The 2003-04 campaign delivered a triumphant return for Cagliari as Casteddu secured a crucial 2nd-place finish in a famously controversial and expanded Serie B, achieving promotion back to the top flight after four seasons. Leading the charge was the prolific David Suazo, whose 19 goals proved decisive, anchored by the inspirational presence of returning legend Gianfranco Zola, who captained the side. The promotion, secured with two games to spare, marked a watershed moment that restored the club to Serie A and remains a cherished chapter in their history.
