It's a double substitution with one for each side.

Man Utd's Fred comes on for Nemanja Matic while Harvey Barnes replaces Demarai Gray.

On we go...

Ashley Young is alert to the danger as he puts James Maddison's in-swinging cross behind for another Leicester corner.

Despite all their possession after the interval, the visitors are yet to register a second-half shot on target.

Manchester United are on the back foot here.

Unless, Ole Gunnar Solskjaer can change the narrative, an equaliser looks inevitable.

Solskjaer has talked a lot about 17-year-old forward Mason Greenwood over the past few months.

Surely it is time to bring him on.

Leicester have grown into this game the longer it goes on. I’ve been really impressed with James Maddison. There has been a lot of talk about him at the start of this season and you can see why. He’s dropped into a deeper central role at the moment and just seems to be full of confidence.

The Foxes are piling men forward now as substitute Ayoze Perez and Ricardo Pereira combine to work room inside the Man Utd area. before Harry Maguire comes across to win the ball.

It's all to play for as we tick past the hour mark.

Leicester make the first change of the afternoon as Hamza Choudhury is replaced by Ayoze Perez.

The visitors are going to go for this now.

Man Utd go up the other end at a canter and win a corner off Ricardo Pereira.

Harry Maguire rises highest to meet Ashley Young's ball in but his header is into the ground and lacks the power to beat former teammate Kasper Schmeichel.

That would have been one for the books.

Manchester United started well, they got the early goal. In the first 20 mins they were really engaging and closing down really well but then they started to tire. It will be interesting to see how they do in the second half.

Harry Maguire has taken quite a bit of stick from the Leicester supporters today but he silenced them with an excellent piece of defending just then.

With Demarai Gray threatening inside the Manchester United half, Maguire strode across, made an excellent half block, before regaining his balance, turning back to Gray, shrugging him off the ball and striding effortlessly away.

Excellent stuff.

Scott McTominay is penalised for a late tackle on Youri Tielemans just on the edge of the Man Utd box.

James Maddison stands over the subsequent free-kick and he and smashes the ball just inches wide of David de Gea's left upright.

Chance.

They let Leicester back into it in the first half but when they’re playing at top tempo, Manchester United look like a really top side.

Apart from Marcus Rashford's goal, that may be the loudest cheer of the day.

Demarai Gray sprints onto Youri Tielemans's through ball but Harry Maguire steps across to win the ball.

The big centre-half then pulls off a Cruyff turn to evade Gray as he attempted to win the ball back.

Man Utd go straight up the other end and the impressive Daniel James cuts in on his right before firing over the bar.

The Welshman is hoping to become the first Man Utd player to score on his first three home appearances since... his manager.

Gareth Southgate is watching on but I wonder what he will have made of Harry Maguire's performance so far?

The England centre-back loses out to Jamie Vardy by the byline as the Leicester forward drills the ball across the face of goal, but there were no blue shirts in the area.

Let off for the hosts.

Leicester have started brightly ad they pump a long ball forward for the onrushing James Maddison, but it just evades the forward as David de Gea is sharply off his line.

Brendan Rodgers must have had a stern word at half-time.

And we're back underway...

Right then, both sets of players are back on the field and we're all set for the second-half.

Leicester have grown into this game. Both teams have shown a lot of respect. Leicester have had some good play without having the quality on that final ball. Manchester United have been the same.

They may be behind but Leicester manager Brendan Rodgers will be reasonably happy at how that first-half ended.

His side have taken control of possession and carried a much greater threat.

It is a similar game to the one they drew at Chelsea, when many observers felt they were hugely unlucky not to win.
