Notice the positioning of the Referee and the AR
Referee Mike Dean has recently performed magnificently in the EPL (e.g. see Mike Dean Masterclass Display Part 1 and Part 2; as well as Mike Dean's Manchester Delight Part 1 and Part 2). Therefore, it was a big surprise to see this scene (above). Perhaps this is due to the lack of penalty kicks from the mark that Dean and his AR encounters … but still, there should be no excuse for not knowing the standard positioning for kicks from the penalty mark.
