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.

What to watch: Monitor PGMOL response and Arsenal's next title-race fixtures.
