United move on to another big game on Sunday - a trip to face Liverpool, who have won both of their opening Premier League fixtures 1-0. As for Chelsea, they go to Prague to take on Bayern Munich for the UEFA Super Cup on Friday. Their next league game isn't until September 14th, when they're away to Everton.
So Wayne Rooney turned in an all-action display for Manchester United, but Chelsea defended resolutely and the game ended goalless. The Blues move a point clear of Liverpool at the top of the early table having played three games, while United rise to fourth.
A glimpse of goal for United. Van Persie slams a volley into the body of Mikel and appeals for a penalty, but Atkinson isn't moved.
Chelsea have won their first corner after a slight mix-up between De Gea and Vidic. United struggle to clear the ball until Rooney tackles Ramires - for which he receives a round of applause.
Rooney's cross-field pass to Young wide right is a peach, and sets up two deliveries - the first headed back to Young by Terry, but the second causing Chelsea real problems and Cech has to bat the ball away.
Evra heads away Lampard's left-wing cross, and then Ashley Cole goes down in the area claiming he's been pulled by Phil Jones. Referee Atkinson says 'no penalty'.
Chelsea are 4/1 with Sky Bet to win this in the live in-play betting market. United are 9/4, and the draw is 4/5.
Midway through the 2nd half, Rohaan Mohanty emails in to say: 'Can Torres prove it to Mourinho that he is a big match player and score against United?'
Cole blocks Valencia's right-wing cross. Seconds earlier, Torres had galloped into the United penalty area but his run was blocked by Vidic.
A big handball shout for United and their fans, but referee Atkinson says no. Cleverley acrobatically shot into Lampard, who turned his body.
Cleverley blocks De Bruyne's shot and then the ball falls nicely for Cahill to strike a true shot from distance, but De Gea saves.
Burst of pace from Valencia takes him round Cole and away down the right but the pass is intercepted by Terry.
Slips from De Bruyne, Ramires and then Terry benefit United as the ball is fed from left to right with Rooney slipping in Welbeck. But his shot from inside the area is hugely disappointing.
Carrick's diagonal ball wide left finds Welbeck in space. The England forward dashes infield and tries an ambitious shot which is well wide.
Oscar is penalised for a high boot on Welbeck right in front of Mourinho, who is animated to say the least.
Van Persie backs into Terry on the right side of the area, the Chelsea defender doing enough to put the Dutchman off. Then Terry clears as Welbeck attacks down the left channel.
Cahill's header from Evra's cross finds Valencia in space, but United can't make anything of the opening. Chelsea break but are thwarted 30 yards from goal.
Time for some Blues opinions. First up, it's Ryan on email: 'I still think that Chelsea need a striker on the pitch. And to fit the playing style of us, and the opposition, I have to say that it's got to be Ba. I hate to say it... ' On Twitter, @charliehardma and @Awabomar both want to see Torres come on.
Some views from Twitter on Martin Atkinson's officiating. @JoseffJBSmith says: 'I think the ref is letting the players engage in physical play. It hasn't gotten out of control...yet.' Meanwhile, @jlewis_design wants to know: 'Why no yellow for Valencia's challenge? Then they give De Bruyne a yellow for not so harsh tackle! Shocking decision.'
United fan Barry from South Carolina emails in with some advice for David Moyes: 'We need to take off Welbeck and Valencia and put on Anderson and Kagawa. Put Kagawa in the hole behind Rooney and Van Persie and have a central three of Carrick, Cleverley and Anderson. Wish we had Zaha and Januzaj on the bench.'
So, it's still all square. Some interesting refereeing in there, and that for me might be the biggest talking point of the first half. What did you make of that opening 45 minutes? Let me know. Email me at firstname.lastname@example.org or tweet me at @jonboy79.
Phil Jones is still limping after that earlier fall - he might not re-appear for the second half at this rate.
De Gea has to save from Oscar again, a low shot from a central position outside the box. Hazard had set up the chance after De Bruyne's pass forward found him.
Van Persie almost gets to the ball in the box after a cleverly-worked move instigated by Rooney. Intelligent play from United.
Phil Jones is holding the small of his back after landing awkwardly from a leap to win a header above Ashley Cole. He's soon back on his feet though, and his low right-wing cross is toed away by Terry into the path of Cleverley, who shoots from 20 yards - but it's always rising.
Ferdinand swings in another deep cross and Terry is briefly grounded after heading clear under pressure from Valencia.
Hazard does brilliantly to race back and dispossess Valencia, who had danced around three Chelsea players on the right wing.
And De Bruyne becomes the first player booked as he tangles with Van Persie on the touchline. The Belgian comes off far worse though, and is left with a bloody lip.
More leniency from Atkinson - this time, Valencia gets a stern talking-to but no more after a late slide tackle on Oscar near the halfway line.
Cleverley's skip and pass allows Rooney to turn away from Ramires and Cahill on the edge of the box - but his low shot is tame and easy for Cech to claim.
Darryl from Blackburn emails in to say: 'Chelsea clearly missing someone to hold it up. So many balls going forward and into space where no one is. I think Torres would make a big difference.'
Ivanovic has to head away Valencia's right-wing delivery as van Persie was lurking at the far post. Chelsea defend the corner and try to counter.
Evra loops in a cross from the left and van Persie gets his head to it, but he couldn't get any real control or power.
After Carrick closes down Ramires, van Persie gets the ball just outside the box and chooses to take it round Ivanovic and let fly with a fierce left-foot shot that hits the side-netting. Close.
Oscar's shot goes well wide and it's not even a corner. Replays suggest it might have grazed Phil Jones' knee, however.
Stylish footwork from van Persie, who pirouettes towards the area from the left wing. Chelsea prevent him or Rooney from entering the box, however.
Vidic heads Oscar's cross right back to him, and then Ivanovic fires over from long range. United have had 57% of possession so far.
Now Cole escapes a booking for a tackle from behind on van Persie. The Chelsea defender looked a little fortunate to get away with that one. Lenient start from referee Atkinson.
Some appeals for handball against Ashley Cole outside the box, but the officials let play continue as Chelsea move away from their own area.
Ivanovic takes decisive action in the box and slides to clear the ball as United looked to work it into the Chelsea area. Terry heads the corner away.
First real chance - De Gea has to shuffle a little to his left to save Oscar's snapshot. Neither Vidic or Ferdinand could get enough clearance on their headers.
Great link-up play between Welbeck and Rooney in central midfield - Ramires was struggling to get near them.
Chants of 'Rooney, Rooney!' from BOTH sets of supporters whenever the United forward gets on the ball, reports Sky Sports' Geoff Shreeves from the touchline. A little message from the Chelsea fans, while the scoreline is still 0-0?
Rooney pressurises Ashley Cole in the left-back position and then jumps into the back of John Terry, giving away a foul.
Cahill has to turn on the pace to track the approaching run of Rooney, who is fed accurately by Valencia wide right.
Welbeck tracks back and wins the ball from Oscar. A sloppy pass from Cleverley allows Chelsea to regain possession, however.
Schurrle is playing in an advanced centre-forward role for Chelsea. United moving the ball around well in the early stages.
From the @ManUtd Twitter account: 'Tonight, Old Trafford honours the lives of Jack Crompton, Brian Greenhoff and Ron Davies with a minute's applause.' The legends warmly remembered...
One last bit of feedback before kick-off, from Chris Green on email: 'I'm mighty relieved to have found out that Rooney is in the starting line-up for this evening's match - if he had been left on the bench, I think he could have been heading for the United exit door, but because he's starting, I think Chelsea's hopes of signing him are definitely over.'
And one more fact from our very own @SkySportsStatto on Twitter: 'David Moyes has never won in 8 meetings with Jose Mourinho (all with Everton against Chelsea - D3, L5).' The teams are now on their way out!
A couple of interesting stats for you ahead of kick-off, courtesy of Opta: 1. Manchester United have suffered 14 Premier League defeats against Chelsea; more than against any other side. 2. A win in this game will ensure Chelsea have won their opening three league games in four of the last five seasons.
A good point on email from Akogwu Austine: 'Good line-up by Jose Mourinho, but he should beware it could backfire as Di Matteo's against Juventus.' That match he's referring to is the 3-0 defeat at Juve last November that cost RDM his job - he didn't choose an out-and-out striker either, going for Mata, Hazard and Oscar in attack. But Akogwu adds: 'Even at that, I reckon 3-0 Chelsea win!'
That brings us on nicely to the match betting. A lot of you are getting involved in Sky Bet's tempting 11/2 boosted odds for Robin van Persie to score the first goal. Anything else caught your eye? Let me know. As for the straightforward stuff, United are 13/10, Chelsea are 9/4 and the draw is 23/10.
As for those of you backing the hosts, @teazle007 on Twitter says: 'I am predicting a win for Man U! Chelsea midfield does not look strong enough.' Meanwhile, on email, James Cutting is very specific and writes: 'Seeing as Rooney is starting, I'm going for Rooney score first and United win 3-2 @ 250/1.'
Time for some more of your predictions. First up is @axionazure on Twitter from Brazil: 'Dangerous long range finishers in De Bruyne and Schurrle. I put my money on a dramatic 2-1 late winner for the Blues.' Ryan Webster on email has gone for the same scoreline but adds: 'I think that they should have Lukaku up front because he was electric at the last match of the season for WBA when he got a hat-trick against Man Utd.'
David Moyes shares a few words with Sky Sports' Geoff Shreeves before kick-off. When asked if he needed to have any words with Wayne Rooney (who starts against the club who has twice bid for him this summer), Moyes said: 'It never crossed my mind. I just got on with it. He's a Manchester United player - and he'll prove that tonight.'
Jose Mourinho has been talking to the Monday Night Football team. When asked to explain his team selection, he replied: 'I can't - David is in his room listening!' However, he then continued by saying: 'I go for mobility. I want to try to win. I select no target-man, but four attacking players.'
Jeremiah I on email thinks he knows why Mourinho has left out his centre-forwards: 'Don't like what Jose is doing here with this team - clearly playing with no strikers as a statement to Rooney to come and fill the void!'
It's not so much the inclusion of Wayne Rooney as the team selection of Mourinho that's got you all talking. What does the next week hold for Chelsea strikers Fernando Torres, Romelu Lukaku and particularly Demba Ba? We're yet to learn why Ba's not involved tonight. And with Juan Mata being benched for such a big game too, that will probably revive talk of his potential exit.
Ben Gleeson is watching in Cardiff and he's emailed in to say: 'The main thing that stands out to me is how slow the Chelsea back four looks without David Luiz or Azpilicueta. Yes, Ivanovic, Cahill and Terry are brilliant defenders but they can all be turned by a quick player like Welbeck or Valencia. Chelsea might be caused some problems there. The front four of Chelsea really excites me though, I hope the lack of playing time together won't cause them to seem disjointed.' Ben's predicting a 2-1 home win - anyone agree with him?
Reaction is coming in from you now on the somewhat surprising team news. Liam Mortell on email says: 'I don't like to see Mata on the bench - but Chelsea have the skill and ability to win.'
First tweet of the night from @MattydBWFC: 'Neutral supporter! However I think Chelsea will steal this 1-0. Looks like a defensive line-up, I can see them hitting on the break.'
And Chelsea: Cech, Ivanovic, Cahill, Terry, Cole, Ramires, Lampard, De Bruyne, Oscar, Hazard, Schurrle.
Here are the starting line-ups in full. First, Manchester United: De Gea, Jones, Ferdinand, Vidic, Evra, Carrick, Cleverley, Valencia, Rooney, Welbeck, Van Persie.
As for Chelsea, Jose Mourinho has decided to name a starting XI with no recognised striker. Kevin De Bruyne and Andre Schurrle come in following the 2-1 home win over Aston Villa on Wednesday. Juan Mata drops to the bench, while Demba Ba has not travelled north.
So one change for United after the 4-1 win at Swansea on the opening day - Wayne Rooney comes in for Ryan Giggs, who drops to the bench. Ashley Young is on the bench too after injury, involved for the first time since April.
Gary Cahill's been speaking to Sky Sports' Geoff Shreeves ahead of kick-off. The Chelsea defender admits that it's 'a cracking game for the neutral' and when asked if he can provide any clues to the Blues' initial approach tonight, he added: 'Play your way into the game. The first 10 to 15 minutes will be very lively, what with the two managers and the fans.'
We're awaiting the team news, but one thing we do already know is who's refereeing tonight - and that's a point of slight controversy. Martin Atkinson has been selected by PGMOL chief Mike Riley to oversee this one. He was in charge when United lost 2-1 at Chelsea in March 2011 and Sir Alex Ferguson's criticism of the official resulted in a five-game touchline ban for the then Red Devils manager.
The lack of transfer activity at United has frustrated many fans so far this summer, and Moyes adds: 'There is no doubt we are in a transitional period at the club - most people recognise that when a new manager joins - but I'm hoping that it's going to go smoothly and there won't be too many bumps along the way.'
Let's kick off tonight with David Moyes' programme notes for his first home league match as United boss. Having sold a record 63,000 season tickets for the new campaign, Moyes tells the fans: 'I won't be taking that support for granted. I know I have to earn it. I know I have to go out there and show you fans, and everyone at Manchester United, that I'm the right successor.'
