Read more on the big upset with our match report here, including a Talking Point and player ratings.

Forest knock Arsenal out in this round for the second time in four years. Thanks for following the match with us.

A strange late switch from Arteta.

Arsenal do not look like scoring

Instead it is Forest doing the attacking, with Diaz slipping Grabban in and the substitute seeing his shot blocked.

McKenna assured the Arsenal defender could not get a clean connection on Cedrics cross.

Grabban finishes first time to put the Championship side in front. A fine cross from Yates after Lokonga gave the ball away in midfield and the substitute's finish was superb.

But Worrall gets in front of Lacazette and the Arsenal striker cannot get his foot to the ball.

A bit of collateral revenge, though it was on Tiernay rather than Martinelli.

Cafu replaces him. Not that one...

Spence ran away from him and Odegaard and inside Holding before the Brazilian fouled him.

And puts it straight out for a goal kick.

He will have an opportunity to put this in the box now.

Patino the man to come off. It could have been any of the forwards or midfield really.

Grabban replaces the new signing.

But lashes the ball against the side-netting from a narrow angle.

You have to think Arteta will strengthen the side shortly.

A free kick from almost 30 yards out but it was curled over the wall and towards the top left hand corner but Leno parries away.

Saka hung a fantastic cross to the back post for Nketiah but he totally mistimes his header and it goes back across the goal.

A fine run down the right by Johnson and his cross is hit first time by Zinckernagel but Leno parries away diving to his left.

But the defender blocks the effort from the Arsenal striker.
