Arsenal went into the match knowing a win would move them back up to third and put them in a good position in the race to finish in the top four.
But Everton dominated from the outset and were rewarded for their bright start when Arsenal failed to deal with a long throw from Lucas Digne and Phil Jagielka poked home in the tenth minute.
The Toffees then had several chances to score a second goal but failed to take their chances in the second half while Arsenal had just two shots on target in the entire match.
Arsenal face four more away league games this season and must dramatically improve if they want to qualify for the Champions League.
ARSENAL PLAYER RATINGS VS EVERTON
Leno: Everton had ample opportunities to score but rarely threatened the German keeper. Little he could do with Jagielka’s goal – 5
Maitland-Niles: A thrown in which went straight out of play summed up his performance. Totally bullied by Digne and he was unable to deal with Bernard – 4
Sokratis: Booked early on which means he will miss the next two league games. Involved in a physical battle with Dominic Calvert-Lewin all match – 5
Mesut Ozil was poor for Arsenal
Arsenal’s Mohamed Elneny was hauled off at half-time
Mustafi: A major liability in the Arsenal defence. Slow with the ball at his feet, soft in challenges and not of the standard required – 3
Monreal: The Spaniard struggled all game with the pressing from Everton. Richarlison attacked him at will – 4
Elneny: Brought into the team due to a Granit Xhaka injury and Aaron Ramsey on the bench. But the Egyptian was woeful in midfield – 2
Guendouzi: Another Arsenal player who was shown an early yellow card and he was a shadow of the player he has been this season – 4
Alexandre Lacazette offered little for Arsenal
Kolasinac: Usually the big Bosnian is an effective attacking source for Arsenal but he offered nothing before being taken off at half-time – 4
Mkhitaryan: On the fringes of the match the whole game. Some nice touches but rarely producing anything worthwhile – 5
Ozil: His first away start of 2019 and it was easy to see why. Dropped far too deep to get the ball, couldn’t handle Everton’s intensity and ultimately taken off with a whimper – 3
Lacazette: Should have had a penalty in the first half. But apart from that he did nothing of note – 4
