Lacazette and Aubameyang secure Arsenal's second win of the season
Burnley started with a good chance through Pieters, but Arsenal were on top early on and Lacazette opened the scoring after 12 minutes. The Frenchman was there at the near post to knock home from a corner after his initial header had been tipped over by the keeper.
Emery's side looked to be comfortable during the first half despite the odd Burnley scare, but the away side levelled through Ashley Barnes. McNeil's pass found the ex-Brighton man and he slotted past Leno to level the scores in the 43rd minute.
The second half started in entertaining fashion with Arsenal being denied by Pope on a few occasions, but Aubameyang was the hero as he scored the decisive goal 18 minutes into the second half. He made a nice run before scoring from just outside the box.
McNeil headed over eight minutes later after Lowton's effort was deflected, but bar the odd scare, Arsenal held on fairly easily to claim the three minutes.
Arsenal now sit top with maximum points from two games while Burnley stay on three points as they won on the opening day of the campaign.
