The 2017-18 campaign delivered a tense, successful fight for survival for Cagliari, with Casteddu ultimately clinching a crucial 16th-place finish in Serie A. The season was characterized by an early managerial change, with Diego López replacing Massimo Rastelli in October to steady the ship. Leading the charge for safety was the prolific forward Leonardo Pavoletti, who arrived late from Napoli for €12M and notched 11 vital goals, anchoring the attack with his aerial power. It was a year of grit and determination, featuring the emergence of future midfield star Nicolò Barella, and played out in the club's temporary home, the Sardegna Arena. This hard-fought campaign secured the club's top-flight status and remains a defining chapter built on resilience.
