text: Lille Olympique Sporting Club (), commonly referred to as LOSC, LOSC Lille or simply Lille, is a French professional football club based in Lille, Hauts-de-France that competes in Ligue 1, the top division of French football. Lille has played its home matches since 2012 at the Stade Pierre-Mauroy. The 50,186-capacity retractable roof venue is the fourth-largest football stadium in France.
  Lille was founded as a result of a merger between Olympique Lillois and SC Fives in 1944. Both clubs were founding members of the French Division 1 and Olympique Lillois was the league's inaugural champions. The club's most successful period was the decade from 1946 to 1956, in the post-war period, when the team led by managers George Berry and André Cheuva won seven major trophies, including a League/Cup double in 1946, and was known as La Machine de Guerre (French for "The War Machine"). Having won another double in 2011, its fourth league title in 2021 as well as its first French super cup, Lille is the fourth best French club in the 21st century.
