Bukayo Saka was quickly made to regret a playful dig aimed at his England teammate James Maddison during Sunday's 2-2 draw in the North London derby.
After the Arsenal winger's cross was turned into the goal by Cristian Romero, he ran to a nearby camera and performed Maddison's famous dart throwing celebration.
It seemed an amusing touch from a Gunners side who were well on top, but Maddison had his revenge just 15 minutes later.
The former Leicester man came forward down the left just before half time and found himself one-on-one with Saka.
