A silly booking for David de Gea as the United keeper tries to run down the clock. Understandable at 1-0 but 3-0? 

Moments later Paul Pogba forces Kasper Schmeichel into a neat save. Leicester cannot wait for the final whistle.

Gray Jones: Give Ranieri the Sevilla games as a thank you for last season. He at least deserves that finale.

11 Jamen: Ranieri got Jose sacked last year by beating Jose. Jose is trying to return the favour.

Jay: Fluke or not - Ranieri won Leicester the title. The least he deserves is some loyalty and support from the club & 'fans'

Another delicious move by United. Antonio Valencia lays it on a plate for Henrikh Mkhitaryan but he lifts it high over the bar. Should have done better.

Ashley Young has come on for the closing stages in place of Marcus Rashford. 

A number of Leicester fan have seen enough. They're heading to the exits as United's fans chant "going down" in their direction.

Next three games for Leicester - Swansea, Liverpool and Hull. If they lose those, how can Ranieri keep his job?

It is a business. There is no room for sentiment. They are a team down on the slippery slope. You can see hope will Hull, Swansea and Sunderland.

Vital challenge by Christian Fuchs prevents Henrikh Mkhitaryan from making it four. It's only a matter of time. United are finishing strongly.

Mata has had a big influence on the game and scored a terrific third goal.

You could argue he was lucky to stay on the pitch for that reckless challenge.

Taz Bartowski: I do love Ranieri. We'll also probably name a street after him and erect a statue but...someone call Pearson for a third spell!

C Li: Ranieri never replaced Kante and is paying the price for it. It's easier to win the title than retain it.

Kyle: Absolute idiots those saying Ranieri should be sacked. People have such short memories. Ranieri will not be sacked. 

A roar goes up from Manchester United's travelling fans as Marouane Fellaini gets ready to come on. Juan Mata is the man to make way and he's getting a well deserved ovation from the fans in red.

Gerard Hennessy: Mr Ranieri really is a lovely man but I'm afraid last year really was just a very fortunate fluke. No way back now.

Leicester's next five Premier League games? Swansea (away), Liverpool (home), Hull (home), Arsenal (away), West Ham (away).

Is it conceivable for Ranieri to be sacked? They just don't look like scoring a goal. I think we will learn a lot when they play Swansea next.

This is a thoroughly professional job by United. They're doing the nasty jobs so well. Riyad Mahrez delivers another cross into the penalty area but Antonio Valencia is there to mop up and launch another swift attack. Too comfortable for the visitors.

Tom West: I love Ranieri, but we'll go down with him. Needed creative cm in the window. No clue who could come in, but change is needed.

It was this time last season that people started taking Leicester seriously after beating Manchester City 3-1 at the Etihad. How quickly things change. The Foxes are playing like a team heading for relegation.

Vardy is too isolated for Leicester. 

They have so many bodies behind the ball but it just keeps on coming back.

Incredible. A long ball is pumped into the Leicester area and everyone has stopped running.. except Juan Mata. It's not off side. Mata gets in a tangle and the chance is gone. 

An hour gone. Leicester, who have not scored a league goal for 490 minutes, have had one shot on target.

Paul Pogba is booked for a cynical challenge on Wilfred Ndidi 20 yards out. Pogba protests his innocence. Nice try. Up steps Riyad Mahrez. And that's close. Just wide.
