Arsenal took a 3-1 lead over Tottenham shortly after Emerson Royal’s challenge on Gabriel Martinelli which saw Anthony Taylor hand the defender a red card.
There was a pause in play shortly after Emerson had committed a foul, as Martinelli stayed down due to the injury inflicted on him by his fellow Brazilian. However, this break in play ended when a red card was given as a result of the challenge.
Despite protests by some of the Tottenham players, referee specialist Peter Walton explained on BT Sport why a red card was handed to the full-back.
