Everton 2 Arsenal 5: Koeman on the brink as hosts capitulate

Gueye robbed Granit Xhaka just outside the area and Rooney duly struck a sumptuous effort into the top-left corner from 25 yards.

But Arsenal's persistence finally paid off five minutes before the break - Monreal smashing a low shot beyond the goalkeeper after Xhaka's previous effort was parried.

Koeman injected a little more energy into his midfield by bringing Tom Davies on for Ashley Williams at half-time, but Arsenal remained the more purposeful going forward.

They completed the turnaround eight minutes after the break, with Sanchez clipping a delicate ball into the danger zone and Ozil was there to head past Pickford at the end of a swift break.

Things were made even more difficult for Everton when Gueye picked up a second booking for a rash tackle on Xhaka 22 minutes from the end, with the Gunners taking advantage soon after as Lacazette swept home from 12 yards.

Ramsey opened up a three-goal lead in the 90th minute with a cool finish following an incisive pass from substitute Jack Wilshere.

A defensive mix-up between Monreal and Petr Cech allowed Niasse to pull one back in calamitous circumstances a few moments later, but Sanchez ensured Arsenal had the last laugh, finding the bottom-left corner with an excellent finish to leave Everton battered and bruised.
