What happened
Mikel Arteta said Newcastle goalkeeper Nick Pope warranted a red card for denying a goalscoring opportunity. He refrained from complaining after a prior Arsenal loss but spoke out despite Saturday's win. Arteta argued the call would be made if situations were reversed.
Why it matters
The remarks highlight ongoing refereeing debates in the Premier League title race, where Arsenal reclaimed the top spot. As previously covered, Arteta has raged at missed reds involving Pope and a City defender amid the push.
