And Everton were back in the game in the 58th minute, when Nacho Monreal handled in the box and Romelu Lukaku converted the penalty.
Both sides had their fair share of chances in an open game.
But both Ozil and Alex Iwobi were guilty of poor finishes when put clean through, and Belgium star Lukaku was not at his sharpest either.
In added-time, Aaron Ramsey showed them the way, bending a superb shot into the top corner.
The season is far from over for the Gunners, however.
There’s the Cup final, of course, and then the saga will no doubt continue over whether Wenger, Ozil and Sanchez will remain at the Emirates.
Of the trio, Sanchez looked the most unhappy yesterday, hurling away his straps and walking off head down and stoney-faced when he was substituted in the 68th minute.
