Arsenal stay on the coattails of leaders Leicester following a routine win over an Everton side who hardly threatened the visitors.
Danny Welbeck opened the scoring for the Gunners in the seventh minute, rounding off a fine team move as he got on the end of Alexis Sanchez’s through ball before rounding Joel Robles and rolling the ball home.
In a frantic first half it was the visitors who created the better chances, Alex Iwobi shooting straight at the goalkeeper moments after Welbeck’s opener.
Sanchez then went down in the box under the challenge of Muhamed Besic but referee Mark Clattenburg was not interested.
Arsenal made their dominance count three minutes before half-time when Iwobi netted his first goal for the Gunners, breaking away from the Everton defence and sliding the ball though the legs of Robles.
Iwobi, who was making his first league start, had a chance to grab his second professional goal soon after his first but fired wide when unmarked in the box.
Phil Jagielka had the clearest sight of goal for Everton in the second period but could not hit the target with his header.
As Roberto Martinez’s men huffed and puffed they nearly conceded a third, substitute Olivier Giroud netting a header only for the referee to rule it out for a push.
The win keeps Arsenal in the title race but it is now three defeats on the bounce at home in the league for Everton who remain in the bottom half of the table.
