In 2003/04, Arsenal achieved the seemingly impossible and went an entire Premier League campaign unbeaten.Arsene Wenger's star-studded side won 26 games, drew 12 and lost zero on their way to a third title in the space of six years.The team aptly nicknamed 'The Invincibles' had it all, with the likes of Sol Campbell, Patrick Vieira, Robert Pires, Dennis Bergkamp and Thierry Henry simply too good for the rest of the division.The season after their historic feat, Arsenal went on to break another English football record by extending the unbeaten run to 49 games.But their dreams of reaching the magic 50 were shattered by none other than Manchester United.Sir Alex Ferguson's side won 2-0 at Old Trafford in October 2004 thanks to second half goals from Ruud van Nistelrooy and Wayne Rooney.
However, it's a fixture that remains one of the most controversial in Premier League history.On the pitch, Arsenal had every right to feel cheated. Some of the incidents included Van Nistelrooy getting away with a shocking challenge on Ashley Cole, Rio Ferdinand somehow escaping a red card for a last-man tackle on Freddie Ljungberg and Rooney blatantly diving to win a penalty.Off the pitch, there was the infamous 'battle of the buffet' in the tunnel during where Arsenal's Cesc Fabregas hit Fergie with a slice of pizza.

We lost count of how many times the late Jose Antonio Reyes was fouled by United players.
The hosts got away with a lot and if VAR had been in place all those years ago, Fergie's side would have possibly been down to nine men and not been handed the chance to score from the spot.
In April 2019, Wenger touched on the events that unfolded on that rainy afternoon at Old Trafford in 2004.
“We lost our invincibility against Manchester United in a match in which the referees were partly responsible," he said. "It was not deserved. If I die, I am going to ask God where the referees are before choosing between heaven and hell."
Wenger at least managed to get revenge on United at the end of the 2004/05 season.
Arsenal beat their arch nemesis on penalties in the final of the FA Cup, although that was to be the club's last trophy win for nine long years.
