Full time: Manchester United 1-0 Sheffield United

Sheffield United are throwing everything forward now but the Depay is able to intercept and break up the move. He dallies on the ball a tad too long and is on the receiving end of a rough challenge. It won't matter too much, the final whistle is about to go...

Rooney sends Long the wrong way and United lead! On the penalty, there did look to be slight contact when Hammond slid in, but Memphis' fall was ridiculously exaggerated.

Goal! Manchester United 1-0 Sheffield United (Wayne Rooney, 90+)

United have a penalty! Depay beat his man cutting in from the left but looked to have taken a dive!

PENALTY - Manchester United

Six minutes of time added on. Can Manchester United draw? The always draw.

Memphis has another go from range, cutting in from the left past Brayford but his low drive again veers just wide.

Martial denied! The ball falls kindly to the Frenchman who lashes one on goal but it is brilliantly blocked by Brayford. The ball spills for Smalling but he connects with fresh air with a wild swing and the chance is gone. Two minutes of normal time left.

Martial slips away from Basham but is quickly swarmed by three Sheffield United players as he tried to find his way to goal. United free kick which Pereira will swing in.

Schweinsteiger trots back on; looks like that wasn't as bad as first feared.

The stretcher is out but Schweinsteiger limps off instead. United have already used all three of their subs.

Pereira floats a ball into the box that Lingard knocks back excellently into the path of Martial but just as he is about to pull the trigger, Hammond makes a brilliant block. Schweinsteiger goes in for the loose ball but is left in agony on the floor after getting a whack to the knee.

This has been utterly, utterly hopeless from Manchester United this evening. They have 10 minutes left to find a winner but haven't for one second looked like scoring.

And here it is, Pereira comes onto replace the hugely ineffective Fellaini.

Looks like there will be another change for United soon with Andreas Pereira now getting ready.

Lingard works the ball inside from the left to Fellaini who shifts it onto Schweinsteiger who winds one up from outside the box. His connection with the ball is woeful however and he slices a shot well wide.

Memphis has given a slight lift to his side since coming on. He drives in from the left, skipping past his man before pinging a cross in but it's deflected for a corner. United do nothing with it.

Darmian shows a wonderful bit of skill to clip the ball away from an onrushing defender as he reaches for a loose ball inside the box but he can only toe poke a tame shot on goal in the end. At least it's one on target.

Now we've got one! Chris Basham slips past his man and tries a shot from 20 yards out but it's driven straight at De Gea. 66 minutes in.

No shots on target again, by the way.

Depay comes close! Passing isn't working so the Dutchman lets fly with a powerful effort from 25 yards out that veers just wide of Long's post.

Now it's a change for Sheffield United as Billy Sharp comes off for Ryan Flynn. Sharp is not happy with that.

Van Gaal is changing things up, Memphis Depay and Jesse Lingard are on for Ander Herrera and Mata.

Sheffield United almost catch the home side out as Paul Coutts slips inside Borthwick-Jackson down the right but his ball across goal is forced away by United.

Mata drives in from the right and tries to clip a ball into Fellaini whose waiting inside the box but Edgar is well placed to nut it clear.

United have picked up from where they left off. Pass pass pass, not a lot of them going forward. Yawn.

Herrera lifts a ball out to Mata on the right flank in plenty of space. He has the time to lift in a precise cross but instead floats it straight into Long's arms.

And we are back underway at Old Trafford.

Half time: Manchester United 0-0 Sheffield United

Martial is clipped out on the left and United have one more chance to work something. It's dragged back to Blind in a move we have seen a few times this season where the Dutchman breaks away to take the shot on. It worked when he found the back of the net against Liverpool in December, it doesn't this time when he skies it over the bar. And that will be that for the first half.

Brayford works a little space for himself down the right and whips a vicious cross in that De Gea has to scamper across to claim. Three minutes of time added on in this half.

Rooney hammers it into the wall and the chance is gone.

What a waste of a set piece. The short one comes to nothing so Mata picks the ball up and pings a pass into the feet of Herrera, who can't control it quickly enough. Luckily for them, they now have another free kick closer in after a blatant handball from Hammond. Rooney and Mata stand over it from about 30 yards out.

United ponderously come forward again but this time Juan Mata is fouled after neatly jinking outside Hammond. Free kick for the home side.

Schweinsteiger makes a great run into the box to latch onto the end of Rooney's lofted pass but goes down after the slightest touch from McEveley who is coming in behind him. Was that enough for a penalty? The referee doesn't think so and waves away the German's appeals.

Herrera plays a nice pass inside from the right for Rooney but Edgar gets across to intercept. Moments later the skipper is almost in again as Schweinsteiger threads one through the middle but Long is out to smother the ball before Rooney can get there first.

More of the same in these last few minutes. Pass pass pass from United but they are getting nowhere quickly in front of two banks of four in red and white. Rooney tries to slide one up the touchline for Martial but it's an ambitious ball that the Frenchman cannot get on the end of.

Fellaini is well placed on the line to clear that corner at the near post and United spring forward on the attack but it breaks down when Martial is tackled by Brayford.

Darmian is forced to head clear for a Sheffield United corner.

Darmian plays an excellent ball from the right in for Rooney to run onto and the skipper gets to it ahead of Long, rounding the goalkeeper. He is forced too wide for the shot and instead tries to play a pass across goal but it's blocked by the first man and Sheffield United survive.

Rooney now has a crack from distance but he spoons it well over the bar.

Connor Sammon shrugs off Blind, takes the ball down and lashes a shot on goal that needs De Gea to palm over. Great control from the forward, but it doesn't count when you use your hand, as he just did.

United are completely dominating possession at the moment but are yet to find a way through the League One defence.

Schweinsteiger slides an excellent ball through for Martial who is immediately swarmed by three Sheffield United players. He tries to jink his way past the lot of them but eventually someone gets a foot in to dispossess him.

Sheffield United have a lot of men behind the ball everytime United venture forward. Borthwick-Jackson is picked out on the left wing and drills a ball across goal but it is hooked away by Edgar.

Darmian cuts the ball back to Mata who swings a delicious inswinging cross into the box, looking for Marial who has peeled off his man near the far post. The Frenchman can't quite stretch far enough to bring the ball under control however.

A neat move from United sees Herrera slide a clever ball through for Rooney but he drags the ball away from goal, taking away the shooting opportunity. The ball is eventually worked back to Fellaini on the edge of the box but his attempted pass is intercepted and Sheffield United can boot it clear.

Billy Sharp almost sneaks inside Matteo Darmian down the right channel but the Italian gets back inside to shrug him off and get the ball clear.

A bit of a nervous start from United so far. As you can expect, Sheffield United are right in their faces and as a result, the home side aren't holding onto the ball under pressure.

And Manchester United get us underway.

We are five minutes from kick off at Old Trafford. There have been 27 other FA Cup third round games already today, but no real shocks to tell you about. Non-league Eastleigh almost took the headlines when they went ahead against Bolton, but the Championship side fought back to claim a draw and a replay.

Bristol City were within a few seconds of eliminating West Brom until James Morrison scored an equaliser with virtually the last kick of the game.

Elsewhere, Arsenal, Crystal Palace, Everton, West Brom and Manchester City were among the sides to progress to the fourth round of the competition.

Louis van Gaal has opted for a strong XI for this evening's clash. With the exception of Borthwick-Jackson and Fellaini coming in, it is pretty much the strongest side available to the manager.

Of course there is so Adnan Januzaj in the squad today, the Belgian is likely to feature in a couple of Under-21 games before he is considered for the first team having started just two games in the last four months.

Sheffield United side side to face Manchester United: Long, Brayford, Basham, Coutts, Sharp, Collins, Woolford, Sammon, McEveley, Edgar, Hammond

Subs: Howard, Flynn, Baxter, Done, Campbell-Ryce, Reed, Adams

BREAKING: Cameron Borthwick-Jackson comes into the starting XI as Daley Blind moves back in to centre half alongside Chris Smalling.

Manchester United team to face Sheffield United: De Gea, Darmian, Smalling, Blind, Borthwick-Jackson, Schweinsteiger, Fellaini, Herrera, Mata, Martial, Rooney

Subs: Romero, McNair, Varela, Lingard, Pereira, Memphis, Keane

Will the visit of League One Sheffield United help remedy Manchester United's woes in front of goal? Louis van Gaal's goal shy side have scored just five goals in their last seven games and while their 2-1 win over Norwich last week halted their fall somewhat, their performance was still devoid of the attacking flair the Dutchman promised upon his arrival at Old Trafford.

On Friday, Adnan Januzaj returned to the club after Borussia Dortmund cancelled his loan deal. The Belgium international won't be in contention this evening, however. Having started just two games during his brief spell in Germany, Van Gaal first wants the 20-year-old to get his fitness up to grade first with a couple of outings with the Under-21 side

Jesse Lingard is available again however having recovered from a hamstring injury but Phil Jones is once again injured with an ankle injury.

Sheffield United meanwhile have Matt Done back among their ranks after the winger recovered from a hamstring problem of his own.
