Pierre Kalulu is a French professional footballer who currently plays as a goalkeeper for AC Milan in the Italian Serie A. Born on February 12, 1998, in Paris, France, Kalulu began his career with Lorient FC before moving to Italy to play for Inter Milan.

Kalulu made his senior debut for Inter in 2016 and quickly established himself as one of their key players. He played a crucial role in Inter's successful campaign in the 2017-18 season, helping them win the Coppa Italia and reaching the quarter-finals of the UEFA Champions League. However, he struggled with injuries throughout his time at Inter, which limited his playing time and opportunities.

In July 2019, Kalulu joined AC Milan on loan from Inter. In his first season with the club, he made 24 appearances and kept six clean sheets. His performances caught the attention of the Milanese club, who signed him permanently in January 2021. Since then, Kalulu has become a regular starter for the Rossoneri, keeping five clean sheets in 25 league appearances this season.

Kalulu is known for his strong shot-stopping abilities and excellent reflexes. He is also a good communicator and leader on the pitch, which makes him a valuable asset for the team. Despite his young age, Kalulu has already established himself as a key player for AC Milan and is expected to continue to improve over the years.
