Arsenal won the north London derby bragging rights with a comeback 4-2 victory over Tottenham at the Emirates Stadium on Sunday night.
The hosts took the lead in the 10th minute via a Pierre-Emerick Aubameyang penalty after Jan Vertonghen raised an arm to clear the ball in penalty area.
But Spurs turned the game on its head in a five-minute spell on the half-hour mark as Eric Dier glanced a free kick inside the near post and Harry Kane drilled home a dubious penalty.
The Gunners levelled the score (2-2) 10 minutes after the break thanks to Aubameyang's second goal.
With the momentum swung, Arsenal got their noses in front in with 15 minutes to play when Alexandre Lacazette came off the bench to score and Lucas Torreira made it 4-2.
Meanwhile, Divock Origi scored the only goal with the last kick of the game as Liverpool beat Everton 1-0 in the Merseyside derby at Anfield.
