Sub Sanchez struck winner with late header
Man Utd had gone four matches without a win
Newcastle remain without a win all season
Magpies had led 2-0 at the break - increasing pressure on Mourinho
Juan Mata
Hello!
Juan Mata checks for a pulse, gets out the defibrillator and shouts 'Clear!'
A shock to restart Manchester United? A great free-kick is what it is, left-footed, over the wall and into the top corner.

There's only one man who can save them... Break out the waistcoat!
Lois: Am i the only one that's thinking we could do with Gareth Southgate.. we need organisation.. team work.. pride in wearing the shirt.. we need to be united.. something we currently are not!
Mike: Manchester United should just bring the reserves to play this match!
Man Utd 0-2 Newcastle
There is still a quarter of this game left, all sorts of time. And now Manchester United win a free-kick right on the edge of the area.
Chance?

Kenedy, scorer of the first Newcastle goal, is off. With a limp too. On comes Jacob Murphy.

Manchester United's front three have been disappointing. Anthony Martial, Marcus Rashford and Romelu Lukaku haven't been in the game.

David de Gea claims a cross from in front of Nemanja Matic. This Manchester United formation is like a cheese dream.
Alexis Sanchez is on for Marcus Rashford. Could be playing in goal for all I know any more.

Some lost faces picked out in the crowd as Alexis Sanchez strips off ready to come on. No pressure...
Man Utd 0-2 Newcastle
Ouch - Paul Pogba trips up DeAndre Yedlin as he moved into space on the break and it's a booking. Cynical challenge.

Jose Mourinho was urging his players forward just then, kicking every ball.
But when Marcus Rashford's knock back bounced straight through to Martin Dubravka, the Manchester United manager turned and offered a sad little shrug.
His team seem to be running out of ideas.
Man Utd 0-2 Newcastle
Into the last half hour. Mike Ashley is in the stands and looks on, tense. Enjoy this Mike! It won't get any better than this for you at a Newcastle game.

They've been better in the second half but they still trail, Matic should have scored, Rashford's just missed a header.
Mourinho is much more animated on the sidelines waving his arms about and shouting at the players, Newcastle aren't lying down easy though.

Chris Smalling is all over the place. He just keeps giving it away. Kenedy just went for too much power but it was always rising over the top. Another chance for the visitors.
Man Utd 0-2 Newcastle
Newcastle are desperate for these three points and it shows, they look edgy out there.
But then they have a big chance, Chris Smalling's header is seized on by Kenedy, he has a four on three overload but shoots and fires over the bar!

Sean: Players turned against Moyes, then Van Gaal and now Mourinho. Something wrong with United culture.
Pulkit: The only ones doing their job in the whole Manchester United set up are the Fans at Old Trafford. What a support!!!

Marcus Rashford has had two good opportunities with headers but he hasn't hit the target with either of them.
Man Utd 0-2 Newcastle
This has been a good team talk from Jose Mourinho. His side are well on top now. Paul Pogba, suddenly popping up on the right wing and flicking in a good cross which Marcus Rashford can only head wide.
Man Utd 0-2 Newcastle
Newcastle are just camped in, as Juan Mata volleys wide from 20 yards.
Manchester United are pushing hard for a goal and the roof may come off OT if they get one. All is not lost for Jose Mourinho just yet.
Man Utd 0-2 Newcastle
Got to hit the target!
Paul Pogba has a shot from 20 yards, it's deflected and Martin Dubravka makes a handy save, but it only coughs up a chance for Nemanja Matic.
He leans back and spanners it over from eight yards. I mean a total loss of technique...

The Theatre of Nightmares...
Chris: Man Utd playing like a team who know the boss won’t be at training on Monday?
Tommy: Not sure how people can criticise the players and defend Jose. It all stems from him.
Richard: Our back 3 is Pogba, Matic and Smalling. What is happening?
Man Utd 0-2 Newcastle
Chance - Juan Mata finds Marcus Rashford who turns away from one man but then is hesitant and he is tackled well by Federico Fernandez.
That's got the Stretford End going though - and now the hosts win a corner...
