The visitors now have a free-kick - about 45 yards from goal.

What can they do with this?

No, because Harry Maguire can't keep the ball in after his team-mates make a mess of the situation.

Bit of pressure from Manchester United - they win their first corner of the half.

Will Jones make amends?

John Fleck has scored two league goals at Bramall Lane this season, one more than he did in the whole of last season in the Championship (one goal in 23 appearances).

Great pressure so far from Sheffield and they are excellent at keeping the ball. They are moving the ball from left to right, not rushing. Everyone knows their jobs and now they have another corner. Since the goal, there has been no let off since their goal.

Another corner for the Blades after John Lundstram's cross is cleared Fred.

It's dealt with but Solskjaer's men can't get out of their own third.

Yet another corner for the home side - United counter but Daniel James' crossfield pass drifts out.

Pablo Sanchez: I'm not the biggest Phil Jones fan (who is), but how on earth was that not a foul in the lead up to Sheffield Utd's goal? What's the use of VAR if not to pick up instances exactly like this?

Manchester United are giving the ball away far too cheaply. It's taken them 29 minutes to test keeper Simon Moore who is making his first Premier League start in place of Dean Henderson. Ole Gunnar Solskjaer needs to change something because it is Sheffield United who look more likely to score the next goal.

The Blades, once again, are causing havoc on the wings and with their crosses.

On this occasion the visitors manager to get away with it following a wicked delivery from Oliver Norwood.

Manchester United have failed to keep a clean sheet in 12 consecutive top-flight away games for the first time since a run of 15 in the 1985-86 campaign.

Manchester United produce their first shot on target!

It comes from the boot of Anthony Martial, although it's a bit of scuffed one from the edge of the area.

Keeper Simon Moore could have nipped out to do his shopping before saving that.

A word about Lys Mousset. A few weeks back Chris Wilder said that the forward was not quite match-fit and challenged him to get into better condition.

He's already proved himself today.

Meanwhile, Phil Jagielka's taken out goalscorer and his team-mate John Fleck - but he's OK.

The Blades are sharpened again!

This time David McGoldrick glides forward before striking a low 18-yard shot which is held by David De Gea.

The Spaniard might prove to be Solskjaer's most important player today.

Jack Lovatt: Mousset looks a player reborn at Sheffield United compared to at Bournemouth, game on!

Aditya Thakkar: Manchester United had that coming.

Sheffield United are just loving life in the Premier League. They've come out snapping and snarling at Manchester United and now they have the lead.

There is a debate raging in the press box as to whether Lys Mousset fouled Phil Jones in the build-up.

But make no mistake - the Blades deserve the lead.

Olamide: Solskjaer's tactics not working one bit. We're being overrun in the midfield and he has to do something about it fast before we go 2 nil down.

Shane O'Neill: De Gea brilliant today, but the defence are simply awful. Would be nice if Utd turned up. Midfield is non-existent

That was almost 2-0!

Goalscorer John Fleck whips in a beauty of an in-swinger - Fred gets his head to the ball and it whistles past the far post.

Nothing comes of the corner much to the delight of the visitors. They could do with HT now - but they have to wait another 23 minutes.

It's a goal Sheffield United deserve, especially after the double save from David de Gea. What was so impressive was how quickly they got players forwards and in numbers. I think that's really worrying though that VAR has not picked up on the fact that Phil Jones was bundled over. Is that not a foul? I think so.

The Blades were very short on numbers there as Daniel James sped down the right.

His cross was cleared by Chris Basham in the area with Marcus Rashford lurking behind the defender.

Bubbling.
