Lucas Torreira's spectacular winner ensured that Unai Emery’s men claimed their tenth win of the season.
Across all competitions, the Gunners have now gone 20 games without a defeat.
The Emirates Stadium outfit last suffered defeat in August against Chelsea and the Nigeria international who made his 13th league appearance against the Terriers has taken to the social media to revel in the impressive showings by his side.
“Unbeaten run continues,” Iwobi posted on Instagram.
Iwobi will hope to get another chance to impress when Arsenal take on Qarabag in Thursday’s Europa League tie.
