talented players who are committed to giving their best every time they take the pitch. Their ability to defend effectively is one of the main reasons why they have achieved so much success over the years.
