The 2014-15 campaign was a season of ultimate heartbreak and chaos for Cagliari as Casteddu plummeted to a crushing 18th-place finish in Serie A, resulting in relegation to Serie B after eleven consecutive top-flight seasons. The year was defined by unrelenting managerial instability, with the club cycling through four different coaches: Zdeněk Zeman, Gianfranco Zola, Zeman again, and finally Gianluca Festa. Despite the turmoil, local forward Marco Sau battled to lead the line, with his 7 league goals proving a crucial tally in a season built on the determined but ultimately unsuccessful efforts of the squad, led by veteran captain Daniele Conti. It was a dark, turbulent year that marked a painful but defining chapter in the club's history.
