AC Milan is one of the most successful football clubs in Italy, having won numerous Serie A titles and European Cups. One player who has had a significant impact on the club's success is Theo Hernández.

Hernández joined AC Milan from Spanish club Barcelona in January 2017 for a fee of €40 million. He was immediately given the number 9 shirt and was expected to be a key player for the club.

In his first season at AC Milan, Hernández scored 16 goals in all competitions, including 5 goals in Serie A. His performances were so impressive that he was named the Serie A Player of the Month in March 2017. However, his form dipped slightly in the following seasons as he struggled to find the net regularly.

Despite this, Hernández remains a key player for AC Milan and has made several important contributions to the team over the years. In 2018, he helped the club win the Europa League by scoring two goals in the final against Atlético Madrid. He also played a crucial role in the team's successful campaign in the 2019-20 Serie A season, helping them finish second behind Juventus.

However, despite his impressive record, there have been criticisms of Hernández's performance at AC Milan. Some fans have criticized him for not being consistent and for failing to live up to his potential. Additionally, some critics have suggested that his signing was a mistake for AC Milan, given the high cost of his transfer.

Overall, Theo Hernández has had a significant impact on AC Milan, both on and off the pitch. While his performances may not always be perfect, he remains a valuable player for the club and has contributed greatly to their success over the years.
