Lille

First decade of glory : The War Machine (1944–1955)

Before the Second World War, the city of Lille had two clubs at the top level; Olympique Lillois and SC Fives. Olympique Lillois were crowned domestic champions in 1932–33, the very firsts in the history of the championship that was created in 1932, and were runners-up in 1935–36. They also earned a USFSA Football Championship title in 1914, the French football top division before the creation of the French Division 1, and went to the Coupe de France final in 1939. Their neighbours, SC Fives, ranked second in 1933–34. They also went to the Coupe de France final, being defeated by Girondins AS Port in 1941. Weakened by the war, the two clubs decided to merge in the autumn of 1944, on 23 September, giving birth to Stade Lillois, renamed Lille Olympique Sporting Club a few weeks later. On 25 November 1944, the club is officially registered under its new name.

For its very first season, the newborn club reached the 1945 Coupe de France final, with a squad composed of the best players of both merging teams, who are mostly natives of the Nord department. Next season, Lille won the double, beating Red Star in the 1946 Coupe de France Final and finishing at the first place of French Division 1 ahead of Saint-Étienne and Roubaix-Tourcoing. In 1947, Lille finished in the fourth place but came back to the Coupe de France final and retained the trophy, defeating Strasbourg. The club won the cup again in 1948 beating main rivals Lens, its third in a row, and were runners-up of the league the same year, behind Marseille that became the champions after a strong 1947–48 season finishing. They were also runners-up in 1948–49, 1949–50 and 1950–51. On 24 June 1951, an exhausted Lille reached the Latin Cup final and lost against Gre-No-Li's AC Milan after having played 250 minutes in the span of two days.

On 31 May 1953, they got back to winning and earned their fourth Coupe de France trophy in a 2–1 final win against FC Nancy, before 60,000 spectators. The club then won its second domestic title in 1953–54, having only conceded 22 goals within 34 games. After this season, Lille is praised for its defensive proficiency and acquired a reputation as a rock-solid defense. A year later, Les Dogues earned their fifth Coupe de France in a 5-2 win against Bordeaux in the final. This period of glory and hegemony, occurring after the war and the German occupation of France, has led to one of the club's nicknames: La Machine de Guerre (French for "The War Machine"). Within its first decade of existence, the club gathered the vast majority of its major trophies, winning two league titles and reaching the second place for four consecutive seasons. Lille, known as the best French club in the post-war period, accumulated five Coupe de France wins in seven finals, including five successive finals and winning the trophy three times in a row, one of the best performances in the history of the tournament.

Decline and several spells in lower levels (1955–1978)

The 1955–56 season happened to be highly complicated. The club suffered from internal conflicts, Louis Henno was contested and certain players refused to play some matches. In the field, the Northmen were way too irregular and crumbly in defense, and finished in 16th place. Lille were relegated for the first time in their history in 1956. This relegation is accompanied by aggravating financial consequences. Best players' departure is necessary to cover debts which are becoming substantial. Failing to rebuild a top team due to the increasingly poor financial situation, the club began a series of promotions and relegations. Promoted in 1957 by beating Rennes, Lille initially ended up to an unexpected 6th place. The club then finished in eighteenth place the following season; being relegated a second time. After a few years spent in Division 2, the club became a mid-table side in the late 1960s. From 1964 to 1968, the club managed somehow to avoid relegation to the lower level. After a long drought, the worst occurred when Lille abandoned its professional status on 23 June 1969, lacking facilities and resources.

A few seasons spent in amateur leagues later, Lille recreated its professional team by entering the second division in 1970, finished at the top of the division at the end of the season. The club began a new series of promotions and relegations in the 1970s. During this decade, the club's accounts were largely in deficit. In order to cover debts, a support committee was founded and friendly matches were organized to raise funds. Famous clubs like Marseille or Feyenoord as well as nearby Belgian teams like Anderlecht and Standard Liège agreed to play against Lille to help the northern team. However, these ticket revenues only temporarily improve the club's financial situation but the Lille city council was again forced to help and intervene. At the lower level, Lille missed out on promotion in 1973 by one point but were crowned Division 2 champions the following year. After finishing twice in 13th place, during the 1974–75 and 1975–76 seasons, the club was once again relegated in 1977.

Reconstruction and reorganization (1978–2000)

After years of back and forth, Lille finally returned to the top tier of French football at the end of the 1977–78 season. Until 1997, the club remained in the first division, becoming a perennial member of the Division 1. In the 1978–79, the Mastiffs had a good run and ended at 6th place, nearly qualifying for European competitions while being promoted. The following year, in July 1980, Lille was the first French club to opt for the status of a mixed economy company (SAEMS), of which the city of Lille became the majority shareholder and turned the club into a public-controlled enterprise. The new financial sustainability allows the club's sporting stabilization in the elite division. LOSC then achieved some success stories in the decade, reaching the Coupe de France semi-finals in 1983 and 1985.

However, presidents Jacques Amyot, Roger Deschodt and Jacques Dewailly all struggled to compete with the top teams in the country and saw Lille staying in the familiar surroundings of mid-table. In 1991, Lille then-coached by Jacques Santini finished in sixth place, just two points from the European places; this is the club's only appearance in the league table top half in the 1990s. After financial problems, Bernard Lecomte took over as president of the club in 1994 and saved it from administrative relegation the following year by negotiating with the governing bodies. During this period of austerity where the National Football League prohibited the club from recruiting, LOSC had to part ways with its star players, such as Antoine Sibierski or Miladin Bečanović, and chose to develop its youth academy. Yet another economic crisis brought the club to the brink of bankruptcy and led to relegation to the second division in 1997.

While being in Division 2, the club was privatised and purchased in 1999 by Luc Dayan and Francis Graille. The team then trained by Bosnian coach Vahid Halilhodžić reconnected with success. Lille quickly recovered as Lille were head and shoulders over the other clubs during the 1999–2000 Division 2 season, the club dominated the championship thanks to excellent defense and finished champion with sixteen points ahead of its runner-up, being promoted back to the top.

Back to the top and new double (2000–2017)

In just its first season back in the top flight 2000–01 French Division 1, Lille qualified for Europe for the first time in the club's history, booking its place in the 2001–02 Champions League. On the back of the club's new status, Lille entered into a decisive new era under the guidance of chairman and chief executive officer Michel Seydoux and coach Claude Puel. The club left the historical Stade Grimonprez-Jooris to join the Stadium Lille Métropole and became a regular on the European scene. Amongst its most emphatic results was the 1–0 victory over Manchester United at the Stade de France in 2005, the 2–0 triumph over Milan in San Siro in 2006 and the 1–0 home win over Liverpool in 2010.

In the 2010s, Lille knew a steady development on and off the pitch, and has established itself as one of the most important clubs in French Ligue 1. First, the inauguration of the vast and modern Domaine de Luchin training complex in 2007 brings the club to a new era, the center being one of the largest in France. Roughly at the same time, the construction of the 50,000-capacity Grand Stade Lille Métropole (renamed later Stade Pierre-Mauroy), which opened in 2012, began on 29 March 2010 and will give the club the fourth-largest football stadium in France. Successive strong results and a sporting progression under head coach Rudi Garcia took the club back to the top of the French league. Fifty-six years after the club's last trophy, 2010–11 first team, led by home-grown players Yohan Cabaye, Mathieu Debuchy and Eden Hazard, won the club's second double after finishing at the 2010–11 Ligue 1 top spot and defeating Paris Saint-Germain in the 2011 Coupe de France final.

In the 2011–12 and 2012–13 Ligue 1 seasons, Lille confirmed its place belong top French football teams, finishing successively at the second and sixth places and qualifying for the 2012–13 Champions League. In 2013, Garcia left to join Roma, while former Montpellier coach René Girard was appointed as new manager. Under Girard, Lille finished at the third place in 2013–14, behind Zlatan Ibrahimović's Paris Saint-Germain and James Rodríguez's Monaco. After two years in charge of the club and a deceiving eight seed at the end of the 2014–15 Ligue 1 season, Girard left the club by mutual consent.

In May 2015, the Ivory Coast national team head coach Hervé Renard was appointed as the new manager. On 11 November 2015, Renard was terminated as manager and was replaced by Frederic Antonetti. On 23 November 2016, a year after being appointed, Lille terminated Antonetti's contract with the club lying second last in the table.

Campos and Galtier era: sustained success (2017–2021)

In early 2017, Lille appointed Luis Campos as sporting director and head of recruitment. A short time afterwards, the club announced the arrival of Argentine famous manager Marcelo Bielsa. In November 2017, Bielsa was suspended by Lille following an unauthorized trip to Chile with the club lying second from bottom on the table again and only managing 3 wins from the first 14 games of the season. On 23 December 2017, Bielsa was terminated by Lille and replaced with former Saint-Etienne manager Christophe Galtier. In a difficult 2017–18 season, Lille managed to avoid relegation to Ligue 2 by defeating Toulouse 3–2 in the second last game of the campaign.

Lille's following season is completely different. After the arrivals of veterans José Fonte and Loïc Rémy, Turkish right-back Zeki Çelik and forwards Jonathan Bamba, Jonathan Ikoné and Rafael Leão, the team proceeded to reel off a string of victories, losing only five games in the first part of the 2018–19 Ligue 1 season. On 14 April 2019, before a record attendance of 49,712 spectators, they defeated Paris Saint-Germain in a historic and storming 5–1 home win with goals from Nicolas Pépé, Jonathan Bamba, Gabriel and team captain José Fonte. At the end of the season, Lille secured the second place to qualify for the 2019–20 UEFA Champions League group stage; they returned to the competition after a seven-year absence. On 1 August 2019, club's season-top scorer Nicolas Pépé is sold to Premier League side Arsenal in a club-record fee of €80 million (£72 million). Lille announced the recruitment of Victor Osimhen and Tiago Djaló on the same day, after the signings of Timothy Weah, Reinildo Mandava and Benjamin André a few weeks earlier. The club then announced the arrivals of Yusuf Yazıcı and Renato Sanches to strengthen the midfield. In early March 2020, the Northmen were in 4th place with 49 points after 28 rounds. However, the Ligue 1 season ended abruptly as the LFP first suspended domestic leagues indefinitely following the outbreak of COVID-19 in France on 13 March, and then definitely cancelled French football competitions a month and a half later.

In the 2020 summer transfer window, Lille chose to sign young talents Sven Botman and Jonathan David as well as veteran Burak Yılmaz. At the end of the 2020–21 season first half, Lille had only lost two games and was well installed in the top league rankings, having defeated Derby du Nord rivals Lens in a 4–0 home win on 18 October 2020. The Mastiffs started the second part of the season with a six-game winning streak and lost only once until the end. On 3 April 2021, Lille won at Paris with a Jonathan David goal and took over sole possession of first place in the league. Three weeks later, Lille came back from two goals down to beat Lyon at Groupama Stadium as Burak Yılmaz scored twice including a 27-yard free kick in a breathtaking 3–2 away win. Lille then defeated local rivals once again, scoring three goals at Lens and prevailing in the season with an aggregate score of 7–0. On 23 May, Lille sealed the Ligue 1 title with a 2-1 victory at Angers after a dramatic Ligue 1 final round and won its fourth Ligue 1 title under the guidance of manager Christophe Galtier. At the end of the season, goalkeeper Mike Maignan finished the season with 21 clean sheets, one short of the league season all-time record. Competing also in the 2020–21 UEFA Europa League, they defeated AC Milan at San Siro, on 5 November 2020, in a big 3–0 away win with a hat-trick from Yusuf Yazıcı, but lost to Ajax in round of 32.

New cycle and Fonseca's arrival (2021–present)

In the 2021–22 season, Lille won its very first Trophée des Champions, defeating Paris Saint-Germain with a Xeka goal at Bloomfield Stadium in Tel Aviv, Israel on 1 August 2021. The Northmen then reached UEFA Champions League round of 16 and are defeated by Chelsea, after qualifying from the group stage against Salzburg, Sevilla and Wolfsburg. According to an analysis report published at the end of the Ligue 1 season, Lille is the fourth best French club in Ligue 1, in the 21st century, behind Paris Saint-Germain, Lyon and Marseille.

On 29 June 2022, the club appointed Paulo Fonseca as new head coach of the first-team. The 2022–23 season started very well for the Northmen as they defeated Auxerre, on 7 August, in a 4–1 home win. On 9 October, they defeated close rivals Lens in a 1–0 home win. Being one of the best offensive teams in the league, Fonseca's Lille is praised for its stylish, slick passing game and its attacking system. Since the beginning of the season, Lille have played in an open, offensive 4–2–3–1 formation with Benjamin André, André Gomes or Angel Gomes playing as central midfielders behind playmaker Rémy Cabella and lone striker Jonathan David. Following 4–3 home win over Monaco on 23 October, only Lyon and Paris Saint-Germain have had more possession in France in the 2022–23 Ligue 1 season.
