As Arsenal booted Newcastle United out of the FA Cup, Emile Smith Rowe saw a red card reinstated and then scored the crucial goal.
For Arsenal, Emile Smith Rowe was the hero as they defeated Newcastle United 2-0 after extra time to reach the fourth round of the FA Cup.
For most of the regular time, the holders were bad, which looked to come to an end with Smith Rowe being sent off for a foul on Sean Longstaff.
The VAR, however, urged referee Chris Kavanagh to reconsider the decision, which was reversed, allowing Smith Rowe to make the most of his reprieve by punishing a 109th-minute goal from a wasteful Newcastle side.
The easy strike of Pierre-Emerick Aubameyang added a second and while there is a concern for Arsenal over Gabriel Martinelli, who sustained an ankle injury in the warm-up, the men of Mikel Arteta would be grateful after a below-par performance to have held their defense intact.
The best Arsenal could gather in the first half was a near-post effort from Aubameyang which drew a strong save from the returning Martin Dubravka, and the visitors should have taken the lead after the interval.
After side-footing wide with the goal at his disposal, Andy Carroll was flagged for offside, but replays revealed that the VAR would have reversed the call had he hit the net.
After being played in behind the Newcastle defence, Aubameyang struggled to find the finish and Dubravka proved equal to a Joe Willock header before the Gunners were thankful to Bernd Leno for sending the game to extra-time.
After teenager Elliot Anderson’s attempt had been blocked in his direction, the goalkeeper prevented Carroll from converting.
For a challenge on Longstaff, Smith Rowe was then shown a straight red card, only for the penalty to be downgraded to a yellow.
Dubravka created a display of extra-time acrobatics to tip over the long-range volley of Granit Xhaka but could do little in the second extra period to prevent Smith Rowe, the midfielder handling the header of a fellow substitute Alexandre Lacazette on his chest and firing through the post in a superb finish.
Aubameyang then rounded off a well-worked move to make the game secure, leaving Newcastle to rue their previous missed opportunities.
