Chelsea and Arsenal played out a thrilling 2-2 draw at the Emirates Stadium on Monday night.
The Gunners took the lead through Jack Wilshere before Eden Hazard equalised for the visitors from the spot.
Marcos Alonso appeared to have won the game for the Blues but Hector Bellerin popped up with a late goal to secure an important draw for Arsene Wenger's side.
Chelsea coach Antonio Conte admitted there was plenty of "disappointment" regarding the result but appreciated that it was a great spectacle for fans.
“I think this game was an exciting game for people watching, less for us," said Conte to reporters.
"When you’re winning 2-1 with two minutes to go you have to win the game, especially against a great team like Arsenal.
"The final result is a good result – a draw against Arsenal at the Emirates Stadium is a good result – but at the end of the game there’s a lot of disappointment. We created enough chances to win the game."
Chelsea lie third in the Premier League table, seven points ahead of sixth placed Arsenal.
Chelsea fan celebrating in Arsenal end goes viral
As an away supporter in the Premier League, the general etiquette is not to celebrate your team's goals if you are sitting with the home fans.
However, the Emirates is certainly not renowned for it's fiery atmosphere and - despite it being a London derby - one Chelsea fan took advantage of that.
Filming Hazard's penalty amongst Gooners, one brazen Blue supporter chose to celebrate noisily and managed to completely get away with it.
Apart from a few dirty looks, the Arsenal fans around him were bizarrely placid and were quite content to ignore his whooping and cheering.
What fans were saying in the comments
The video went viral on Twitter and users on social media were not impressed by the Arsenal fans reaction in the stands.
Arsenal have won just two of their last eight league games but visit Nottingham Forest in the FA Cup on Sunday afternoon.
