Pierre-Emerick Aubameyang scored twice as Freddie Ljungberg's Arsenal earned a hard-fought point at Norwich.
Teemu Pukki fired the hosts in front with a 21st-minute effort that took a big deflection off Shkodran Mustafi.
Arsenal quickly had a chance to level the scoreline when Christoph Zimmermann was penalised for handball and the Gunners were awarded a penalty.
Tim Krul saved Aubameyang's initial spot-kick, but the Arsenal skipper made no mistake after VAR intervened to order a retake for encroachment.
But the Canaries retook the lead in first-half stoppage time through Todd Cantwell.
Having cancelled out Norwich's opener, Aubameyang was at it again in the 57th minute.
The ball found its way to the Gabon international from a corner and he fired home another equaliser from just outside the six-yard box.
Here's how they rated rated:
Arsenal
Leno 7
Must get nightmares playing behind Arsenal’s defence. Made three fabulous saves.
Chambers 5
Booked. Off the pace, all the problems came down his side, Hernandez gave him first half.
Mustafi 5
If Emery had picked Mustafi, fans would be going crazy. Struggled badly.
Luiz 5
Dragged all over the place and never seemed to be in position to defend.
Kolasinac 6
Familiar problem of being great going forward but was exposed defensively.
Guendouzi 6
In the wars as he took several heavy blows, plenty of energy but lacks
Xhaka 6
Has his limitations. But Arsenal look more secure with him in midfield. Yes, really.
Willock 6
Lost possession in build-up to Norwich’s first goal. Drove forward but limited effect.
Ozil 6
Started brightly, but guess what? Faded when the going got tough. Frustrating.
Lacazette 6
Showed great strength and hold-up play was good but never looked like scoring.
Aubameyang 7
Where on earth would Arsenal be without him? In the relegation zone, probably.
