FC Bayern Munich in the context of "Franz Beckenbauer"

The Double, in association football, is the achievement of winning a country's top tier division and its primary domestic cup competition in the same season. The lists in this article examine this definition of a double, while derivative sections examine much less frequent, continental instances. The Double can also mean beating a team both home and away in the same league season, a feat often noted as doing the double over a particular opponent.

The first club to achieve a double was Preston North End in 1889, winning the FA Cup and The Football League in the inaugural season of the league.

Gerd Müller (German pronunciation: [ˈɡɛʁt ˈmʏlɐ]; 3 November 1945 – 15 August 2021) was a German professional footballer. A prolific striker, especially in and around the six-yard box, he is widely regarded as one of the greatest goalscorers and players in the history of the sport. With success at club and international level, he is one of ten players to have won the FIFA World Cup, the UEFA Champions League and the Ballon d'Or.

At international level with West Germany, he scored 68 goals in 62 appearances, and at club level, in 15 years with Bayern Munich, in which he scored 365 goals in 427 Bundesliga matches, he became—and still is—record holder of that league. In 74 European club games he scored 65 goals. Averaging over a goal a game with West Germany, Müller was, as of 11 July 2021, 21st on the list of all time international goalscorers, despite having played fewer matches than every other player in the top 48. Among the top scorers, he has the third-highest goal-to-game ratio. He also had the highest ratio of 0.97 goals per game in the European Cup, scoring 34 goals in 35 matches.

Josef Dieter "Sepp" Maier (German pronunciation: [ˈjoːzɛf ˈdiːtɐ zɛp ˈmaɪɐ]; born 28 February 1944) is a German former professional footballer who played as a goalkeeper for Bayern Munich and the West Germany national team. Regarded as one of football's greatest goalkeepers, he was nicknamed "Die Katze von Anzing" ("the cat from Anzing") for his fast reflexes, agility, flexibility, speed, and consistency. With 709 matches played across seventeen seasons, he was Bayern's all-time record appearance holder, until he was surpassed by Thomas Müller in 2024.

In addition to his shot-stopping ability, Maier was also known for his ability to dominate his box, as well as his sense of humour and personality throughout his career, which made him a fan favourite. Regarding his playing style, he once quipped "a keeper should give off a sense of calm, and not fall asleep while doing so."

In top-level association football competitions, 26 players have scored 500 or more goals in both club and international football, according to research by the IFFHS, first published in 2007. Taking into account competitions of all levels, 82 players have reached the milestone, according to the RSSSF. FIFA, the international governing body of football, has never released a list detailing the highest goalscorers and does not keep official records. It is challenging for statisticians and media to agree on which goals should be counted, with debate over whether to include those scored in friendlies, regional competitions, and even matches taking place during wartime. Hungarian Imre Schlosser is generally recognised as the first to reach the 500-goal mark, doing so in 1927 shortly before his retirement. Nine players have accomplished the feat at a single club: Josef Bican (Slavia Prague), Jimmy Jones (Glenavon), Jimmy McGrory (Celtic), Joe Bambrick (Linfield), Lionel Messi (Barcelona), Gerd Müller (Bayern Munich), Pelé (Santos), Fernando Peyroteo (Sporting CP), and Uwe Seeler (Hamburg). Of these nine, Messi scored the most, with 672 goals between his debut in 2004 and his departure in 2021.

In 2020, FIFA recognised Josef Bican, an Austrian-Czech dual international who played between the 1930s and the 1950s, as the record scorer with an estimated 805 goals, although CNN, the BBC, France 24, and O Jogo all acknowledge that Bican's tally includes goals scored for reserve teams and in unofficial international matches. UEFA, the governing body for European football, ranks him as the leading all-time goalscorer in European top-flight leagues with 518 goals, narrowly ahead of Hungarian Ferenc Puskás. RSSSF credits Bican with 948 goals, a tally which includes goals scored in winter tournaments, as well as when selected to represent regional and city teams, and the Football Association of the Czech Republic claims a total of 821. Spanish newspapers Marca and Sport state that both Bican and Pelé scored 762 goals. Bican once walked out of a gala held in his honour by the IFFHS after the organisation had excluded war-time goals from his tally, although it later recognised the 229 goals he had scored during the period.

A treble in association football is achieved when a club team wins three trophies in a single season. A continental treble involves winning the club's top-level domestic league competition, main domestic cup competition, and main continental trophy. Although winning a second-tier continental trophy (e.g. Europa League) has also been described as a continental treble, it is not as widely accepted. A domestic treble involves winning three national competitions—including the league title, the primary cup competition, and one secondary competition, such as a league cup.

Competitions which consist of a single match or a two-leg match are not normally counted as part of a continental treble (e.g., the FA Community Shield, Supercopa de España, Supercoppa Italiana, Trophée des Champions, DFL-Supercup, UEFA Super Cup, Recopa Sudamericana, FIFA Club World Cup (2005–2023 editions), Intercontinental Cup and others).

The 2014–15 season was Futbol Club Barcelona's 116th in existence and the club's 84th consecutive season in the top flight of Spanish football. This was the first of the three seasons under head coach Luis Enrique.

The season was one of the most successful ones in the club's history, as Barcelona clinched its second continental treble after winning La Liga, the Copa del Rey and the UEFA Champions League. The league title was won in a closely fought title race with Real Madrid, while the Copa victory was achieved with a brilliant 3–1 victory over Athletic Bilbao at Camp Nou in the final. In the Champions League, Barcelona overcame Bayern Munich (3–0 home, 2–3 away) to set up the final against Juventus in Berlin, where Barça triumphed 3–1. Barcelona's success may be in large part attributed to their formidable attacking trio composed of Lionel Messi, Neymar, and summer signing Luis Suárez, who scored a record 122 goals in all competitions to become the trio with most goals in a single season in Spanish football history.

Mario Mandžukić (Croatian pronunciation: [mâːrio mǎndʒukitɕ]; born 21 May 1986) is a Croatian football coach and a former player who was most recently an assistant coach for the Croatia national team. As a player, he played as a forward and became known for his aggressiveness, defensive contribution, and aerial prowess.

Starting his career in 2004 at hometown club Marsonia, Mandžukić then moved to two Zagreb-based clubs: NK Zagreb in 2005 and Dinamo Zagreb in 2007. He was Croatian First League top goalscorer in the 2008–09 season. After joining VfL Wolfsburg in 2010, Mandžukić moved to fellow-Bundesliga side Bayern Munich in 2012. He helped Bayern win their first continental treble (Bundesliga, DFB-Pokal, Champions League) in his first season, and became the first Croatian to score in a Champions League final. After winning a domestic double the following season, he left Bayern for La Liga club Atlético Madrid in 2014, and a season later was signed by Juventus in the Serie A. Mandžukić won four league titles and three Coppa Italia titles with Juventus, and reached the 2017 Champions League final. He left Juventus in December 2019 for Qatari side Al-Duhail and returned Italy in January 2021, signing with AC Milan. He retired in September of the same year.

Ivan Perišić (Croatian pronunciation: [ǐʋan pěriʃitɕ]; born 2 February 1989) is a Croatian professional footballer who plays as a winger for Eredivisie club PSV and the Croatia national team. Usually deployed as a left winger, he has also featured as a left wing-back, right winger, and in the beginning of his career as an attacking midfielder or even second striker. Known for his ambipedality and versatility, he is widely considered one of the greatest Croatian players of all time, as well as one of the best players in his position, lauded by the likes of Luciano Spalletti, José Mourinho, Antonio Conte, Hansi Flick and other high profile managers.

A product of the Hajduk Split and Sochaux youth academies, Perišić made a name for himself while playing for Club Brugge, where he was the Belgian Pro League top goalscorer and was named Belgian Footballer of the Year for 2011. This earned him a transfer to Borussia Dortmund, with whom he won the 2011–12 Bundesliga, before signing with VfL Wolfsburg for €8 million in January 2013. He remained there for two and a half seasons, winning the 2015 DFB-Pokal final, before moving to Inter Milan for €16 million. In 2019, he joined Bayern Munich on loan, winning the treble. After returning to Inter Milan, he won the 2020–21 Serie A, the 2021 Supercoppa Italiana and the 2021–22 Coppa Italia.

The UEFA Champions League is a seasonal football competition established in 1955. Prior to the 1992–93 season, the tournament was named the European Cup. The UEFA Champions League is open to the league champions of all UEFA (Union of European Football Associations) member associations (except Liechtenstein, which has no league competition), as well as to the clubs finishing from second to fourth position in the strongest leagues. Originally, only the champions of their respective national league and the defending champions of the competition were allowed to participate. However, this was changed in 1997 to allow the runners-up of the stronger leagues to compete as well, and again in 1999 when third and fourth-placed teams of the said leagues also became eligible. In the Champions League era, the defending champions of the competition did not automatically qualify until the rules were changed in 2005 to allow title holders Liverpool to enter the competition.

Teams that have won the UEFA Champions League three consecutive times, or five times overall, receive a multiple-winner badge. Six teams have earned this privilege: Real Madrid, Ajax, Bayern Munich, AC Milan, Liverpool, and Barcelona. Until 2009, clubs that had earned that badge were allowed to keep the European Champion Clubs' Cup and a new one was commissioned; since 2009, the winning team each year has received a full-size replica of the trophy, while the original is retained by UEFA.
