Only if you believe he deliberately touched the ball as per the IFAB wording. He certainly didn't make his body "unnaturally bigger"
It is an offence if a player:
deliberately touches the ball with their hand/arm, for example moving the hand/arm towards the ball
touches the ball with their hand/arm when it has made their body unnaturally bigger. A player is considered to have made their body unnaturally bigger when the position of their hand/arm is not a consequence of, or justifiable by, the player’s body movement for that specific situation. By having their hand/arm in such a position, the player takes a risk of their hand/arm being hit by the ball and being penalised
I'd argue if you are turning your back on a shot blasted at you from 3 yards away, there is not deliberate touching of the ball or unnatural "biggening"
Especially using this season's interpretation that are supposed to include a little more common sense.
The fact that the ref had a clear view and didn't award it suggests to me he was OK with it too and only felt like he had to give it when he was summoned by VAR.
