Serie D is the fourth tier of professional football in Italy. It serves as a crucial step for clubs aiming to reach higher divisions, such as Serie C. The league is divided into several regional groups, allowing teams from different areas to compete against each other. Each season, the top teams from these groups can earn promotion to Serie C, while the lower-ranked teams face the risk of relegation to amateur leagues. Serie D is known for its passionate local fan bases and serves as a platform for young players to showcase their talent and develop their skills.
