Sheffield United are the ones who are now tallying up the chances.

Nice work from Chris Basham finds Morgan Gibbs-White on the right. Sander Berge is then teed up at the top of the box, but the Norwegian can only blaze over the bar as he goes looking for the top corner.

Oliver Norwood finds his way into referee Andre Marriner's book. He is all over Jack Colback as the Reds man is brought down with a thump.

Colback's early goal continues to separate the sides.

Joe Worrall is trying to do the business at both ends.

One moment he has a low shot from the edge of the area blocked, then he is backtracking at pace to stop Morgan Gibbs-White on the counter attack. It's proper action man stuff from the Reds captain.

Forest have the edge over Sheffield United for legs in midfield. When the ball breaks they are a bit sharper.

At the moment that physicality is tipping the balance but hopefully Sheffield United's quality will tell because that's what they have an abundance of.

Another Sheffield United chance, and another big Forest block.

This time Steve Cook stands in the way of a Chris Basham effort after the Blades man was afforded time and space to shoot in the area.

Sheffield United have started the second half much better.

When you're under pressure sometimes you have to put your bodies on the line, and Forest have done that a few times already.

Sheffield United patiently work a chance on the edge of the area.

From Chris Basham on the right, the ball goes back to Sander Berge before Ben Osborn has a go from the top of the box. Joe Worrall, however, throws himself into a crucial block.

Will it remain all one-way traffic in favour of Nottingham Forest in the second half?

Early indications are that the Blades have fight in them, as they have the Reds pressed back.

And off we go again.

The second half is just a few moments away.

Both sides have emerged from the tunnel. Chants from the home fans hit a crescendo as the Blades come out.

Willem Mevius: Amazing that Sheffield Utd are still in it, but I don't give them much of a chance. Forest look like Premier League quality, while the Sheffield Utd side looks worse than the one they got relegated with last year.

Paul Heckingbottom will need to get into Sheffield United at half-time.

He will have been happy with the first 10 minutes but since then they've lost their pattern of play.

It's been an outstanding first half by Forest. Sheffield United can't cope with the movement of Forest in this blazing heat, they're looking heavy-legged.

It's unbelievable how Forest are only going in with one goal. That's my only negative - otherwise they've been perfect. It's been sheer dominance from Forest.

And that's the end of one pulsating and tense half of football at Bramall Lane.

Jack Colback's cool, close-range finish has Nottingham Forest leading, but the Reds will wonder how they haven't buried a few more of their big chances.

We are into the first of three minutes of injury-time.

Chris Basham concedes a corner, but Sheffield United repel the danger.

What did I just say about tension?

Nottingham Forest's Djed Spence and Sheffield United's Jack Robinson get into it a little bit after falling over one another in a challenge. Both players had a fist full of shirt and both are shown a yellow card.

The tension in the game is starting to show.

Philip Zinckernagel is the next to be booked for his challenge on Iliman Ndiaye.

Wes Foderingham makes a decisive double save.

First he manages to parry an effort from Sam Surridge before collecting himself to foil Brennan Johnson's close-range shot on the rebound.
