Time was rapidly running out for Arsenal.
With 83 minutes on the clock, Newcastle United were still in front at St James' Park courtesy of a powerful header from Nick Woltemade.
And it looked like being one of those days for the visitors.
A penalty award had earlier been overturned following an intervention from the video assistant referee (VAR) after Newcastle goalkeeper Nick Pope appeared to bring down Viktor Gyokeres.
Leandro Trossard saw an effort crash off the post.
Pope made superb saves to keep out a pair of volleys from Eberechi Eze and a header from Jurrien Timber.
