Question: How many divisions did the league where Arsenal won in 2003-2004 season start out with at this time?

full_context: Document 1: Arsenal F.C.: Arsenal finished in either first or second place in the league in eight of Wenger's first eleven seasons at the club, although on no occasion were they able to retain the title. As of July 2013, they were one of only five teams, the others being Manchester United, Blackburn Rovers, Chelsea, and Manchester City, to have won the Premier League since its formation in 1992. Arsenal had never progressed beyond the quarter-finals of the Champions League until 2005–06; in that season they became the first club from London in the competition's fifty-year history to reach the final, in which they were beaten 2–1 by Barcelona. In July 2006, they moved into the Emirates Stadium, after 93 years at Highbury.
Document 2: Arsène Wenger: Arsène Charles Ernest Wenger  (French pronunciation: ​[aʁsɛn vɛŋɡɛʁ]; born 22 October 1949) is a French football manager and former player. He was the manager of Arsenal from 1996 to 2018, where he was the longest-serving and most successful in the club's history. His contribution to English football through changes to scouting, players' training and diet regimens revitalised Arsenal and aided the globalisation of the sport in the 21st century.
Document 3: Premier League: At the close of the 1991 season, a proposal was tabled for the establishment of a new league that would bring more money into the game overall. The Founder Members Agreement, signed on 17 July 1991 by the game's top-flight clubs, established the basic principles for setting up the FA Premier League. The newly formed top division would have commercial independence from The Football Association and the Football League, giving the FA Premier League licence to negotiate its own broadcast and sponsorship agreements. The argument given at the time was that the extra income would allow English clubs to compete with teams across Europe.

Document 5: Arsenal F.C.: The club's success in the late 1990s and first decade of the 21st century owed a great deal to the 1996 appointment of Arsène Wenger as manager. Wenger brought new tactics, a new training regime and several foreign players who complemented the existing English talent. Arsenal won a second League and Cup double in 1997–98 and a third in 2001–02. In addition, the club reached the final of the 1999–2000 UEFA Cup (losing on penalties to Galatasaray), were victorious in the 2003 and 2005 FA Cups, and won the Premier League in 2003–04 without losing a single match, an achievement which earned the side the nickname "The Invincibles". The feat came within a run of 49 league matches unbeaten from 7 May 2003 to 24 October 2004, a national record.
Document 6: Premier League: The Premier League is an English professional league for men's association football clubs. At the top of the English football league system, it is the country's primary football competition. Contested by 20 clubs, it operates on a system of promotion and relegation with the English Football League (EFL; known as ``The Football League ''before 2016 -- 17). Welsh clubs that compete in the English football league system can also qualify.

Document 8: Premier League: In 1992, the First Division clubs resigned from the Football League en masse and on 27 May 1992 the FA Premier League was formed as a limited company working out of an office at the Football Association's then headquarters in Lancaster Gate. This meant a break-up of the 104-year-old Football League that had operated until then with four divisions; the Premier League would operate with a single division and the Football League with three. There was no change in competition format; the same number of teams competed in the top flight, and promotion and relegation between the Premier League and the new First Division remained the same as the old First and Second Divisions with three teams relegated from the league and three promoted.
Document 9: History of Arsenal F.C. (1966–present): For the following season, Arsenal gradually progressed upon their league form, eventually becoming runners - up in 2016. In order to capture that ever - elusive Premier League title for the first time in 12 years, the club spent heavily in the transfer market in the summer of 2016, spending over £80 million on four first - team acquisitions, namely capturing Shkodran Mustafi and Granit Xhaka, who operate as a central defender and central midfielder, respectively. Both positions were long deemed problem positions in the team, with the hope Arsenal could push on and win the league after signing the pair. However, poor league form saw Arsenal competing heavily for the final UEFA Champions League space, having taken a race with Liverpool and Manchester City to the final day of the season. Despite winning 3 - 1 against Everton, results elsewhere meant they only finished fifth, missing out on a Champions League spot for the first time in two decades, and the first ever under Wenger. However, Arsenal won the FA Cup Final 2 - 1 against Chelsea, making it their third win in four seasons, and made them the most successful club in the history of the competition.
Document 10: Premier League: The league held its first season in 1992–93 and was originally composed of 22 clubs. The first ever Premier League goal was scored by Brian Deane of Sheffield United in a 2–1 win against Manchester United. The 22 inaugural members of the new Premier League were Arsenal, Aston Villa, Blackburn Rovers, Chelsea, Coventry City, Crystal Palace, Everton, Ipswich Town, Leeds United, Liverpool, Manchester City, Manchester United, Middlesbrough, Norwich City, Nottingham Forest, Oldham Athletic, Queens Park Rangers, Sheffield United, Sheffield Wednesday, Southampton, Tottenham Hotspur, and Wimbledon. Luton Town, Notts County and West Ham United were the three teams relegated from the old first division at the end of the 1991–92 season, and did not take part in the inaugural Premier League season.
Document 11: Premier League: There has been an increasing gulf between the Premier League and the Football League. Since its split with the Football League, many established clubs in the Premier League have managed to distance themselves from their counterparts in lower leagues. Owing in large part to the disparity in revenue from television rights between the leagues, many newly promoted teams have found it difficult to avoid relegation in their first season in the Premier League. In every season except 2001–02 and 2011–12, at least one Premier League newcomer has been relegated back to the Football League. In 1997–98 all three promoted clubs were relegated at the end of the season.
Document 12: Arsenal F.C.: They hold the highest number of FA Cup trophies, with 13. The club is one of only six clubs to have won the FA Cup twice in succession, in 2002 and 2003, and 2014 and 2015. Arsenal have achieved three League and FA Cup ``Doubles ''(in 1971, 1998 and 2002), a feat only previously achieved by Manchester United (in 1994, 1996 and 1999). They were the first side in English football to complete the FA Cup and League Cup double, in 1993. Arsenal were also the first London club to reach the final of the UEFA Champions League, in 2006, losing the final 2 -- 1 to Barcelona.
Document 13: List of football clubs in England by competitive honours won: England's first football competition, the FA Cup, began in the 1871 -- 72 season, making it the oldest football competition in the world. Arsenal hold the record number of wins, with 13. League football began in the next decade with the founding of The Football League in 1888 -- 89. The name First Division was adopted in 1892, when The Football League gained a second division. The First Division remained the highest division of the English football league system until 1992, when the Premier League was founded. Manchester United have won the most top division titles, with 20. The English equivalent of the super cup began in 1898 with the inauguration of the Sheriff of London Charity Shield, pitting the best professional and amateur sides of the year against each other. The trophy would develop into the FA Charity Shield in 1908, which was later renamed the FA Community Shield in 2002. Manchester United hold the record in the competition with 21 wins. The Football League created its own knockout competition in 1960, the League Cup. The Anglo - Italian League Cup was created in 1969 to match English cup winners against the winners of the Coppa Italia, and was permanently disbanded in 1976. In 1985, the Full Members Cup and Football League Super Cup were created as substitutes for UEFA competitions after UEFA responded to the Heysel Stadium disaster by banning English clubs. They finished in 1986 and 1992 respectively. The Football League Centenary Trophy marked The Football League's 100th birthday, in the 1988 -- 89 season.
Document 14: Arsenal F.C.: The return of former player George Graham as manager in 1986 brought a third period of glory. Arsenal won the League Cup in 1987, Graham's first season in charge. This was followed by a League title win in 1988–89, won with a last-minute goal in the final game of the season against fellow title challengers Liverpool. Graham's Arsenal won another title in 1990–91, losing only one match, won the FA Cup and League Cup double in 1993, and a second European trophy, the European Cup Winners' Cup, in 1994. Graham's reputation was tarnished when he was found to have taken kickbacks from agent Rune Hauge for signing certain players, and he was dismissed in 1995. His replacement, Bruce Rioch, lasted for only one season, leaving the club after a dispute with the board of directors.
Document 15: Arsenal F.C.: Arsenal Football Club is a professional football club based in Islington, London, England, that plays in the Premier League, the top flight of English football.
