As a coach you want to be an actor. There might be times when you are angry or frustrated. But you have to portray you are calm and relaxed. The era now is different to the past.

When I'm in the dressing room as a coach I try to keep it light. Have a joke and keep a smile on my face. When I saw Brendon McCullum lying back on the sofa it puts it out there to the England players that he is relaxed. You don't want to panic them.

It’s a struggle to see some of the high rise buildings in the distance through the murk. Rain is still falling here.

Thanks, Sam.

Well, this is a bit frustrating. It is a bit of a sorry scene at Edgbaston right now but the forecast is for it to improve.

Fingers crossed the ground staff can then work their magic and we can see some play shortly after lunch.

It's 11:00 and we should be about to see the first ball of this highly-anticipated fifth day.

Sadly, the rain has done for that but all signs point to there being plenty of play possible this afternoon - more than enough to get a result.

As we continue to build-up to what we hope will be a 13:10 BST start, I'll hand you over to Tom Mallows.

It all comes down to today - it will define this Ashes series. If England get the win then Ben Stokes will continue to go ultra aggressive. If England lose they face so many questions about the declaration, their batting approach at times.

If Australia lose then Pat Cummins is under the spotlight and there's questions about spreading the field. There will be fingers pointed to whoever loses. I think whoever wins this Test will win the Ashes.

Well then. If all goes well, we're looking at two (presumably pretty lengthy) sessions to decide this enthralling Ashes opener.

A reminder that Australia are 107-3 and need another 174 runs to win. England need seven wickets.

It means there will be no play until at least 13:10 (BST) when the umpires will come out and take a look and we'll have an idea as to when we are likely to get under way. Looking out the window it's stopped raining so there are encouraging signs.

We’ve been told they have already decided lunch will be taken at 12:30 BST and there will be no play before 13:10 at the earliest.

News from Edgbaston and it essentially confirms what we probably already knew: no play this morning.

Lunch has been brought forward by 45 minutes and will now be taken at 12:30 BST.

It should mean fewer overs are lost.

We're 15 minutes away from the scheduled start time and the covers are still firmly in place.

It looks grim at Edgbaston but the ground staff are out and getting to work on the mopping up job which suggests the worst of the rain might have passed?

Stuart Broad ended the day bent double in the middle of the Edgbaston field.

The Hollies Stand, Edgbaston's 6,000-strong stag do, rose because England's 'Mr Ashes' had done it again.

England 10 Australia 0.

The Ashes was born in the aftermath of Australia winning by seven runs at the Oval in 1882, a game so tense that a spectator reportedly chewed through the wooden handle of his umbrella (an incident which reputedly led to the Gladstone government of the day legalising the hot dog for use at sporting events).

Since then, England have held the upper hand in tight Ashes finishes. Winning 15 of 20 Ashes Tests won by under 25 runs or fewer than three wickets, including all three one-wicket Ashes victories (Stokes' match at Headingley four years ago, at the MCG in 1907-08, and the 1902 Oval classic, when Gilbert Jessop set the record for fastest England Test century that the current team seem intent on breaking).

England's two-run victory in the 2005 Edgbaston Test is thus far the closest Ashes Test won by the team bowling in the fourth innings.

The most recent of Australia's five wins in these Ashes stomach-churners was an 11-run win at Adelaide in 1924-25. By way of consolation, in that time, Australia have won 24 Ashes series to England's 17, with six drawn rubbers, five of which resulted in Australia, as holders, retaining the urn.

And the answer is...

ZaltzQuiz answer time!

Here is a reminder of the question:

After a mesmerising, fluctuating fourth day, we could be set for another gripping Edgbaston finish to set alongside the 2005 nail-biter.

Since 1926, 10 men's Ashes Test matches have been won by margins of fewer than 25 runs or three wickets. How many of those 10 games has each team won?

The answer is coming up shortly!
