That's half-time and a wrap from us in this page.
Follow the second half here and see if Chelsea can fight back.
Lee on the text: Imagine if Diego Costa was playing today. With him and Mitrovic they would had have to have put boxing ring style ropes around the pitch.
Ashwin in London: Sincerely hope the Tyneside clubs get relegated this season, permanent passengers in the PL. Ashwin, London
Southampton fans seem surprised but pleased with their victory over Swansea.....
Ashley Drouet on Facebook: Wasn't quite expecting it to be so comfortable today. Whether that says more about us or Swansea I'm not sure, but it was a very good performance and a much needed 3 points.
Patrick Parnaby: Sadio was the Mane man today
Lisa in London on text: Fabregas keeps getting caught in possession- seems to have mislaid his magic hat so far this season. Hope he finds it soon!
Luke in Somerset: Matic is being bullied in the middle of the park by Perez, a man who is half his size...
Chelsea fans - are you worried?
Schoolboy defending from Chelsea but a fine finish from Ayoze Perez. Kurt Zouma and Branislav Ivanovic neglect to head clear a cross from the right and Perez brings the ball down to finish off the post. Boom.
Alfie Snow on Twitter: Wouldn't be surprised at another Chelsea loss, Newcastle will always be our bogey team!
Rob Millward: The worst ive seen us play in years... No fight no pace no nothing at the moment... We're been outplayed by NEWCASTLE!
It's not often you get a good honest managerial quote.
"I'm always sad when one of my players gets injured and even more when it's Messi," said Barcelona manager Luis Enrique after Messi was ruled out for two months.
"But we need to accept the challenge and understand that this is part of football and get through it. We will not change our style of play without Messi, although there are many moments in games in which Messi liberates us and finds solutions for us, so we'll have to strengthen in other areas and the team will have to step up without him."
Rijaz on Twitter: If Spurs score four, it's sure that Arsenal want to score five somehow.
Paul Hallett: Big Manchester United fan, not used to seeing us play like this, nor do I like it, but I can see it appears to be working. Nice to be top.
When you concede with a minute to go, it is always disappointing but we will take encouragement from how well we played. We went for the winner and Nathan popped up but unfortunately we concede and it is not nice. I thought Nathan could have an impact on the game and we dominated the middle. The two team both went at it and tried to win the game and did well. I am pleased with the run but we had three points in our hands today. We have to do enough to get the points on the board.
Newcastle are a totally different side. They've had a fine spell of pressure and force Asmir Begovic into a pair of saves. First Ayoze Perez is on target, and then Daryl Janmaat has a go.
Luke Barnard: In a weekend for ending goal droughts, what a time it would be for Begovic to end his! Two years since his last against Southampton!
DJ Gallagher: Two English players out of 22 in Newcastle vs Chelsea lineups. There's the problem in English football

Stoke manager Mark Hughes: "It was an important win - we probably played better in other games and got beaten, this was about getting the three points. We played with a bit of apprehension in the second half which allowed them back into the game, but showed good courage after that as it would have been very easy for Bournemouth to gain momentum after their equaliser but we didn't allow that. Great ball by Glen Johnson for the goal, great finish by Mame Diouf." (On Xherdan Shaqiri, who went off injured in first-half stoppage time) "I haven't had an update yet - it looked like a hamstring so we'll settle him down tomorrow, have a scan on Monday and see what the damage is. He walked off so hopefully it isn't too bad."
So Manchester United are top of the Premier League....
Luke Richardson on Facebook: This so called 'philosophy' looks like it's coming together.. 1 or 2 players still needed I reckon.
Martin Savigar: Tough next four games for united next though.
Can United stay top of the table?
I am happy that we showed the character at the end and we deserved it. A draw is a fair result and they are probably gutted because of the timing of the last goal. All the teams we have played at home, apart from Newcastle, are all very energetic teams. They enjoy defending. If you match them in the awareness and the basics, then we are better than them on the pitch. If you drop yourselves, five or 10 percent, they use it and play well. We know what Andy Carroll brings us. He needs a few games to get to his best and was out for a long time. He is useful. It is not hard, but almost impossible to defend against him sometimes.
Liverpool boss Brendan Rodgers told BBC Sport: "Our only disappointment today was the two sloppy goals we conceded, both down to mistakes. Thankfully today the two Daniels up front were outstanding. Sturridge showed what we missed for over a year – he makes the difference and helps you compete. His finishes were brilliant. He’s nowhere near 100% fit yet. There was a couple of moments when he’d be away at his best but wasn't today. His two goals were the difference.
"There’s a hysteria around the club. However criticism comes, whether deserved or undeserved, you don’t like it. What has surprised me with it is we’ve lost fewer games than Manchester City, Chelsea and Arsenal in all competitions. We’ve only lost two. There’s scrutiny on the players but it’s made us stronger. We know we have some top players to come back in. The players gave everything, I am proud of them. We looked creative and dynamic today."

Can Manchester United win the league? Who is going down?
Adam Toth on Facebook: Finally Leicester have been bought down a peg. And it's great to see Alexis getting back to his best.
Alan Tate: If Manchester United keep improving, there will be no catching them.
Murray Young: Premier League standard getting poorer each season, Barcelona and Real Madrid are light years ahead for some reason or another.
Do Manchester United deserve some credit?
Bitty, scrappy start to the game in Newcastle where champions Chelsea are yet to get going. As you'd expect, a nervy atmosphere inside the ground as Loic Remy pokes one wide...
Shane Daly on Twitter: All Manchester United have to do now is win the next 31 league games & they are champions again, simple.
Jack: Don't see how people can say united have been awful, you don't need to win every game 5-0 to be champions

We have not been up to scratch in the last two away games. We were not focused enough and possibly made too many mistakes today. They punished us and we never recovered from that. All three goals were disappointing. It was poor decision-making and individual errors. It's not good enough for the standard we have set here at the club. We pushed to try to get back. We got the goal then had a couple of chances to make it 3-2. It's difficult to assess straight after the game what went wrong.
Really, really bad news for Callum Wilson and Bournemouth. How's your luck? That's three serious knee injuries before the end of September.
Bournemouth boss Eddie Howe: (On the Wilson injury) "It doesn't look good. He's in a brace, he's on crutches and he's in a lot of pain. It looks like it could be another serious knee injury. He took a whack to the knee, thought he was OK to carry on but then collapsed. It's a huge blow.
"I was disappointed with the first half, we didn't react well to Callum's departure but thought we were dominant with the ball in the second half, and at 1-1 there was only going to be one winner, so it's disappointing to have lost from there. We could have defended that situation better."
Adam in Edinburgh on text: How poor must the league be if this Manchester United team is top? The European competitions will remind us how far the Premier League has fallen since the 2005-10 period.
Christian in Tunbridge Wells: The bottom three clubs have been fighting relegation for years now. It's time for those three clubs to see what the Championship has to offer them.
It was not a very good performance today. The way we played is not the level we expect. But much more now today than normally we were clinical. That was the difference between Swansea and Southampton. You need good communication in the team but we had some problems - they were allowed four or five good shots from outside the area. At 3-0 up we should have dominated more in the last 30 minutes. We were too much in mind to defend the result rather than go and score more. I like to win and play good football.
Almost game time in Newcastle - you can follow blow-by-blow updates on that one in this page here, while we bring you the best bits accompanied by manager and player reaction from the rest of the day's games in this page.
Liverpool midfielder Lucas Leiva, speaking to Match of the Day about under-fire Reds boss Brendan Rodgers: "We wanted to win for the manager. We know what has been said about him and think we showed we are a group of players behind him and trying to make everything right. We know the pressure is on him but we wanted to play the way he wants us to play and I think we did that."
In League Two, Leyton Orient earned a point at Northampton thanks to a Dean Cox goal in the seventh minute of injury-time, but it failed to prevent them losing top spot to Portsmouth, who won 2-1 at Bristol Rovers. Wycombe moved second, with a 2-0 victory at Exeter. Newport earned their first league win of the season, 1-0 at Carlisle, who were brought back down to earth after taking Liverpool to penalties in the Capital One Cup in midweek.
The perennially unhappy-looking Jose Mourinho has a wonder down to the end of the tunnel at St James' Park ahead of the day's late game.
He looks seriously cheesed off.
Manchester United manager Louis van Gaal: "It's a nice feeling to be top of the table, it's the first time in my period so I'm happy. It's always difficult when you play against a team who is only defending and counting on the counter-attack. You have to be aware and I have to admit my defence was very good today.
"I was very happy with the goal in extra-time because they punished themselves. They were always wasting time and the referee was not reacting to that.
"A goal is the biggest influence in a game and I changed my approach at half-time because of that. It became another game but they didn't come at us very much."
Matthew on Twitter: LvG knows what he is doing? For £250m+ he should be top of the league!! 3-0 over this awful Sunderland side is a poor result.
Robert Espie: So much saltiness towards United. More points than any other team right now. Just fact.
So were United good today?
Leicester boss Claudio Ranieri: "It was difficult at the beginning and difficult at the end. We touched the post twice and that was our best moment.
"Arsenal are dangerous on the counter attack. In the first half was good and open but at 3-1 it was difficult.
"We shoot at goal at lot of times but Petr Cech is Petr Cech. I hope if we could hold at 2-1 we could force it until late in the game but Alexis Sanchez scored early. The second half was then finished. We must begin again now and repeat this start to the season.
"We must show character in the next match."
Peter Collins on Twitter: The only surprise from Sunderland is that they've actually made it to two points! Can they reclaim their record from Derby?
Dave Mangan: When will Tim Sherwood accept we need to go at teams to compete? Two games defence cost us, and attacking won one and was close again today.
Sunderland manager Dick Advocaat: "The first half we did well, organisation wise, but the problem was they scored one minute before half-time and one minute after half-time. United were the better side but they didn't create a lot of chances. It's a shame we gave that goal away in the first half because it made things different in the second half."
Rezaa: Arsenal need a striker, they said. Scoring five goals away from home against the only unbeaten side? Think again....
James Graham: Manchester United were fantastic. Patient and composed, Smalling was brilliant. It may be a different style, but it's the future.
Aston Villa boss Tim Sherwood: "We can't score two away from home and lose - it happened against Leicester as well. You score twice at Anfield and you expect to leave with something. I've told the boys their goals were avoidable and we have to tighten up - Liverpool did not have to work too hard to get them, and we have to put that right."
On Villa's poor start that has seen them drop into the bottom three: "Our performances have merited better than one win in seven games but I said from the start it would be an uphill struggle. We need to stay in the division and, if we do, we will be stronger next year."
What a job Jimmy Floyd Hasselbaink is doing...
Burton stretched their lead at the top of League One to three points thanks to a 94th-minute winner from Jerome Binnom-Williams, as they came from behind to win 2-1 at Chesterfield. Walsall were held 1-1 at home to Crewe, and Gillingham went down 2-0 at Barnsley. Sheffield United climbed into the top six with a 3-1 derby victory at home to Doncaster, who had defender Gary Mackenzie sent off. Shrewsbury were the only winners in the bottom 10, beating Blackpool, who stay bottom, 2-0.
Tom in Rugby: There's a funny smell coming from Sunderland. Smells like...capitulation...again.
Matt from Monmouth: It seems to me that any team that needs a pick me up, Villa are there to provide the medicine.
Even a win would not be enough to lift Newcastle out of the bottom three this evening, while Chelsea can jump from 16th to eighth win three points.
