Arsenal 4-2 Tottenham - what a game.
It was fast and furious at the Emirates stadium as Pierre-Emerick Aubameyang opened the scoring inside 10 minutes with a penalty after Jan Vertonghen handled the ball.
Eric Dier then headed home from Christian Eriksen's free-kick on the half hour mark before Harry Kane made it 2-1 Spurs from the penalty spot four minutes later.
Referee Mike Dean adjudged Rob Holding to have brought down Son Heung-min in the box with a sliding tackle, although replays showed there was very little contact.
Arsenal manager Unai Emery made two alterations at half-time - Aaron Ramsey and Alexandre Lacazette came on for Alex Iwobi and Henrikh Mkhitaryan - and they changed the game.
Ramsey provided the assist for Aubameyang to make it 2-2 in the 56th minute and then teed up Lacazette for Arsenal's third goal.
And with 13 minutes remaining of the game, summer signing Lucas Torreira broke through Spurs' defence and fired past Hugo Lloris to seal an important victory.
As always, the latest north London derby wasn't without controversy as Arsenal and Tottenham players brawled after Dier's goal and Son won a controversial penalty.
Holding took a big risk by lunging in but barely touched the South Korean, who went down as soon as he felt contact and made a meal of it.
Not that Holding will care. Arsenal produced a sensational comeback and are now back in the top four after leapfrogging their local rivals.
And now the young centre-back has rubbed it in even more by trolling Tottenham with a pretty hilarious tweet that's going viral.
In response to his own tweet from Saturday, Holding wrote: "Loading failed.... Your opponent left the match," with the laughing-crying and eyes emojis. Check it out.
Naturally, Arsenal fans are absolutely loving Holding's tweet and he deserves his moment in the spotlight after another mature performance.
