Turner has his head in his hands. He gets a touch but it squirms through him. Forest fans stop their cheers.

Moussa Niakhate
Nice. The keeper goes the right way but the kick is over his diving body.
Nahki Wells
No problems here as he places it to the right to keep City in the hunt.
Neco Williams
Another good Forest penalty, to the right and beats the keeper.
Sam Bell
A lot of whistles from the fans as he steps up, and the keeper goes down to his right to save the kick.
Callum Hudson-Odoi
Confident penalty, as the keeper goes the wrong way.
Harry Cornick
Same spot as Forest's, but the keeper goes the other way.
Morgan Gibbs-White
Bottom corner. Keeper guesses right but can't stop it.
Forest will take the first spot kick.

Drama is never far away in the FA Cup and we've certainly got it at the City Ground.
Who is going to hold their nerve and advance?

How good has he been, Nahki Wells since he has came on the pitch.
The ball is just running away from Harry Cornick, it just goes past the post.
Nottingham Forest 1-1 Bristol City
And another chance for Bristol City!
Harry Cornick puts it wide after Nahki Wells' driving run.
Incredible. How are Forest still on level terms?
FT: Aston Villa 1-3 Chelsea
Chelsea
Chelsea defender Ben Chilwell, speaking to ITV: "It was exactly the reaction we wanted and needed. It wasn't about wanting a reaction. We needed it. Fair play to all of the boys."
"We wanted that pressure. We thrived off it. The confidence before the game in the changing room was the best I have seen it - the togetherness.
"We delivered on the pitch today.
"As a club, the players, manager, the staff, the fans everyone involved in the club. It wasn't just the manager. Everyone associated with the club needed that today."
Nottingham Forest 1-1 Bristol City
Bristol City will be kicking themselves if they do not get the job done.
They've had so many chances.

What a pass from Joe Williams. Wonderful.
You think they are going to score. What an opportunity missed.
Nottingham Forest 1-1 Bristol City
That was a huge chance for Bristol City.
Forest are very lucky to still be on level terms. Nahki Wells should have scored.
Nottingham Forest 1-1 Bristol City
How did that not go in!
Bristol City get in behind the Forest defence and Nahki Wells looks certain to score but he gets his legs in a tangle and cannot score.
