The Gunners have been the division’s draw specialists this campaign having been held thirteen times and it looked to be going a similar way after a scoreless first-half.
But the hosts sprung into action instantly after the restart with Eddie Nketiah’s no-look strike from Nicolas Pepe’s cutback clipping the highest of the crossbar.
Mikel Arteta’s side bust the deadlock on fifty four minutes through Pierre-Emerick Aubameyang’s well-placed header and Pepe doubled the lead just 3 minutes later with a neat, first-time end.
Mesut Ozil poked in an exceedingly third late on from substitute Alexandre Lacazette’s pass and therefore the Frenchman converted a fourth in injury-time.
Newcastle tried to play further forward when conceding however were restricted to few opportunities – the dangerous Allan Saint-Maximin returning closest with a curling strike that flustered the post.
Arsenal’s win moves them up into the top half of the table in tenth place – six points behind north London rivals Tottenham, who claimed a last-gasp winner over Aston Villa to go fifth.
