Cagliari spent two seasons in Serie C1. In the first one it barely avoided relegation in Serie C2. In 1988, Claudio Ranieri was appointed coach, and led the team to two successive promotions, to Serie B in 1989 and to Serie A in 1990. The first two seasons back in Serie A saw Cagliari fight relegation, with safety being achieved by excellent second half runs. But the 1992–93 season would see Cagliari fight for a European place and succeed under the management of Carlo Mazzone. The following season saw a best-ever run to the semi-finals of the UEFA Cup, taking out Juventus in the quarter-finals before being eliminated 5–3 on aggregate by compatriots Internazionale, having won the first leg 3–2 at home.
