Arsenal 2003-04 unbeaten title-winning team is the first team to win the Premier League title having not lost a single game. And this great achievement has earned the nickname "The Invincibles". Today, a more than a decade from the 2003-04 season, Arsenal's current, or ex players may not care to remember the inbetween seasons, but they will always be able to look back with satisfaction on their record-breaking 49 game unbeaten run.

As they previously won the FA Cup in the season 2002-03, Arsenal continued their success, writing a record of 49 consecutive league games unbeaten from May 2003 to October 2004, and winning the Premier League title in 2003-04. But, Robert Pires' goal against Villa turned out to be the last of the run, as Manchester United stopped Wenger's 'Invincibles' in their tracks at Old Trafford, beating them 2-0. However, no other English club has gone undefeated for so many league games since the Football League began in 1888. Only Mourinho's Chelsea came close in 2005, but fell nine games short. In eight of Wenger's first nine seasons at the club, Arsenal finished in either first or second place in the league, and was part of the so-called "Big Four", along with Liverpool, Chelsea, and Manchester United in the mid-2000s, the clubs which dominated the first four spots which lead to the Champions League. Having always been knocked out in the quarter-finals previously, in the season 2005-06 Arsenal became the first club from London in the Champions League history to reach the final, in which after Lehmann was sent off, despite their lead, they lost 2–1 to Barcelona. In the same year, after Henry scored the penalty and kissed the turf in the very last match of the season against Wigan, beating them 4-2, they said goodbye to Highbury in style, after 93 years. In July, Arsenal moved into the Emirates Stadium. Unfortunately, since the Invincible season, they still haven't won the Premier League title, and in spite of reaching the League Cup finals in 2007 and 2011, and losing both of them, the first major trophy they won after 2005 FA Cup was the FA Cup in 2014 against Hull City. This win qualified them for the 2014 FA Community Shield, which they played against Manchester City, and won. Again, they became FA Cup finalists for the second year in a row, and by beating Aston Villa, they became the most successful club in the tournament's history with 12 titles. In August 2015, they won their 14th Community Shield title defeating Chelsea, and then, by defeating their London rivals again in the 2017 FA Cup final, they won the cup for 13th time and are still holding the record for most successful club. On the other hand, in spite of winning this trophy, Arsenal finished 5th in the Premier League, not qualifying for the Champions League, which is the first time since Wenger has arrived.

In brief, despite all the ups and downs throughout these years in the club, and the dissatisfaction the fans show lately through 'Wenger Out' paroles, the Frenchman has already written himself into Arsenal's history as the first manager of the club to collect three league championships. Arsenal's Invincibles season is never likely to happen again. But how unlikely? We shall just wait and see. In the meantime, just sing: 'Forty-nine, 49 undefeated, 49, 49, I say, 49, 49 undefeated, playing football the Arsenal way.', and remind yourself of the glorious past.
