It's big from De Kock. This time Willey is punished, belted down the ground for a straight maximum. England really on the back foot here.

"Reece Topley had a tricky time against Chris Gayle... and now's he's got Quinton de Kock launching at him."

Reece Topley will take the new ball from the other and his first ball is short, wide and right in Quinton de Kock's hitting zone. At least it is for a brief moment, before it's sent sailing into the night sky and over the midwicket fence. Welcome Reece. Two balls later De Kock shimmies down the pitch, opens the face and lofts the ball into the same area - four this time. Topley's melting here. Wide again, this time crunched through the covers for four.

The final ball sneaks through De Kock's defences and hits him on the pad, and Topley - eyes bulging, arms aloft - pleads with the umpire to give it out. No dice. Pitched outside leg.

"A good start by Willey, just two runs. He was looking for swing, but by the naked eye there's not much, if any. He was on target though. Let's see if Topley can get it to move."

Tim Wiliams: Seriously, what does James Vince need to do to get a go in this team?

Benjamin Copp: Whilst I don't endorse panic changes, England never seem to change their team at tournaments, they're very predictable.

Willey is looking for swing into the right-handed Amla, away from left-hander De Kock. When he gets too straight to Amla, the impressive beard gets the Proteas under way with a single. De Kock can’t get it through the in-field, only taking one of his own off an edge to third man.

We've had the anthems and the players have made their way to the middle. Quinton de Kock and Hashim Amla and are a familiar pair of South African openers. David Willey has the ball.

"England failed to get significant early wickets against West Indies. They have to get them here tonight."

The players are out for the anthems. With England in pink and blue and South Africa in yellow and green, we're very colourful. There looks to be a few English fans in Mumbai, plenty of flags are being waved.

I know you must get this all the time, Gilad, but wasn't Lipschitz the name of the doctor in Rugrats? What an outstanding kids TV show that was. (Or still is. Is it still going?)

Gilad Lipschitz: What's the point of taking Dawson, Plunkett & Vince if they don't get selected to play?

"England were intimidated by Chris Gayle and greatly inconvenienced by a wet ball. I did ask Jos Buttler if they ever practise with a wet ball. He said that they do."

Taking a look at the South Africa line-up, you can't exactly accuse the Proteas of subtlety, can you? Morris, Abbott, Steyn and Rabada - four-pronged pace. They've parked the tanks on the lawn.

England: Roy, Hales, Root, Buttler (wk), Morgan (capt), Stokes, Moeen, Jordan, Rashid, Willey, Topley

South Africa: De Kock (wk), Amla, Du Plessis (capt), De Villiers, Duminy, Miller, Morris, Abbott, Steyn, Rabada, Tahir

Dan Armstrong: Massive fixture this one, every match a knock out game now for England

Also, the other day I saw that one of my friends has changed an old cricket bat into a coat hook. Do let me know of other uses for cricket equipment. A box would make a good ashtray, right?

Good news for England, but it does mean that pressure will be on a bowling attack that was below its best against West Indies the other night. South Africa, remember, beat England twice in this format earlier this year.

South Africa captain Faf du Plessis: "To be honest I wasn't sure [what to do at the toss]. There are benefits to both - the ball swings a little bit later at night but there's dew as well. The IPL experience helps a lot - Indian conditions aren't foreign to us any more. It's a nice-paced wicket so we're playing the extra pace bowler."
