- Juan Mata finished off a fantastic team move before Marcus Rashford fired in from close range and Paul Pogba headed home the fourth
- The Foxes improved after the break, with substitute Demarai Gray enhancing his reputation and reducing the deficit with a sensational strike

That is all for this particular live blog, but stay with IBTimes UK for coverage of Liverpool vs Hull in addition to all five other mid-afternoon kick-offs including Tottenham's trip to Middlesbrough and Swansea vs Manchester City.
Sports editor Nick Howson is also your man this evening for that eagerly anticipated and high-profile clash betweenLondon rivals Arsenal and Chelsea. Goodbye for now.
So an emphatic win for Manchester United to allay the concerns of some fans after much hand-wringing in the aftermath of those three consecutive defeats.
They ran riot in the first half courtesy of some truly horrific Leicester defending, although Mourinho may be disappointed with a slightly lacklustre second 45 in which the visitors, boosted by the introduction of Gray, briefly threatened to make things interesting.
Both of these sides return to European action this week, with Leicester entertaining Porto and United welcoming a little-known quantity in Ukrainian top-flight side Zorya Luhansk to Old Trafford in the Europa League.
Manchester United 4-1 Leicester
Carrick looks to release Valencia down that right-hand flank but the linesman flags for offside. The final whistle sounds.
Herrera sports a bit of a limp after a late coming together with Amartey. United are just playing keep ball now as home supporters stream out of Old Trafford on all sides.
The away fans, to their credit, remain in fine voice despite a sobering afternoon.
Three minutes of added time signalled by the fourth official.
Mata looks to tee up Ibrahimovic for a fifth United goal, but Simpson does well to get across and block.
Mourinho's last available substitution sees Mata, still yet to complete 90 minutes under the new regime, make way for Ashley Young.
Rooney is barracked by the away supporters as he comes on for Rashford.
Zieler shows good hands to hold a hopeful drive from Ibrahimovic.
Ibrahimovic makes his presence felt in his own box by heading away a corner and diverting Drinkwater's subsequent shot wide. Blind clears the next delivery and United retain their three-goal advantage as we head into the final 10 minutes.
Valencia fires a cross towards Ibrahimovic that is too powerful for the Swede to contest.
At the other end, the confident Gray chances his arm with a daring effort from the left that is tipped over by De Gea.
Mourinho turns to his bench for the first time this afternoon, sending on Carrick for his 500th league appearance in place of Lingard.
The impressive Pogba does well to release Ibrahimovic, but he is quickly flagged for offside. Herrera then shoots over after Leicester fail to adequately clear Blind's corner.
Simpson is cautioned for bringing down Rashford.
Ranieri made his third and final change a few minutes ago, introducing Jeff Schlupp in place of Albrighton. The former United trialist almost latches on to a clever flick from Slimani, but De Gea is alert to gather.
He then pulls the ball back for fellow substitute King, who shoots tamely at the goalkeeper from a good position.
20 minutes remaining at Old Trafford.
United suddenly spark into the life as Lingard fires Herrera's cutback over the crossbar under pressure from Gray.
He then turns provider for Ibrahimovic, who sees a bending low shot tipped round the post by Zieler.
Not that it really matters too much in the grand scheme of things, but United are looking a little sluggish again here as we approach the hour mark.
Leicester, knowing that a second goal now might at least make Mourinho sweat a little, remain on the front foot and Fuchs sees a half-volley blocked.
It's extremely unlikely to spark any kind of incredible second-half comeback, but Leicester reduce the deficit courtesy of a smashing strike from substitute Gray.
The 20-year-old winger cuts inside from the left and shrugs off the attentions of Lingard before rifling an unstoppable right-footed effort past De Gea and into the top corner from 25 yards.
That was special.
Goal: Manchester United 4-1 Leicester (Demarai Gray)
Leicester welcome Portuguese giants FC Porto to the East Midlands on Tuesday evening, of course....
Albrighton gives the ball away in a dangerous area and Huth reacts well to just divert Pogba's cross away from the head of Ibrahimovic.
Unsurprisingly given that big lead, United appear content to hold possession here and invite Leicester to come and get the ball. Huth receives the first yellow card of the afternoon for a heavy late challenge on Pogba.
The second half is off and running. Two changes from Ranieri, who sends on Andy King and Demarai Gray. Mahrez and Vardy are the casualties of that first-half horror show.
While we wait for the second half to begin, here's more on Mourinho's decision to omit Rooney from his starting XI.
Crisis, what crisis?
United admittedly looked poor defensively in the early stages of this contest, but have since blitzed the beleaguered champions with four goals - three of which came in the space of just five minutes.
Three have also come from set-pieces, which will infuriate Ranieri given how well his side defended and indeed attacked such opportunities during their incredible title-winning campaign.
This match is already far beyond them and Leicester will need to make changes quickly to avoid further humiliation.
Manchester United 4-0 Leicester
Two minutes of added time to come at the end of this first half. Leicester are being quite simply hammered.
