Paul Mullin takes on a left footer. That's ambitious mind from 25-30 yards and ends up being no more than a back pass for the Sheffield United keeper Adam Davies to collect.

Ben Tozer has two or three attempts launching the ball into the Blades' penalty area before they finally get half a chance with Luke Young's snapshot off target.

This is better from Wrexham. They get down the right flank on the attack and win a throw in the edge of the Sheffield United area.

Ben Tozer time.

Paul Mullin has been absolutely everywhere. There was space opening up and he elected to take the shot.

Paul Mullin drops deep and then unloads from range. Not enough dip on that mind and it sails over the Sheffield United bar.

Shades of Dave Challinor/Rory Delap from back in the day as Ben Tozer winds up a long throw for the hosts.

Sheffield United clear that easily and Tozer then catches Jayden Bogle, giving him a bloody nose in the process.

The Wrexham crowd was quietened in the opening 10 minutes with everything that went on, but they are starting to get a bit more involved.

Another Sheffield United attack down the right comes to and end as Jayden Bogle jumps into Max Cleworth on the edge of the home penalty area.

It has become much more of an even contest.

Wrexham are looking to play on the counter and Palmer is trying to make himself a nuisance with the three centre backs.

Not a great deal in this possession wise but Sheffield United have definitely carried the greater threat going forward as you'd probably expect given they look well set for a Premier League return this season.

Chris Adams: Hilarious to suggest that was anywhere near a penalty for Wrexham. If anything the Wrexham player’s foot was high attempting to kick the ball as the keeper came for it.

Daniel Jebbison is causing Wrexham all sorts of bother.

The 19-year-old England youth international picks up possession and drives at the home defence before unloading a fizzing shot that looks destined for the far corner until Mark Howard gets a strong hand to parry it away.

Howard did really well. Jebbison just gets it wrong, he's trying to dink it over him but just doesn't get the chip on it.

It's brave goalkeeping and a good early decision from him.

Sheffield United really look dangerous every time they break forward. They work the ball well from right to left and James McAtee sees his effort on goal blocked and loop out for a corner.

Half a chance for the visitors but Tommy Doyle's pass is a shade overhit for Daniel Jebbison and home goalkeeper Mark Howard is out to smother the ball.

They've reacted really well to having two defenders going off early.

The crowd are growing and getting into it and they are playing percentage balls into the box.

Difficult chance for the home side. Thomas O'Connor tries to hook the ball back towards goal after it drops inside the box but gets it all wrong.

I think there is contact. Paul Mullin gets there first but there's not enough in that for me. There's been a good response by Wrexham in the last couple of minutes after falling behind.

Huge shouts from the home side for a penalty as Paul Mullin races on to Anthony Forde's pass.

The Wrexham striker flicks the ball past visiting goalkeeper Adam Davies and tumbles over.

Probably not enough in that for a pen.

Wrexham defender Aaron Hayden is replaced by James Jones, who normally operates as a midfielder.
