Arsenal headed into the away Premier League clash looking to return to winning ways after the north London side were beaten 3-1 by Manchester City at The Etihad last weekend.
The Gunners took the lead in the 16th minute thanks to Alex Iwobi’s opener against Huddersfield.
And Lacazette made it 2-0 on the stroke of half-time when he fired home his 10th Premier League goal of the season.
Sead Kolasinac scored an own goal in the dying moments but Arsenal held on to claim all three points.
Celebrity Arsenal fan Morgan is usually active on social media during Gunners clashes and he was clearly delighted by Lacazette’s display on Saturday.
Morgan wrote on Twitter after Lacazette found the net: “BOOM! 0-2. Lacazette is a lethal Renard 🦊 dans la boite 📦. #htfcvafc.”
The result left Arsenal in sixth place in the Premier League table but just one point behind fourth placed Manchester United.
Chelsea FC have the chance to move back into fourth place when they take on Manchester City at The Etihad on Saturday.
Next up for Arsenal is their Europa League last 32 clash against BATE Borisov away from home on Thursday night.
