There is applause for no particular reason. It's that sort of morning!

There's something about a Sunday crowd which is just a bit different.

James Pattinson to Joe Root first up.

A very full ball that Root jams his bat down on and pushes into the off side.

He starts off for a run, sees it's not on and turns back.

The crowd applaud. I think they will cheer everything England do that isn't a wicket today.

I can see tears in the eyes of one lady in the stands. We haven’t even started yet.

A huge cheer as Joe Root and Ben Stokes make their way out to the middle.

Australia are taking up their fielding positions.

Inhale.

Exhale.

Here we go.

England have never chased as many as 359 in the fourth innings to win a Test. Could this be the day they go top of this pile...

• 322-7 v Australia, Melbourne, 1928
• 315-4 v Australia, Headingley, 2001
• 307-6 v New Zealand, Christchurch, 1997
• 298-4 v Australia, Melbourne, 1895
• 294-4 v New Zealand, Old Trafford, 2008

There was a big group of people already with pint in hand outside my local Spoons on my way into work this morning at about 9.30am.

I trust they are all nervous England cricket fans.

Is any time too early on a day like this?

Ah yes, so confident was Shane Warne that Australia would wrap up victory yesterday, he checked out of his hotel room.

Did the Western Terrace manage to book up every room in Leeds after finding out?

If you think it's gone, the game is already over. There's still hope. For England to win the game, it will take a long time. For Australia to win the game, it could happen very quickly. I'd rather be Australia.

Australia batsman Steve Smith batted against bowlers in the nets today for the first time since being pulling out of the Lord's Test with a delayed concussion.

The session lasted 25 minutes and he also did some high intensity running.

He's due to play in the tour match against Derbyshire, starting on Thursday, as preparation for the fourth Test at Old Trafford, which begins on 4 September.

BBC Weather's Philip Avery: "The weather is not going to get in the way of play today. The temperatures are pushing 27 and 28C. What cloud there is thin and clear. The new ball will be the biggest problem for England; I don't think it will be be swinging."

Right, for our younger readers who may not know why there has been (and perhaps will be) some many references to 1981 so far...

In the third Test of the 1981 Ashes, Australia - who were leading the series 1-0 - posted 401-9 and bowled out England for 174, enforcing the follow on.

Ian Botham smashed 149 not out to lead England to 356 in their second innings and set Australia 130 to win.

Bob Willis then took 8-43 to skittle the Aussies for 111 and England went on to win the series 3-1.

Jack Leach was the last England batsman to leave the nets this morning. England will certainly hope their number 11 is not needed. Then again, there are worse number 11s.

TheOldBakery: It's going to be tough. these 2 need to get hundreds to have any chance. 1 early wicket and it could be over before lunch.

England batsman Joe Denly, who fought to 50 before gloving Josh Hazlewood behind, firmly believes his side can pull this off...

"I rate our chances very highly," said Denly.

"There are not too many demons in the pitch - we are in a very good position.

"There is a lot of belief and excitement in that changing room."

A reminder that if England pull this off, it would be the second highest successful fourth-innings chase in Tests at Headingley.

• 404-3: Australia v England, 1948
• 322-5: West Indies v England, 2017
• 315-4: England v Australia, 2001
• 219-7: England v Pakistan, 1982
• 186-5: England v South Africa, 1929

Ah. Yeah. Australia get a new ball in eight overs to throw to Josh Hazlewood, Pat Cummins and James Pattinson.

That pace trio have been tremendous in this Test and throughout the series.

Together with Steve Smith, one excellent day from Nathan Lyon and Marnus Labuschagne's late influence, they are a big reason why Australia look set to retain the Ashes here.

Can England repel them or at least limit the damage they do with that new ball in the first session?

For England to have a chance, Root and Stokes have to get through the new ball. England have to make Australia work hard. If there is a partnership early, there could be ebbs and flows today...
