The 1990-91 season saw Sampdoria win the Serie A title for the first time in their history, finishing five points ahead of second placed Milan. Third placed Internazionale were victorious in the UEFA Cup, with ninth-placed Roma compensating for their sub-standard league season with glory in the Coppa Italia, while Juventus's seventh-placed finish meant that they would be without European action for the first season in three decades. Lecce, Pisa, Cesena and Bologna were all relegated.
Associazione Calcio Fiorentina enjoyed its best season in the 1990s on the pitch, but was left wondering what might have been. Leading the domestic Serie A championship a long way into the season, Fiorentina's title charge fell to pieces, as it lost unnecessary points while eventual champions Milan and runners-up Lazio continued winning their matches. In the end, Fiorentina salvaged third place in the league, qualifying for the UEFA Champions League in 1999–2000.
The 2010–11 season was ACF Fiorentina's 85th season in Italian football and their 73rd season in the first-tier, Serie A. This was also the sixth consecutive season for the club in the top-level division of the Italian football league system.
The 2005–06 season was ACF Fiorentina's 80th season in its history and its 68th season in Serie A. The club had its best season on the pitch since the 1998–99 season, originally finishing 4th with 74 points and securing a spot in the qualifying round of the 2006–07 UEFA Champions League. However, the club was punished with a 30-point penalty for its involvement in the 2006 Italian football scandal, resulting in Fiorentina being pushed down the table to 9th. This was a much better outcome than its original punishment, as La Viola were originally relegated to Serie B. Following a successful appeal, Fiorentina was admitted to play in Serie A the following season, albeit losing its Champions League slot and having to start the season with a 15-point penalty, removing any chance of mounting a genuine title challenge and building on the success of the 2005–06 season.
Parma Associazione Calcio once again troubled the top teams in both Italy and Europe, but had to settle for just the curtain-raising UEFA Super Cup as silverware in its ambitious ascent towards the top of Italian football. It almost repeated the victory in the 1992–93 UEFA Cup Winners' Cup by reaching another final, but lost out to Arsenal.
Associazione Calcio Fiorentina failed to take off under former Brazilian national team coach Sebastião Lazaroni, and ended the season in 12th place. The result prompted president Cecchi Gori to sign German starlet Stefan Effenberg among others for the coming season, also replacing Lazaroni with Luigi Radice. The most significant event in Fiorentina's season was the arrival of Argentinian striker Gabriel Batistuta, who was to become Fiorentina's all-time topscorer during his nine years at the club.
Parma Associazione Calcio eased through the infamous second season following promotion, and ended it in style by winning Coppa Italia, the club's first ever significant silverware. That also qualified the club for the 1992–93 UEFA Cup Winners' Cup, a tournament it went on to win. Its inaugural European adventure was in the autumn of 1991, when it lost to CSKA Sofia of Bulgaria in the first round of the UEFA Cup. It did not improve on 1991's famous fifth place in Serie A as rookies, but only slipped one position, with the defence playing as well as ever. The lack of a top scorer cost Parma the chance to fight Torino for third in the championship.
Parma Associazione Calcio played its third consecutive season in Serie A, and had arguably its best ever season, even when considering its glorious years in the late 1990s. It finished third in the domestic league competition and won the UEFA Cup Winners' Cup following a 3–1 final victory against Royal Antwerp.
Parma Associazione Calcio played its sixth consecutive Serie A season, which was the last under legendary coach Nevio Scala, who stepped down at the end of the season. Defensive stalwarts Alberto Di Chiara and Lorenzo Minotti also left the club following the season's conclusion. Despite being only one point behind third-placed Lazio, Parma finished 6th in the standings. In contrast to the previous four seasons, Parma did not win any cups either. The most significant moment of Parma's season was the debut of the club's new superstar, 17-year-old goalkeeper Gianluigi Buffon, who saved a penalty on his debut against A.C. Milan.
A.C. Fiorentina finished in the midfield of Serie A, beating Roma 1-0 in a playoff match due to a goal by ex-Roma player Roberto Pruzzo. The season also marked the international breakthrough of Roberto Baggio, the striker scoring 15 league goals, also setting up several of Stefano Borgonovo's 14.
U.C. Sampdoria won their first ever Serie A title, thanks to a remarkable season for a team playing on its absolute peak. Gianluca Vialli was the league top scorer on 19 goals, and Roberto Mancini, Attilio Lombardo, goalkeeper Gianluca Pagliuca plus centre half Pietro Vierchowod were also instrumental in Sampdoria's success story.
A.C. Milan did not defend their European Cup title for a second consecutive time. The second place in Serie A was the fourth consecutive season when Milan finished inside the top three of the league. The loss in the European Cup quarter-finals rendered a first trophyless season since 1987, which resulted in Arrigo Sacchi leaving his job to take over the national team, being replaced by ex-Juventus and AC Milan midfielder Fabio Capello.
Associazione Sportiva Roma won the Coppa Italia and reached the final of the UEFA Cup, which compensated for Ottavio Bianchi's problematic league season, where Roma finished a mere 9th place, their worst season since 1979.
Juventus Football Club had their least successful season since finishing 12th in the Serie A back in 1961–62. This time, under Luigi Maifredi's coaching, Juventus finished 7th, despite breaking the World record in terms of transfer fee, to bring in Fiorentina star striker Roberto Baggio. Being long involved in the Scudetto race, Juventus lost the plot in the second half of the season, barely winning a match in a ten-game spell, which caused the side to drop down to the upper midfield.
The 2011–12 season was the 112th season in Società Sportiva Lazio's history and their 24th consecutive season in the top-flight of Italian football.
The 2014–15 Coppa Italia, also known as TIM Cup for sponsorship reasons, was the 68th edition of the national cup in Italian football. Napoli were the defending champions, having won the previous year's final, but were eliminated in the semi-finals by Lazio. Juventus emerged victorious with a 2–1 win in extra time, achieving a record tenth title.
The 2014–15 season was Atalanta Bergamasca Calcio's fourth consecutive season in Serie A after having been relegated to Serie B at the end of the 2009–10 season.
Associazione Calcio Fiorentina had a poor season, finishing 16th in Serie A and being relegated to Serie B as a result. The highlight of the season was a crushing 7–3 defeat suffered at home to eventual champions Milan. The season would also see four different managers at the helm.
The 2017–18 Coppa Italia, also known as TIM Cup for sponsorship reasons, was the 71st edition of the national cup in Italian football. As a minimum, the winners of the Coppa Italia earn a place in the 2018–19 Europa League and would begin play in the group stage unless they qualify for a more favourable UEFA placing based on league play. Seventy-eight clubs participated in this season's cup competition.
The 1990–91 season was the 91st season in the existence of S.S. Lazio and the club's third consecutive season in the top flight of Italian football. In addition to the domestic league, Lazio participated in this season's edition of the Coppa Italia.
