The Gunners succumbed to a fourth straight home defeat in a game which saw Granit Xhaka sent off and Pierre-Emerick Aubameyang score an own goal.
So who impressed and disappointed on the night?
✔️ GOOD PERFORMANCE
Matthew Lowton: 7.5
He made a game-high six interceptions, while his seven recoveries were only bettered by one outfielder; Robbie Brady.
❌ BAD PERFORMANCE
Granit Xhaka: 5.9
Xhaka was Arsenal's best player last week but, for the umpteenth time in his Gunners career, a complete lack of discipline cost his side dear.
Pierre-Emerick Aubameyang: 5.9
Aubameyang finally ended his long run without scoring a goal - unfortunately it was in the wrong net.
The Gabon international disastrously put through his own goal, heading past Bernd Leno with 16 minutes remaining to condemn Arsenal to yet another defeat. In attack, he did manage four shots and two on target - but nothing is working for the striker right now.
⭐ STAR MAN
Nick Pope: 8.4
The 28-year-old made six stops to keep Burnley in the match and pave the way for a crucial victory in their fight against relegation.
