Mitchell Starc, who had a fitness test this morning, is going to get us under way.

Jason Roy, who looked horrendously out of nick in the first game, is on strike.

The two sides are making their way out to the middle.

It is an absolutely gorgeous day at Emirates Old Trafford.

This is the sort of day where a crowd would be absolutely loving it.

Joe Root who averages 50.6 in one-day cricket and Jason Roy who has played a huge part in England's 50-over success over the last few years.

Are we talking about the same people, Dave?

Australia were pretty good on Friday, weren't they?

At times their model of playing one-day cricket looks dated with the steady scoring rate and the four main bowlers with multiple part-timers filling up the remaining 10 overs but it's working for them.

In their mind getting a score in excess of 250, rather than being bowled out for 180 trying to get 330, leaves them in the game with the excellent bowling attack they have.

Once we have 150 overs on the pitch, the second innings, with England defending, the pitch could slow up. I've felt for Sam Curran. It's good to see him play.

The good news?

England have only won more men's ODIs at The Oval (29) than they have at Emirates Old Trafford (26).

The bad news?

Their last two defeats at the venue have been against Australia in September 2015 and on Friday night.

As I mentioned in my introduction England are looking to avoid a first one-day series defeat in over three years - January 2017 to be precise, when they lost 2-1 against India.

Since then they've gone 13 series without defeat winning 11 and drawing two.

Eoin Morgan's side have also lost their last two games (the final ODI against Ireland and the Friday's first ODI) the last time they lost three straight one-day games was 2016 when they were touring South Africa.

I had visions of Steve Smith complaining that he couldn't see because of the glare off the glass of the media centre or the enormous red Point building today so I'm pretty disappointed he misses out.

Unsurprisingly it's absolutely gorgeous at Emirates Old Trafford.

In fact, it might even be the best weather we've had all summer, at the ground, for international cricket.

Strange seeming we've barely left the place throughout July and August but let's not complain too much, eh?

Word from the Australia camp is that the decision was made to rest Smith as an extra precaution after he took a knock to the head in the nets on Thursday.

England: Jason Roy, Jonny Bairstow, Joe Root, Eoin Morgan (c), Jos Buttler (wk), Sam Billings, Chris Woakes, Sam Curran, Tom Curran, Adil Rashid, Jofra Archer.

Australia: Aaron Finch (c), David Warner, Marcus Stoinis, Marnus Labuschagne, Alex Carey (wk), Glenn Maxwell, Mitchell Marsh, Pat Cummins, Mitchell Starc, Adam Zampa, Josh Hazlewood.

Umpires: Michael Gough and Martin Saggers

TV umpire: Richard Illingworth

Australia captain Aaron Finch: "We're just being cautious with Steve Smith.

"It's about playing as good a cricket as you can. England keep coming and coming and coming.

"You have to play your complete game and be at your best, otherwise they beat you.

"Our top-order missed the mark slightly in the first game, but we backed ourselves to get through that."

Before we knew the team I'd prepped a post saying the next four days felt pretty important in Moeen Ali's international career.

This summer, in the four one-day internationals he's played against Ireland and Australia on Friday, he's only scored seven runs at an average of 2.33, while he's taken 0-174 from 35 overs with the ball.

Eoin Morgan said it was tactical that Moeen misses out today but England will be hoping that Ben Stokes is available for selection the next time they play any white-ball cricket. With Stokes, Sam Billings, Dawid Malan and the Curran brothers on the edge of the squad Moeen may face an uphill battle to get back in the team.

England captain Eoin Morgan: "The wicket is the same as the other day, we didn't think there was any demons in it but it may get a tiny bit worse later on.

"It didn't spin as much as we thought it would on Friday but if you hit the right areas it had a bit to offer for all bowlers."

Despite Mitchell Starc struggling with a small injury on Friday Australia are unchanged.

Aaron Finch says "he's pulled up fine".

England have made two changes.

Tom and Sam Curran are coming in with Mark Wood - who hasn't pulled up as well as England had hoped - and Moeen Ali - who misses out for tactical reasons - drop out.

Bob Marley and Oasis soundtracking the warm-ups this morning. Give the DJ a rise.

Hello! Welcome to our coverage of the second one-day international between England and Australia.

After defeat on Friday Eoin Morgan's side must win today to keep the series alive and avoid a first series defeat in over three years.

Can they do it? We'll head out to the middle to find out if they are having a bat or a bowl first in a couple of minutes.
