Newcastle's self-implosion in the form of a first-half sending off and second-half own-goal Fabricio Coloccini will deflect attention away from another listless attacking performance by Arsenal.
The Gunners had 22 shots but only nine were on target as they struggled to make the most of their 74% of possession. That said, the Geordies made 15 fouls and collected six yellow cards in addition to Aleksander Mitrovic's dismissal in the 16th-minute.
Against Arsenal he was at it again as a high foot which could be described as a 'striker's tackle' caught tough tackling midfielder Francis Coquelin. The third time proved to be the charm as referee Andre Marriner sent him off.
Steve McClaren's men had not defeated Arsenal at St James' Park for ten years and once they went down to ten-men that record looked like increasing to 11 years as an attritional approach killed the home side's attacking ambition - they only recorded one shot all game.
The Gunners huffed and puffed but struggled to blow the house of the Toons down until Coloccini's own-goal in the 52nd-minute. The goal came from Aaron Ramsey's shot from 20-yards which was saved by Tim Krul but the rebound fell to Alex Oxlade-Chamberlain's shot from inside the box which deflected off Coloccini into the back of the net.
The loss leaves Newcastle without a win in four Premier League games and hovering above the relegation zone, whilst Arsenal are in the top half of the table with seven points.
