Creative Mind: When we said give Emery time I didn't realise it was just gonna be for 45 minutes

Liam McColgan: Even if we lose this game, which will happen, I can only praise Emery for being dynamic, vocal , always assessing and being proactive rather than reactive. Unlike Wenger.

Kaushik Gorai: Someone explain to these Arsenal 'fans' that transition takes time. Those all who wanted Wenger to leave, this was always going to happen. What do you expect? Win the league at the very first game?

Riyad Mahrez still trying to get on the same wavelength as his team-mates.

The former Leicester man tries to pick out Sergio Aguero in the box with a cross from the right, but it is too long and away for a goal-kick.

James Greener: Arsenal fans all doom and gloom but they are playing a side that got 100 points last year, give the team a break

Wayne Ellis: First PL game under a new manager, playing against by far the best team in the country, and the Arsenal doom and gloom merchants are out in force already...

Geoff Russell: Get a grip people one game in, try supporting you team not whining and sniping.

Here comes the change at left-back - and it's not Danny Welbeck.

Ainsley Maitland-Niles slowly trudges off and is replaced by debutant Stephan Lichtsteiner.

Arsenal threaten to equalise but Henrikh Mkhitaryan cannot get a shot away, smothered by four or five Manchester City defenders inside the box.

At the back, Ainsley Maitland-Niles is struggling badly.

Ed Wilkinson: With Kompany, De Bruyne, Sane, Otamendi and Jesus on the bench, and we are still winning, it really shows how this season will go for City!

Anthony David Pletin: Wow. The silence is deafening at the Emirates. Unreal.

Dave, Bedford: Pick any Arsenal midfielder you like, one is coming off for Torreira at half time.

Ainsley Mainland-Nile does not look too good after that, but hobbles on the pitch and will try to run it off.

Arsenal might need a makeshift left-back for the makeshift left-back.

Ainsley Maitland-Niles is down on the deck and needs treatment after a foot race involving Kyle Walker.

Speedy Gonzalez v Road Runner, that.

It's actually a brilliant save from Cech here. The first save he should make but his reaction to get up and force Laporte's effort round the post is excellent.

New manager but in this first 30 minutes I have to say it has been the same old Arsenal.

The Meme Man: So first impressions are that very little has changed on planet Arsenal

Mister Dave: Can someone remind me again why Arsenal supporters were optimistic for this season?

Adebayo Bamgbose: Can we get Wenger back please? What is going on? Players seem clueless

Frenchman Aymeric Laporte then has a free header from the corner, but the Manchester City defender cannot direct his effort on target.

Should have done better.

Brilliant double-save from Petr Cech.

He gets down low to his right to push away Riyad Mahrez's free-kick, before leaping up and keeping out Aymeric Laporte's close range follow-up.

Granit Xhaka loses the ball in the middle of the park and here comes Sergio Aguero, bursting to the edge of the box before being tripped by Sokratis Papastathopoulos.

Mark Read: City are going to win the league at a canter.

Andy, Donaghadee: Emery will get to see just how "supportive" some of these Arsenal fans are now!

Neil Moriarty: I'm not gonna ask where Leno, Torreira, and Lacazette are. I only did that when Wenger was in charge...

Raheem Sterling is on top form today, he is causing Arsenal's defenders allsorts of problems.

The English international wriggles through the challenge of Shkodran Mustafi, but his cross deflects off a red-white shirt and into the hands of Petr Cech.

Absolutely extraordinary from Petr Cech. It was played back to him and in trying to pass it to Bellerin he is close to nestling it into his own net. What was he doing? You could hear the shock rippling around the Emirates.

Oh, Henrikh Mkhitaryan IS playing.

The Arsenal midfielder's attempted cross-field pass towards Pierre-Emerick Aubameyang sails out of play.

What's Petr Cech playing at??

The Arsenal goalkeeper almost puts the ball into his own net.

He will be a relieved man as the resulting corner comes to nothing.

Cech turns around and apologises to the home supporter behind his goal.

Arsenal come alive in the final third, as Hector Bellerin gets the better of Benjamin Mendy, but his shot is straight at Ederson.

At the other end, Sergio Aguero finds space down the left-edge of the box, but he shanks his shot wide.

It's been a great start from Man City. There were five Arsenal players blocking the view of Cech and you can see from how he reacts that he was unsighted. Arsenal have had a bit of respite in the last few minutes but City are cruising.
