Context paragraphs:
1994–95 S.S.C. Napoli season: S.S.C. Napoli performed about the same as it had in the 1993-94 season, finishing seventh in the championship, but having a better domestic cup run.  Napoli also reached the Last 16 of the UEFA Cup, where it lost to Eintracht Frankfurt.  The squad had been depleted due to losses of several offensive key players in the seasons before, so seventh in the domestic league would normally have been regarded as a positive result, but it was only after Vujadin Boškov had been appointed to lead the team in place of Vincenzo Guerini that Napoli could stay well clear of the relegation zone.  Brazilian signing André Cruz was crucial to the defense, and also showed unusual offensive skills for a central defender, scoring several goals.  Fabio Cannavaro also had a spectacular season, which ended with Parma buying the defender.

Derby del Sole: The Derby del Sole, (English: Derby of the Sun), also known as Derby del Sud, is an Italian football derby between S.S.C. Napoli and A.S. Roma.  The two clubs are considered the most followed and successful outside of Northern Italy (the heart of Italian football); Roma being from Central Italy and Napoli from Southern Italy.

1996–97 S.S.C. Napoli season: S.S.C. Napoli continued its steady decline with another lacklustre season.  Once more, goalscoring was at a premium, with only 28 goals being scored in the 34 league games.  Coach Luigi Simoni was sacked and replaced by youth team coach Vincenzo Montefusco, who led the team to the Coppa Italia final against Vicenza, where Napoli won at home thanks to Fabio Pecchia's goal, but lost 3-0 away from home, and therefore failed to win the trophy.  The 13th place in the domestic league was the worst for 14 years, and one year on, Napoli was ultimately relegated.

1992–93 S.S.C. Napoli season: S.S.C. Napoli got extremely close to a shock relegation to Serie B, and only held on to its top-flight status by two points.  This was just three years since the club led by playmaker and legend Diego Maradona won the domestic league title.  It actually spent Christmas of 1992 in the relegation zone, and climbed out of it thanks to a strong January '93 run.  The reason Napoli survived was the above-average offensive skills.  Gianfranco Zola, Daniel Fonseca and Careca was a trio capable of leading any teams' attack, and the club looked set to suffer when Zola (Parma) and Careca (Japan) departed at the end of the season.  Fonseca's season is mostly remembered for an extremely unusual five goals in one match, as Napoli beat Valencia 5-1 away from home in the UEFA Cup.  Then it lost to Paris SG in the next round, rendering it was out of Europe.

2001–02 S.S.C. Napoli season: S.S.C. Napoli spent the 2001-02 season in Serie B, which had been assured following sensational events in the final Serie A round the season before, when all bottom teams won their matches.  In 2002, Napoli came fairly close to promotion, but stumbled due to a 2-1 defeat to Siena at the end of the campaign.  With Empoli rounding off their campaign with a victory, not even a win could have helped Napoli to have a chance, and with the team also losing the final game of the season, Luigi De Canio stepped down as coach.

1985–86 S.S.C. Napoli season: S.S.C. Napoli had its best league season in five years, finishing third in the 1985-86 league season.  Due to Roma's collapse in the final rounds of the season, Napoli closed to within two points of second place, also having a significant margin to Torino in fourth.  Diego Maradona prepared for his glorious World Cup with eleven goals and several assists.

1993–94 S.S.C. Napoli season: S.S.C. Napoli once again struggled to reach the levels it had under Diego Maradona's spell at the club, but finished a respectable sixth in Serie A, which landed Marcello Lippi the Juventus vacancy, something he put to good use.  Financial woes caused Napoli to sell its two prominent foreign players, Jonas Thern and Daniel Fonseca to Roma following the season's end.  Skipper Ciro Ferrara also left, in his case for Juventus.

Daniel Fonseca: Daniel Fonseca Garis (born 13 September 1969) is a Uruguayan former footballer, now a football agent.  As a forward, he notably played for Italy's S.S.C Napoli, A.S. Roma and Juventus.

1997–98 S.S.C. Napoli season: S.S.C. Napoli crashed out of Serie A following a disastrous season.  It only clinched 14 points out of 34 matches, despite having the services of several experienced Serie A players.  Napoli went through four coaches over the course of the season, and hardly took a point in the second half of the season.  Given the disastrous form of the team, Claudio Bellucci's ten goals were impressive, while thought top scorer Igor Protti was one of the largest disappointments of the entire series.  The lack of defensive skills cost Napoli many points, and more than two goals were conceded on average.  This was despite Roberto Ayala's brilliance, which earned him a transfer to A.C. Milan.

Mário Rui: Mário Rui Silva Duarte (born 27 May 1991), known as Mário Rui, is a Portuguese footballer who plays for Italian club S.S.C. Napoli on loan from A.S. Roma as a left back.
