Former Premier League referee Dermot Gallagher has insisted referee Paul Tierney followed the right protocol in allowing Pierre-Emerick Aubameyang to retake his penalty against Norwich City.
The Arsenal star saw his penalty kick saved by Tim Krul initially.
However, VAR reviewed that the penalty should be retaken with players from both sides encroaching on the spot-kick.
Aubameyang then scored the second penalty to draw Arsenal level in the match after Teemu Pukki had put Norwich ahead.
The Gabonese frontman grabbed his second later on to rescue an equaliser as life after Unai Emery began with a 2-2 draw.
The decision of the VAR and Tierney came under much scrutiny from the media and supporters, with many feeling the decision offered an unfair advantage to the attacker.
However, former PGMOL ref Gallagher has insisted that the correct verdict was reached as it was a Norwich player who had a direct outcome on clearing the ball after Krul saved the penalty after encroaching.
"Max Aarons has encroached, and has a direct impact on the outcome, as he's the player who has cleared the ball, stopping an Arsenal player coming in," Gallagher explained on Sky Sports News Ref Watch.
"If an Arsenal player was first to meet it, and put it over the bar, I'd suggest they would give a goal kick.
"The ref would have to decide who has encroached - if there was encroachment, but a player who hadn't encroached had cleared the ball first, it wouldn't have been retaken."
Gallagher, however, was undecided on the referee's decision to book Kenny McLean for a studs-up challenge on Matteo Gunedouzi.
The Norwich midfielder was only shown a yellow card, rather than red, for the tackle, which some thought was incorrect.
He added: "I think if he'd have got sent off, he couldn't complain. This is right on the cusp, some would send-off, some would give a yellow."
