Arsenal started their incredible 49-game unbeaten run in the Premier League at home to Southampton 17 years ago to the day.
Arsene Wenger's side went through the entire 2003-04 league season unbeaten, and the run lasted until 24 October 2004, when they suffered a 2-0 defeat away to Manchester United.
Liverpool had threatened to go through the current Premier League campaign unbeaten before losing to Watford, meaning that Arsenal's 'Invincibles' record will stand alone for at least another season.
As mentioned, Southampton were the first side that the Gunners overcame in May 2003, but how many of the other 48 teams can you name?
