Arsenal started the match not very well with couple of mistakes.
Because of Mustafi's mistake Everton took the lead in the 1st minute of the game.
Everton have scored right at the end of the half as well as at the beginning of it.
Ceballos conceded a free kick in the middle of the Arsenal half. Sigurdsson send it into the box, Luiz made a mess of his attempted clearance, and Calvert-Lewin was unmarked to send an acrobatic finish past Leno.
Kolasinac got injured and Saka came in. A few minutes later he assisted a great ball to Eddie Nketiah who netted the ball past Pickford.
Aubameyang scored Arsenal second goal in the 33rd minute. David Luiz carried the ball forward just inside the Arsenal half and passed right to Aubameyang who was running off the shoulder of Sidibe.
However, right before half time Richarlison equalized the score line after a terrible mistake by Leno.
Everton dominated for most of the second half but they couldn't quite find the finishing touches they needed to win.
Although, Leno made a terrible mistake in the first half that led to a goal, he made some excellent saves in the second half.
Aubameyang's goal just 22 seconds after the start of the second half eventually proves decisive.
This was a big win for the Gunners.
The result means Arsenal leapfrog Everton into ninth, seven points off the top four with 11 to play. Everton are a point further back in 11th.
