April 25, 2004 is one of the most memorable days in Arsenal's history.
Arsene Wenger's side went into their game against Tottenham Hotspur at White Hart Lane knowing a point would see them clinch the Premier League title.
And they got off to a great start when Patrick Vieira put them in front with a superb team goal after just three minutes.
And the Gunners were 2-0 up at the break, with Robert Pires netting their second in the 33rd minute.
Tottenham fought back, though.
Jamie Redknapp fired past Jens Lehmann in the 63rd minute to reduce the deficit to one.
And Spurs actually restored parity in stoppage time when Robbie Keane converted from the penalty spot.
That goal gave Spurs hope of a dramatic comeback and set up a nervy finish for Arsenal.
But Wenger's side held on to grab the point they needed and clinch their third Premier League title.
You can watch highlights from the game, which was 16 years ago today, below:
Despite letting the two-goal lead slip, Arsenal's players were understandably jubilant at the final whistle as they celebrated in front of the travelling away fans.
Tottenham fans, despite grabbing a vital point in their fight against relegation, raced home to avoid watching their rivals celebrate the title.
That was actually the second time that Arsenal have won the league title at the home of their fierce rivals.
They also did so back in 1971 in another drama filled game.
Ray Kennedy headed home the winner for Bertie Mee's side in the 88th minute.
Arsenal had even more reason to celebrate a few weeks later when they went unbeaten for their remaining games.
That meant they did not taste defeat in their 38 Premier League games, becoming the first ever invincible side.
The 2003/04 season really was an incredible campaign for Arsenal and it was Wenger who made that all possible.
