The Spaniard cut back to the near post, where Alexandre Lacazette took a lovely touch, turned, and fired in a 29th minute opener.
This was our ninth consecutive victory in all competitions and we move above Tottenham in to third place in the Premier League table thanks to a superior goal difference.
Fulham's back three looked exposed with every Arsenal attack and only fine work from Marcus Bettinelli stopped Alex Iwobi tapping home a second, but they snatched an equaliser a minute before half-time, Schurrle clipping a fine first-time finish over Leno after a good Luciano Vietto pass.
Aaron Ramsey scored Arsenal's 3rd goal in their destruction of Fulham, and it was a thing of beauty! The Welshman - who had only come on two minutes earlier - chipped the ball past a defender, before heading it towards Hector Bellerin. Aubameyang put the seal on Arsenal's stroll in the autumn sunshine in the 79th minute, deftly converting Bellerin's cross.
Aubameyang completed the rout with a long-range drive in stoppage time.
Lacazette was at the centre of Arsenal's powerful show at Craven Cottage, with his superb second-half strike restoring their lead after Andre Schurrle had cancelled out his opener.
With Ramsey also providing a superb through ball to set up Aubameyang's second - and Arsenal's fifth - his contribution to the win was vast, with all five of Arsenal's goals beautifully worked. And Arsenal are two points behind, yeah? Today we are happy but we're going to continue going about our process with humility. The London gunners last lost a match in August 2018 against rivals Chelsea.
- Lacazette has been directly involved in six goals in five starts in the Premier League so far this season (4 goals, 2 assists).
Substitute Pierre-Emerick Aubameyang got in on the action, grabbing two goals in a memorable 30-minute cameo. They will play Leicester City after the worldwide break and will then make a trip to Portugal to play Sporting CP in the Europa League.
The Gunners have now racked up nine wins in a row and have moved into the top-four.
