57' The home side are playing the game at their leisure. It is difficult out there for the Blades to inject tempo into the game because of the heat.
55' WIDE! Fernandes picks out Greenwood in the box and he opens up space to fire at goal on his left foot. Jagielka is there for the visitors to just get enough of a deflection on his effort to divert it past the post.
53' United are applying pressure after the early chance for the Blades. They're keeping the visitors penned in their own half.
51' Stevens and Moore are on the same page at the back, forcing the former to clear behind from a looping cross into the box.
49' CHANCE! Basham has space down the right flank and he hooks a cross towards the near post. McBurnie is there in space, but he cannot make a clean connection with his header and Wan-Bissaka clears behind.
48' Fleck and McGoldrick almost combine to pick out McBurnie, but Maguire is on hand to intercept a backheeled pass from the forward to his team-mate.
46' We're back underway at Old Trafford.
Chris Wilder's men have been exposed at the back and the loss of John Egan and Jack O'Connell are having an effect this evening. They've been cut open too easily, especially down their left flank. It will take something special for the Blades to respond.
Manchester United hold a 2-0 lead at the break in their Premier League clash against Sheffield United at Old Trafford. Anthony Martial has scored twice from close range, converting an early cross from Marcus Rashford before replicating his effort from another delivery from Aaron Wan-Bissaka. The home side should argubaly be out of sight, with Rashford missed two good openings in the final third. The Blades face a tough time to get back into the contest.
45' + 4' HALF-TIME: MANCHESTER UNITED 2-0 SHEFFIELD UNITED
45' + 2' The home side probe again down the right flank and Fernandes offloads to Greenwood on the edge of the box. He sends an effort at goal, but it's tame and saved with ease by Moore.
45' There will be three minutes of added time.
42' Basham hooks a hopeful cross into the box, but Lindelof is there twice to repel the danger before it travels back to De Gea.
40' United have lost their way over the last 15 minutes. Pogba and Fernandes have not been as influential in the contest.
38' Mousset is struggling for the visitors and he may have to make way here. It does not look good for the Frenchman.
36' Fernandes receives treatment on his knee on the side of the pitch. However, the Portuguese returns to action, although it will be worth monitoring his progress.
35' Norwood whips a dangerous cross in from the corner to the back post where McGoldrick rises, but he cannot make contact with a header.
34' Maguire has to act in the middle to prevent Mousset from latching on to Stevens' low cross into the box. The Blades have a corner on the left.
32' Wilder seems to have got his message across to his players at the water break. The visitors have been a different team since.
30' The Blades work the ball around the final third nicely to create space for Lundstram to strike. The midfielder does not quite catch his effort and it sails comfortably over the bar. It was better from the visitors.
28' Baldock has space down the right flank, but he fails to pick out a team-mate in the box with his cross into the middle.
27' Mousset tries to release McGoldrick down the left flank, but the forward just mistimes his run and is fraction offside.
26' We're back underway at Old Trafford.
25' The referee takes the opportunity to stop the game for the water break.
24' Rashford and Fernandes attempt to combine with a one-two in the final third, but Rashford fouls Baldock in the box and the referee awards a free-kick to the Blades.
23' It has been all action in the opening 23 minutes of the game. Wilder will be concerned about how easily that his team have been exposed at the back by the hosts.
21' DISALLOWED GOAL! Fernandes loops a cross into the box from a corner on the right. Maguire rises to head into the top-left corner, but he shoves Jagielka in the process and the goal is chalked off.
20' CHANCE! Fernandes and Pogba combine to release Rashford through on goal. However, once again the composure of the forward lets him down as he fails to connect with his strike on the half-volley, spurning the opening.
18' SAVE! Fernandes goes for goal from the free-kick and he curls his effort towards the net with power. Moore watches it all the way and palms it wide for a corner.
17' Baldock pulls back Shaw just outside the box on the left flank and the referee awards a free-kick to the home side.
15' The visitors have seen a lot of the ball in the early stages, but have been too easily exposed by United on the counter. Wilder will be concerned on the sideline.
13' CHANCE! Rashford misses a golden chance to double his side's lead. Martial breaks behind the Blades' defence and is through on goal. He slides an offload towards Rashford rather than shooting himself, but the England forward can only guide his effort wide of the right post.
12' United afford Baldock space and time in the final third, and he takes on the shot, only to see his effort blocked by Lindelof.
9' Martial's opener against Sheffield United was his 12th Premier League goal of the season - the most he's scored in a single campaign in his league career.
5' Fernandes whips the resulting corner into the box and Maguire tries to rise to head at goal, but Robinson clears the danger for the visitors.
4' Martial has space on the counter after collecting an offload from Pogba. Basham gets across in time to divert the ball behind for a United corner.

2' Mousset charges upfield and the Blades retain possession in the United half. Lundstram tries to pick out Baldock down the right flank, but the wing-back is caught offside.
1' We're underway at Old Trafford.
Man Utd have won their last seven home meetings with Sheffield United in all competitions by an aggregate score of 17-2, since a 1-2 league defeat in December 1973.
The Blades have rung the changes tonight from their 3-0 defeat to Newcastle. Dean Henderson cannot play against his parent club so Moore makes his second appearance of the season. Jagielka comes into the side in the Premier League for the first time since November to replace the suspended Egan. Lundstram slots into the midfield, while Mousset and McGoldrick lead the line. Sharp, McBurnie and Berge drop to the bench.
United have made three changes to their side from their draw against Tottenham last time out. Pogba returns to the starting line-up for the first time since September 30 after impressing off the bench last week. Greenwood and Matic also come into the fold, while James, Fred and McTominay drop to the bench.
SHEFFIELD UNITED SUBS: Luke Freeman, Oli McBurnie, Billy Sharp, Kieron Freeman, Michael Verrips, Ben Osborn, Jack Rodwell, Richairo Zivkovic, Sander Berge.
SHEFFIELD UNITED (3-5-2): Simon Moore; Chrs Basham, Phil Jagielka, Jack Robinson; George Baldock, John Lundstram, Ollie Norwood, John Fleck, Enda Stevens; Lys Mousset, David McGoldrick.
MANCHESTER UNITED SUBS: Eric Bailly, Juan Mata, Andreas Pereira, Fred, Daniel James, Sergio Romero, Odion Ighalo, Scott McTominay, Brandon Williams.
MANCHESTER UNITED (4-2-3-1): David de Gea; Aaron Wan-Bissaka, Victor Lindelof, Harry Maguire, Luke Shaw; Nemanja Matic, Paul Pogba; Mason Greenwood, Bruno Fernandes, Marcus Rashford; Anthony Martial.
The Blades have not enjoyed themselves since the restart. Their first game back resulted in controversy when they saw a goal failed to be awarded by the goalline decision system and VAR, robbing them of two points against Aston Villa. John Egan's dismissal against Newcastle culminated in a second-half onslaught from the Magpies, with Chris Wilder's men slumping to a 3-0 defeat. They're still in the hunt for a Champions League place, but need to find their form once again.
Manchester United returned to Premier League action against Tottenham last week. Ole Gunnar Solskjaer's men were trailing in the contest, but Bruno Fernandes' strike from the penalty spot earned them a valuable point. It could have been better for the Red Devils, but another late spot-kick was overruled by VAR. United are still five points off the pace of Chelsea in fourth place and level on points with Wolves in sixth. The race for the final Champions League place, which could be awarded to the side in fifth this term due to the uncertainty of Manchester City's ban, will go down to the wire.
Good evening and welcome to the live commentary of the Premier League clash between Manchester United and Sheffield United at Old Trafford.
