And that's it! Manchester United add another three points to their tally, which guarantees a seven-point lead in the Premier League going into 2013, with Manchester City having gone down 1-0 to Sunderland. It's a bitter pill for Newacastle to swallow though as they remain too close to the relegation zone for Alan Pardew's liking, although there were plenty of positives to take out of this one.
We're well over the four minutes of added time already, but Anita needs plenty of attention after been crumpled down following an awkward challenge in the midfielder. He looks in a bad way and needs to be stretchered off as Newcastle are forced to see out the rest of this game with 10-men.
That will be Javier Hernandez's last contribution for today as he's brought off for Darren Fletcher. Meanwhile, we're already three minutes into an added four, and as it stands Manchester United on heading towards three precious points.
Heartbreak for Newcastle as Manchester United steal the lead right on 90 minutes. Michael Carrick floats in a sublime ball which finds Javier Hernandez completely unmarked in front of goal, although the striker still has plenty to do to catch the ball on the volley, but he does it with some aplomb to nestle the ball in the back of the net.
GOAL! MAnchester United 4-3 Newcastle! Javier Hernandez!
Shola Ameobi is looking lively up front for the visitors, but he can't quite get the right connection from a cross and De Gea makes a comfortable save.
Point-blank save from Tim Krul now as Ryan Giggs hangs up a gorgeous ball for Javier Hernandez to attack, but his header is wonderfully kept out by the goalkeeper.
David de Gea can count himself very fortunate as Shola Ameobi's shot comes back off the base of the post and into the keeper's very grateful hands.
Robin van Persie curls this one into the far-post, but there's no-one in a red shirt there and the defence can watch the ball bounce out to safety.
Mike Williamson plays himself into trouble after dilly-dallying with his clearance, allowing Patrice Evra to nip in and win his side a free-kick near the corner flag. They play it short but to not too much effect, although they retain possession and eventually win another set-piece on the other side of the pitch.
We're less than 10 minutes away from the 90 now, although I'd rather this one didn't end as you just don't know what is going to happen next.
So close for the hosts now as Antonio Valencia delivers a peach of a ball into the area to perfectly pick out the unmarked Javier Hernandez, but the Mexico international can't direct his diving header and the ball flashes just the wrong side of the up-right.
That is quite brilliant from Robin van Persie as he breaks the off-side trap to run onto a clipped ball over the top, but his first-time hit on the half-volley bounces a fraction wide of the up-right. Would have been some goal to add to his already glamorous goal-scoring record.
Massive penalty appeals from the home side now as Javier Hernandez's shot strikes the arm of Fabricio Coloccini inside the area, but the referee is adamant in his denial of a spot-kick, although replays show Manchester United might have had a case there as the defender's arm was well away from his body at the time of contact.
A rare lull in play in the second-half now, but something tells me we aren't done with the goals just yet.
Dare to try predict the outcome of this one? Well, Sky Bet have Manchester United at 5/4 for the win, while Newcastle remain at 10/1 for the three points. A draw, meanwhile, is at 4/5, so good luck to you.
A change up front for Newcastle now as Shola Ameobi, match winner for the Magpies at the weekend, comes on for Demba Ba.
You just can't tell which way this game is going to go next, and the scores are now back level at 3-3. Tim Krul produces a stunning save to keep out Robnin van Persie's initial effort, but the striker eventually gets a second bite of the cherry and makes no mistake, slotting his effort into the bottom corner of the net.
GOAL! Manchester United 3-3 Newcastle! Robin van Persie!
A change for the hosts now, with Paul Scholes making way for Tom Cleverley.
This game is now officially a classic. The hosts lose possession to Gabriel Obertan, who breaks down the wing before playing a low ball into the area, where Papiss Cisse shows good awarness to run onto the ball and crack his first-time effort into the back of the net. No chance for the goalkeeper there as the ball had just been hit with too much venom.
GOAL! Manchester United 2-3 Newcastle! Papiss Cisse!
De Gea has to be quick to rush off his line to just get to the ball ahead of Demba Ba, who had been motoring down the pitch in an attempt to just get a foot in. Could have been dangerous there, but the keeper did really well.
First change of the afternoon now, with Newcastle manager Alan Pardew introducing former Manchester United midfielder Gabriel Obertan for the impressive Gael Bigirimana.
Robin van Persie produces a classic striker's tackle on Anita, hacking the player down from behind, but this time the referee keeps his card in his pocket, although it looked suspiciously deliberate from the Dutchman.
Danny Simpson is the latest player to be booked as he goes in very late on Jonny Evans, who flies into the advertising boards and remains down clutching his back. He's back on his feet now, but that's the sixth booking of the afternoon and both sides are in danger of going down to 10 men.
I guess I'll be eating my words now, cause Manchester United have just pulled themselves level. It was a bit of a soft one from Newcastle's perspective, with Patrice Evra's weak shot somehow catching Tim Krul unawares, with the goalkeeper unable to get a glove on the ball as it nestles in the bottom corner.
GOAL! Manchester United 2-2 Newcastle! Patrice Evra!
A very poor ball over the top from Jonny Evans runs right through to Tim Krul, bringing a roar of groans from the home fans and almost underlining the hosts' ineffectiveness so far.
Jack from Cambridge emails in: Fergie should be sent to the touchline for that sort of outburst. How disgraceful. Even if you dont agree with the decision, you dont do that, not setting an example to youngsters out there!
Appeals for a penalty from the home side now as Javier Hernandez goes down inside the area following a collision with Fabricio Coloccini, but the referee is probably correct to wave away the calls for a spot-kick as they Red Devils striker went down far too easily. No booking for simulation though.
Antonio Valencia is the latest to be show a yellow card as he goes right through Danny Simpson in what was a very late challenge.
A bit of a scrappy start to the second-half here as the ball is becoming bogged down in the middle of the park. Papiss Cisse tries to change all that by towering above the defence to get his head on Demba Ba's cross, but the Senegal international can't keep his effort down and the ball sails well over.
Javier Hernandez gets in behind the defence before racing through on goal, but his run is brought to a premature end as the linesman's flag goes up for off-side.
And we're back up and running for the second-half. Sir Alex Ferguson was having a real go at the match officials before the restart, presumably over Newcastle's controversial second, which at the moment is deciding this match.
Chris Walters has been none-too-impressed with Manchester United today, writing in: My strict rule is that, from the moment Paul Scholes comes on I turn off a match. Invariably, these days, his presence heralds a game in which United will struggle, make stupid errors, and be absolutely painful to watch. Even if he's not directly involved in the errors, Scholes being there signals that United will play badly. As I check the ticker every few minutes I see that my rule is a good one, and I'm much better off watching Dr. Who reruns.
The referee's whistle brings the first 45 minutes to a halt, with Newcastle heading down the tunnel with a 2-1 lead. History in the making for the Magpies, while Manchester United will need to tighten up in all areas of the field if they are to rescue the game this afternoon. Join me after the break to find out how this one finishes.
The fourth official shows there will be two minutes of time added on here at the end of a very entertaining first-half.
Can Manchester United battle back again? They're now odds-against to win at 5/4 with Newcastle 2/1 to hold on for victory.
It's not the best free-kick from Robin van PErsie though as he fires the ball well over the bar.
Yellow cards coming thick and fast now as Mike Williamson is the latest to be booked for bringing down Ryan Giggs right on the edge of the area.
Really good move from the Red Devils now as Van Persie's flick tees up Hernandez on the area, but instead of going for goal the striker tries to swing one over for Valencia, but he gets his delivery all wrong and the ball fizzes out fort a goal-kick.
Javier Hernandez goes into the referee's book now as he clips the heels of Cisse who was breaking clean through on goal. They almost make the most of the set-piece, but Sylvain Marveaux's sees his curling effort crash off the woodwork with De Gea well beaten.
Decent chance for the hosts as a ball is swung over the top for Patrice Evra, but the full-back was in an off-side position, although his attempted header back into the mix was straight to Krul anyway.
Jonny Evans now also becomes the first player to be booked for a sloppy four close the area. The resulting free-kick is not a very good one though and the defence easily heads clear.
Controversy at Old Trafford! Danny Simpson's hopeful shot is deflected into the back of the net by Jonny Evans, but the linesman's flag goes up after Demba Ba had strayed into an off-side position. However, after a lengthy debate between the match officials the goal is awarded as the Newcastle man had not actually interfered with play, leaving the home team furious with the referee. It was probably the right decision though, but that doesn't make it an easier pill to swallow for the hosts.
GOAL! Manchester United 1-2 Newcastle! Jonny Evans own-goal!
Calls for a penalty from the home fans as Patrice Evra goes down inside the area following a goes shoulder-to-shoulder with Davide Santon, but the referee rightly waves away any appeals.
It's all level at Old Trafford, and it's a tap-in for Jonny Evans as Tim Krul could only turn the ball into the midfielder's path following a close-range shot from Javier Hernandez.
GOAL! Mancehster United 1-1 Newcastle! Jonny Evans!
Will it be yet another comeback win for Manchester United? They're still favourites to pick up the points at 4/6 with Newcastle 7/2, having started the match as 10/1 outsiders.
Dangerous delivery from Ryan Giggs now as he curls in a sumptuous ball, but the Newcastle defence are on top of it and manage to head clear. Sustained possession for the Red Devils, although Demba Ba does well to win the ball before breaking up field, but Papiss Cisse doesn't seem to be on the same wavelength as his team-mate and makes a run this way when Ba had passed that way.
United have enjoyed the lion's share of possession so far, although they are yet to even test Tim Krul, whose only job so far has been to take goal-kicks.
A free-kick for United now as Williamson leads with his elbow in an aerial challenge, although United play the set-piece backwards and all the way to De Gea.
Demba Ba breaks down the wing before cutting inside Ferdinand and working himself a shooting opportunity, but he doesn't quite get the right connection and the ball is blocked on the edge of the area.
A bit of a trademark challenge from Paul Scholes as the Englishman gets all of the man and none of the ball. It's only a free-kick though, although it takes a decent block from Rio Ferdinand to prevent the ball from threatening goal.
Valencia gets a talking to from the referee now for a very cynical challenge in the middle of the park, and he might already be one more bad challenge away from a booking.
Brilliant stuff from Ryan Giggs as he clips a lofted pass over the top of the defence, but there's just too much pace on the ball and Antonio Valencia is unable to keep the ball in play. He had three team-mates waiting unmarked in the area, and Newcastle can consider themselves lucky that move did not develop into a goal.
Chris Walters adds: I was excited for this match until I saw Carrick, Scholes, AND Giggs starting. I won't be watching now. It will be painful as Giggs tries to play like he's still the fastest player on the pitch, and has the ball taken away, Carrick gets anxious at the men on either side of him, and Scholes gets angrier until he violates someone's human rights. This may be the day Newcastle finally win at Old Trafford.
Amanda Cunningham says: Cant believe Utd let in another early goal! Come on Fergie, sort it out! Still think MANU will win when they get going. Michael Carrick, my Man Utd hero, will score a goal to win it for us. Come on you devils!
United launch into a counter-attack as Javier Hernandez makes a brilliant run down the wing before putting in a really dangerous delivery, but there's no-one there in a Manchester shirt and the defence can watch the ball go out for a goal-kick.
More attacking intent from the visitors now as they work their way into the opposition area, but Vurnon Anita tries to do too much and is eventually robbed of the ball.
That goal will come as a massive boost to the Magpies who have not won at Old Trafford since 1972. Records are made to be broken though.
It's a gift of a goal from United as Michael Carrick surrenders possession at the back to allow Demba Ba to to run through on goal and shoot, and although David De Gea is able to save, the goalkeeper only parries the ball into the path of James Perch who has the simple task of tapping home.
GOAL! Manchester United 0-1 Newcastle! James Perch!
Robin van Persie looks to switch one over for Antonio Valencia, but it's a rare miss-hit from the Dutchman as his delivery bounces harmlessly out for a goal-kick.
It's looking tidy from Newcastle in the opening stages as they look to keep hold of the ball, but they eventually concede possession as United break, although Michael Carrick's attempted through ball is vitally intercepted in the Magpies area.
And we're under way!
And here come the players out into a very wet Manchester afternoon, with the pre-match formalities already under way and the kick-off imminent.
James Wallbridge writes in: Glad to see pardew dropping gutierrez. rooney and young will be big misses for man united. But i still don't think we should take any chances by flooding men forward, because man u are clinical when they counter. Marveaux should bring some pace on the counter, i'd be pleased to see 9 men behind the ball with marveaux ready for US to counter man u. and i'm sure obertan will be ready to show what he can do. I'm going for a 0-0 draw. But i do reckon the toon might be able to pull off an incredible result. COME ON TOON ARMY!!!
We're around 10 minutes away from the kick-off now, with referee Mike Dean about ready to lead the two sets of players out into the Theatre of Dreams.
We've got our first caller of the day, with Marcus emailing in: After the swansea game we need a win today. A good side united have put out but no rooney is a surprise. However don't think we will win, 2-2 draw.
Newcastle are without Cheik Tiote who is suspended, meaning 19-year-old Burundi midfielder Gael Bigirimana will get his chance to impress from the start. Hatem Ben Arfa (hamstring), Steven Taylor (hamstring), Yohan Cabaye (groin) and Ryan Taylor (knee) are all out through injury.
So, no Wayne Rooney for United today as he, along with Ashley Young, reportedly picked up injuries during a Christmas day training session Carrington, while Danny Welbeck is missing through illness. That means Javier Hernandez partners Robin van Persie up front, while veterans Paul Scholes and Ryan Giggs marshal the midfield.
Man Utd: De Gea, Smalling, Ferdinand, Evans, Evra, Valencia, Carrick, Scholes, Giggs, van Persie, Hernandez Subs: Lindegaard, Vidic, Cleverley, Fletcher, Buttner, Wootton, Tunnicliffe
Newcastle: Krul, Simpson, Williamson, Coloccini, Santon, Anita, Perch, Bigirimana, Cisse, Ba, Marveaux Subs: Elliot, Shola Ameobi, Obertan, Sammy Ameobi, Ferguson, Tavernier, Campbell
As promised, the teams...
The team sheets have just come across my desk, but before we get into that why not take the chance to get involved by emailing any and all thoughts or predictions to firstname.lastname@example.org.
Plenty at stake then today, but how about making it a little bit more interesting by popping over to our friends at Sky Bet, who have United at 2/9 for the win, while Newcastle are a bit of a long-shot at 10/1.
Newcastle, meanwhile, earned three very important points as they brought an end to their three-game losing streak by snatching a 1-0 victory over QPR on Saturday, Shola Ameobi scoring his third goal of the season to wrap up the win. However, there's still plenty of work to do for Alan Pardew's men, who sit 14th in the standings, five points above the relegation zone.
It's looking to be a very happy New Year for the Red Devils, who top the standings by four points with just two rounds of fixtures remaining in 2012. Sir Alex Ferguson will be looking for an improved performance from his side this afternoon though, having seen them held to a 1-1 draw against Swansea City at the weekend.
Good afternoon ladies and gentlemen, merry Christmas, happy Boxing Day, season's greetings and Yuletide cheer to all. With severely overstuffed stomachs and perhaps the fuzzy memories of one too many, there couldn't be a better way to spend the day than with 90 minutes of Premier League football. I'm Ryan Gordon and I'll be taking you through all the action as Manchester United host Newcastle at Old Trafford. Kick-off is at 15:00 GMT.
