Full-time: Nottingham Forest 4-2 Arsenal
Walcott can't make it three! Nketiah pounces on a dreadful pass back and tries to clip the ball over Smith. It's a good attempt, but Smith does brilliantly to get a hand onto it, pushing it over himself and sending it rolling out for a corner. Walcott is racing to get onto the ball before it does that but he can only hammer into the side netting from an impossible angle.
Four minutes of injury time have been added on.
Good grief, this game has everything now. Joe Worrall is shown a second yellow card after crashing through the back of Akpom.
RED CARD - Joe Worrall
Another change for Arsenal, Chuba Akpom is on for Debuchy.
After consulting his assistant, Moss awards the goal! Dowell slipped and almost made a mess of his spot kick and Arsenal were adamant he had touched it twice as he slipped. He stuck it past Ospina anyway and the goal stands.
But wait, has it been given? Dowell slipped as he struck it, was there a double touch?
Goal! Nottingham Forest 4-2 Arsenal (Kieran Dowell, 84)
Another penalty for Forest! A dreadful ball out from the back is pounced upon by Traore who bursts forward, skipping past Mertesacker like he isn't there. Debuchy tries to stop him in the box but the foul is given and Jon Moss points to the spot!
PENALTY - Nottingham Forest
Arsenal pull one back! Welbeck races onto a ball down the inside left channel that Smith looks to have covered, racing out of goal to smother the ball. Somehow it slips through underneath him and Welbeck is there to roll the ball into an empty net.
Goal! Nottingham Forest 3-2 Arsenal (Danny Welbeck, 78)
Walcott lifts a deep ball in and there a soft appeals for a penalty that are ignored.
Arsenal now have a free kick out on the right wing that Walcott will swing in.
Forest are embarrassing Arsenal's backline at the minute. Dowell, for good reason, fancies his chances against Mertesacker and easily beats the big German before cutting a ball across goal looking Brereton. This time he isn't there waiting for it however and the Gunners clear.
Smith denies the sub Nketiah! Welbeck does brilliantly to slide a ball through for the 18-year-old, who brilliantly spins past his man but his low drive is well saved by the Forest goalkeeper.
Arsenal respond by throwing on Eddie Nketiah who replaces Willock.
And Forest have three! Brereton demands the ball and sends Ospina the wrong way. Perfect penalty.
Goal! Nottingham Forest 3-1 Arsenal (Ben Brereton, 64)
Penalty for Forest! What a nightmare for Rob Holding; he sticks out a leg that sends crashing to the turf. Easy decision.
PENALTY - Nottingham Forest
Brereton once again gets the better of Holding, scampering in front of him out on the byline and winning another free kick for his side.
