Valencia and Lingard give United two-goal lead
Lacazette pulls goal back before Lingard strikes again
Pogba sent off for late foot on Bellerin - he misses Manchester derby
Arsenal 0-2 Man Utd
Mesut Ozil - will we see 'good Ozil' or 'bad Ozil' today?
Anyway, the German's low snapshot from eight yards flies straight into the hands of David de Gea, as Arsenal keep pressing.
Either side etc etc

Dennis Ethan: How on earth didn't that go in? A big let off for Man United
Peter Collins: How on earth have Arsenal not scored? Or even had a shot on target I'm there?!

It. Is. All. Happening.

Ozil floats the free-kick towards David de Gea's near post, but it sails so slowly over the wall Ashley Young has time to get back and head clear from the goalline.
De Gea probably would have saved it.
Accurate free-kick, but weak.

Ozil to take it?

Hannah Wood: Worth getting up at 4am with the kookaburras in Australia to watch United get off to a great start! Let’s keep this high pressure up lads
robby S: Arsenal fans, WINTER IS HERE!!! Very cheap goals to concede....
Arsenal 0-2 Man Utd
Alexis Sanchez loses the ball near the edge of the United area, allowing Paul Pogba to break.
United's French midfielder surges forward and produces a lovely backheel flick to keep the move flowing.
However, the attack breaks down 20 yards from goal.
The visitors definitely fancy it today.
0-5? Or....
It's an Arsenal free-kick at the other end.

Breather.
Jesse Lingard receives treatment on the deck.
The goalscorer is OK though.
It gives United boss Jose Mourinho time to dish out some instructions.
While we wait for the next bit of action, here's a stat:
United (2) scored more goals inside the first 11 minutes versus Arsenal than they managed in their previous eight away Premier League games vs the big six (one goal) .

All the good work of the last few games undone by atrocious defending
Ross, Hampton
Arsenal 0-2 Man Utd
Will it be one of those Arsenal days?
Manchester United attack down the right again. It ends with Nemanja Matic's shot blocked.
Straight at the other end, Arsenal try to score through Mesut Ozil, although it looked more like a pack trying to get over the tryline.
Seconds later, Alexandre "The Miracle" Lacazette almost pokes in from close range.
He doesn't and it's still 0-2. Exciting though folks.

Richard: What a touch from Martial. That's ridiculous
Dharma Djojonegoro: “Lionel” Lingard strikes again
Mickey Wallis: I did not get up at 4am in Australia to watch Koscielny and Mustafi gift Man U a 2-0 lead inside 10 minutes. Going back to bed
Arsenal 0-2 Man Utd
Now then.
Shkodran Mustafi - if you remember he's the player who made the mistake that led to the second goal - hobbles off and is replaced by Alex Iwobi.
Not a day to remember for the German.

Jesse Lingard
More great Arsenal defending.
Shkodran Mustafi dallies on the ball and loses possession about 25 yards from goals.
Jesse Lingard nicks the ball, finds Romelu Lukaku who feeds Anthony Martial who in turn delivers the ball back to Lingard who pokes past Petr Cech.
That's 2-0 folks - inside 11 minutes.
Image source, ReutersArsenal mount another attack though.
Mesut Ozil motors down the left and pulls the ball back for Sead Kolasinac to cross.
United, however, clear.
Wait...

Ash Williams: Arsenal not got going, not pressing. United ghosting past Arsenal defenders. Players look like they expect to lose to a rival.
Neil Moriarty: You gotta look at Cech for that goal.
RegularJon: well well well, the bus knows how to pull off in 6th gear! mufc great start
Arsenal 0-1 Man Utd
It cannons off the wall.

Can Arsenal bite back?
Chris Smalling catches Alexis Sanchez about 20 yards from goal.
Free-kick to the Gunners.
Sanchez steps up.
Antonio Valencia
Yup.
What a superb start for the visitors.
Laurent Koscielny's pass to Sead Kolasinac is cut out by Antonio Valencia.
The Ecuadorian plays a one-two with Paul Pogba and fires low under Petr Cech.
In four words: Sets it up nicely.

Corner to Manchester United.
Romelu Lukaku, jumping about as if he's got ants in his pants, desperately calls for Anthony Martial to deliver a good ball into the area after starting the attack.
It doesn't arrive, but United win a corner.
The corner comes to nothing.
Lukaku stops jumping.
Arsenal 0-0 Man Utd
The Gunners get us under way.
After a false start.
