Mikel Arteta revealed the assistant referee immediately told him that Anthony Taylor had got the decision to award Burnley a penalty in Saturday's Premier League clash.
Arsenal goalkeeper Aaron Ramsdale had caught Matej Vydra and a spot kick was awarded but VAR intervened and after Taylor went to look at the pitchside monitor the decision was overturned.
It ensured the Gunners held on for the points and Arteta felt the spot kick reversal was the right one.

"The assistant was saying straight away it’s not a penalty," said the Gunners boss. "You have to overturn that."
While Burnley are still waiting for their first win of the season, Arsenal have now picked up successive 1-0 victories to climb the table.
And the Gunners chief was delighted with his side's resilience against a Clarets outfit that posed problems.
"A really hard-fought victory in a place that it is tough to come to and win," Arteta added.
"They do really well with what they do. They put you under a lot of pressure but I think we started the game really well, controlling and dominating the game.
"We had some big phases where I saw a lot of things that we want as a team.
"We scored the goal, had some opening chances and then there were moments where we lost control and started to give balls away after the second or third pass. Then the game becomes open and there is no control.
"They split the two blocks very much and then you have to defend crosses and long balls. I thought that we did that really, really well.
"We have players that are not in the best quality to play that game but I think that they did terrifically well and the commitment and the attitude that they showed throughout the game to find a way to win was the most pleasing thing for me, after the game."
