The Gunners looked set for a fourth league defeat in eight games until Alexandre Lacazette salvaged a point with an injury-time equaliser.
Aubameyang, 32, played all 90 minutes and admitted that his side were not good enough, with Lacazette's late goal bailing them out of trouble.
The Gabon striker said: “Not enough for a home game. We stopped playing after the first goal but we didn't give up & fought till the end.
"Big help from the guys that came in. @LacazetteAlex well deserved my bro. We go again #COYG."
