Arsenal proved their season still has signs of life after twice battling back to earn a 2-2 draw with their Premier League top-four rivals Manchester City.
Leroy Sane put the visitors ahead inside five minutes and Sergio Aguero restored the lead for Pep Guardiola's men just 131 seconds after Theo Walcott had levelled.
Shkodran Mustafi headed Arsenal back on terms once more with just his second goal for the Gunners, who remain sixth in the table as a result - seven points adrift of City in fourth.
If you were too engrossed in the action to miss the little things, do not worry. Here are five things you need to know:
Arsenal fans fighting amongst themselves
It is a fractious time at the Emirates currently and it appears some fans have let their frustrations get the better of them.
Supporters in the home stands were caught brawling on bystanders' video in scenes reminiscent of Millwall's fans FA Cup semi-final shame from 2013, albeit on a far smaller scale. The fight was broken up and the perpetrators ejected from the stadium. There is no indication over what caused the fight.
Wenger's water bottle the innocent victim
Arsene Wenger has cut an increasingly forlorn figure in the Emirates dug out of late and frustration reared its head when Arsenal conceded the second.
Visibly trying to control his breathing after Mesut Ozil gives the ball away Wenger can handle it no longer when Aguero makes them pay. Steve Bould looks almost as fed up.
Just 90 seconds after equalising, slack defending allowed Sergio Aguero to put City back in front and Wenger let his water bottle have it.
Jesus is a right back and he confuses Twitter graphic folk
Full back converts are all the rage in the Premier League these days. Victor Moses is perhaps the best example this season but Antonio Valencia has long been the model for moving wingers backwards.
After employing Fernandinho at full-back in recent weeks, Pep Guardiola recalled the rarely-seen Jesus Navas on the right side of defence and stationed the Brazilian in his more familiar position in front of the back four.
It was a selection that took City social media team by surprise. They put their line-up graphic which showed a a midfield four of Navas, David Silva, Kevin De Bruyne and Sane.
Navas might have working on the defensive side of the game on the training ground but his tackling is still a work in progress. He was lucky to stay on the pitch for his knee-high lunge at Nacho Monreal.
A true blue fan not afraid to show his colours
Some football fans are more prepared to show their true colours than others. This City supporter certainly has no problem in that regard.
In head to toe sky blue, with sunglasses and a lunchbox to match, he stuck out like a sore thumb outside the Emirates as a walking advert for the visitors' club shop.
With that much polyester on just don't let him stand near any open flames.
Lyle to me once, shame on you
The bafflingly popular Arsenal Fan TV pulled a 'hilarious' prank on their viewers for April Fools Day, with presenter DT announcing that main man Robbie Lyle had earned a big-money move to Borussia Dortmund.
For the surprisingly large number of viewers that fell for the joke they must have been relieved to see Lyle and his familiar red Popsicle microphone bothering people outside the ground.
