Association de la Jeunesse Auxerroise (French pronunciation: ​[asɔsjɑsjɔ̃ də la ʒœnɛs osɛʁwaz]), commonly known as AJ Auxerre or simply Auxerre ([osɛʁ]), is a French football club based in the commune of Auxerre in Burgundy. The club was founded in 1905 and currently plays in Ligue 1, the first division of French football. Auxerre plays its home matches at the Stade l'Abbé-Deschamps on the banks of the Yonne River. The team is managed by Jean-Marc Furlan and captained by midfielder Birama Touré.

Auxerre was founded in 1905 and made its debut in the first division of French football in the 1980–81 season and remained a fixture in the league until the 2011–12 season. The club has won the Ligue 1 title once, in the 1995–96 season. Two years prior, Auxerre achieved its first major honour by winning the Coupe de France in 1994. The club has since added three more Coupe de France titles, which ties the club for fifth-best among teams who have won the trophy.

Auxerre has produced several notable players during its existence. The club has most notably served as a springboard for several prominent French football players such as Eric Cantona, Laurent Blanc, Stéphane Guivarc'h, Philippe Mexès, Basile Boli, and Djibril Cissé, among others, who all became French internationals, with Blanc playing on the teams that won the 1998 FIFA World Cup and UEFA Euro 2000. Guivarc'h, Bernard Diomède and Lionel Charbonnier were the three footballers from Auxerre who were world champions in 1998. From 1961 to 2005, the club was predominantly coached by Guy Roux. This included an uninterrupted period when Roux was in charge for 36 years between 1964 and 2000.

Paris Saint-Germain Football Club was founded in August 1970 after the merger of Paris Football Club and Stade Saint-Germain. PSG made an immediate impact, winning promotion to Division 1 and claiming the Division 2 title in their first season. Their momentum was soon checked, however, and the club split in 1972. Paris FC remained in the top flight, while PSG were administratively relegated to Division 3. Following back-to-back promotions, PSG quickly returned to the premier division in 1974 and moved into the Parc des Princes.

The club's first trophies arrived in the 1980s. Steered by players such as Safet Sušić, Luis Fernandez and Dominique Rocheteau, the Parisians claimed two consecutive French Cup titles in 1982 and 1983 followed by their maiden league championship in 1986, after which they went into decline. But a takeover by television giants Canal+ in 1991 revitalised PSG. Led by David Ginola, George Weah and Raí, the club won nine trophies and reached five consecutive European semi-finals during the 1990s. Most notably, Paris claimed a second league title in 1994 and its crowning glory, the UEFA Cup Winners' Cup in 1996 with legend Luis Fernandez now as coach.

At the start of the 21st century, the Red and Blues struggled to rescale the heights despite the magic of Ronaldinho and the goals of Pauleta. Five more trophies arrived in the form of three French Cups, one French League Cup and one UEFA Intertoto Cup, but the capital side became better known for lurching from one high-profile crisis to another. As a result, Canal+ sold the club to Colony Capital in 2006. The situation, however, only got worse and PSG spent the 2006–07 and 2007–08 campaigns staving off relegations.

The fortunes of Paris Saint-Germain changed dramatically when Qatar Sports Investments (QSI) purchased the club in 2011. Since then, Paris have spent heavily on the signings of world-class players such as Zlatan Ibrahimović, Thiago Silva, Edinson Cavani, Ángel Di María and, most notably, Neymar and Kylian Mbappé, the world's two most expensive transfers in football history. As a result, PSG have dominated French football, winning 27 trophies: seven league titles, six French Cups, six French League Cups and eight French Super Cups. They have also become a regular in the knockout stages of the Champions League, reaching the final for the first time ever in 2020.
