Tom Fellows spins in midfield and drives towards the area before eventually being felled in the D by Alfie Gilchrist who picks up a yellow card for his trouble.

Danger for the Blades...

Callum Styles concedes an early corner which Harrison Burrows whips in from the right, eventually finding Tyrese Campbell at the back post.

He lofts the ball back into the middle but Jesurun Rak-Sakyi gets his timing wrong and sends his header back across goal rather than goalbound.

David Webb gets us back under way...

Storm Darragh might be a few hundred miles east now but the rain has intensified at a very chilly Hawthorns during the interval. A couple of degrees away from the white stuff, I'd wager.

The teams are back out from the shelter of the dressing room and will hopefully serve us up another treat in the second half...

How does this look Blades fans?

Two shots, two goals, three points? We'll see if that comes to pass in the second 45 minutes, but for now, drink this in...

West Bromwich Albion can be forgiven for wondering what has hit them here.

One-nil up and, let's be honest, looking quite good for it.

And then, wham bam, two Hqrrison Burrows crosses later and the Blades had cut through the Baggies like a knife through butter.

Two former Midlanders too, Callum O'Hare and Tyrese Campbell, both back on their old patch after moving north in the summer - and now back here having an impact.

It will be hard to know what Carlos Corberan can say at half-time - as his side did not really do a whole lot wrong for most of that first half!

They were two instinctive finishes from Sheffield United.

You put it in there and Tyrese Campbell will be there.

Yes, West Brom are at home and they're going to have a bright start but you have to get at them.

What a first half.

The Baggies completely bossed the opening half-hour and were more than good value for the lead given to them by Torbjorn Heggem's header, his first goal since his summer move to The Hawthorns.

But after Callum O'Hare poked the Blades level from close range with their real chance of note, it's been all Sheffield United and Tyrese Campbell completed the turnaround by sliding home Harrison Burrows' cross.

Two minutes of added time. The Baggies will just want to get in the dressing room. Although they'll have a furious Carlos Corberan awaiting them, most likely.

It's been unbelievable how the game's turned on its head.

Albion have to dig deep and reorganise, get back to what they were doing in the early stages of the game and make sure that Sheffield United don't get a third.

I'd love to be a fly on the wall in the West Brom dressing room when the half-time whistle goes.

Well that's put a bit of a different complexion on things.

As two goals in as many minutes always does.

Only three visiting players had previously netted here this season.

Now the Blades seem to be almost queueing up to score!!!

Football does this . . .

Goodness me, it's almost 3-1...

Sydie Peck controls Gus Hamer's pull-back on the edge of the box but his measured curler floats just over.

The Baggies have gone from in control to in a mess.

Sheffield United have turned this game on it's head in the West Midlands.

That is a striker's goal from the man of the moment Tyrese Campbell. That's his sixth goal in eight games.

West Brom took the lead but Sheffield United and grown into it.

They've had to be patient but it's a fantastic response.

It's a great give a go there.

We don't care it goes it but Callum O'Hare there just to prod it home.

That's what he gives you, he's there in the right place.

Better from the Blades once again. Gus Hamer's first-time effort from a right-wing cut-back from Tyrses Campbell is blocked by Kyle Bartley's outstretched leg.

The temperature ramped up after that dive and it's fired up the visitors.

There's a bit of contact there but he's gone down too easily.

It was a lovely give and go and he's in and you'd argue he's better placed to stay on his feet.

Better from the Blades as Jesurun Rak-Sakyi is played in down the right of the area and wins a corner off Femi Seriki, their first of the game.

The corner is cleared before eventually being returned to Rak-Sakyi by O'Hare. The Blades man thinks Jayson Molumby is going to wipe him out and tumbles to the turf but Molumby doesn't touch him and referee David Webb books Rak-Sakyi for a dive.

Karlan Grant tests Michael Cooper with a more orthodox 20-yard strike towards the opposite corner, which also took a slight deflection, but the Blades stopper once again gets down well to gather.
