On 15th May 2004, Arsenal rounded up their historical campaign by beating Leicester City 2-1 to finish the 2003/2004 Premier League season unbeaten, according to the Official Club website.
Arsenal were on the verge of letting their unbeaten run slip right out of their grip when The Foxes took the lead in the 25th minute through a Paul Dickov header. The sensational and ever clinical Thierry Henry however converted from the spot to level the score after Ashley Cole was clumsily fouled in the box by Frank Sinclair right after the interval.
Captain and 1998 World Cup Winner with France, Patrick Vieira gave Arsenal the lead midway through the second and with that, Arsene Wenger’s boys never looked back.
The 49-game unbeaten run between May 2003 and October 2004, which can be found on Arsenal.com, broke Nottingham Forest’s previous record of 42 games unbeaten in the 1977/78 season.
The run ended in October 2004 when a controversial Ruud van Nistelrooy penalty inspired Manchester United to a 2-0 win at Old Trafford…
But what a run by the Gunners, still unmatched more than a decade later.
