Arsenal's top four hopes were dealt a blow when they were held to a 0-0 draw by Burnley on Sunday at the Emirates.
With both sides struggling to fashion many clear-cut chances, one of the main talking points from the game came in the first half when Kieran Tierney and Ashley Westwood clashed.
Tierney went to ground to win the ball, and Westwood arrived a little too late before catching the Arsenal left-back on the shin.
The Burnley midfielder was booked for the tackle, but some Arsenal supporters felt that this was too lenient and wanted VAR to intervene to advise referee David Coote to show Westwood a red card.
