And an edge for four too.

Replays show Jason Roy carrying four bats back up to the dressing room. I can't decide if more bats would have helped or hindered him further.

Dawid Malan is in the sort of nick that makes you the number one in the world. He announces his arrival with a hook for four.

95mph from Nortje. Full and straight. Great bowling - great to watch.

This will be a good test for England and one they will be keen to pass. Yes, the series is won but chasing down a score like this will make a statement before next year's World Cup.

Now it's Buttler's turn!

A whallop over cow corner.

Back-to-back sixes for England.

Oh yes!

Jason Roy has his dancing shoes on, skipping and lofting for a straight maximum.

Somewhere, the analyst smiles. "I told him to do that."

Great battle between Roy and Linde, who gets a second over. Roy is looking for width that isn't there, only pouncing when Linde errs too straight.

I wonder what the analyst can signal during the runs chase? What's the code for "hit runs but don't get out"?

The captain is in charge. Sometimes a message will be brought out with some gloves or drinks. You've got to be careful about doing that because you're not really meant to. It's very clear in cricket - the captain is in charge.

It's quite difficult for the coach sat up there on the balcony. When things are going wrong, he's not able to do anything about it. He can't do a Jose Mourinho and bounce up and down. He's got to sit there quietly and not do anything about.

It will be a talking point. It's a fine line between an instruction and a suggestion which is what the ECB is saying. I will say it again - they have had it cleared by the ICC.

Straight from Nortje. Nothing for this right-handed pair to get their hands through. Jos Buttler faces five dots, then hooks his sixth for a couple. He doesn't look to be moving too freely.

Andy in Devon, I've seen your text and I can't publish something like that on the BBC.

Stuart, I've seen your text and a sure-fire way not to be published is to call me 'Stephen'.

Anrich Nortje is on to bowl his thunderbolts.

Eoin Morgan doesn't have to do anything with the information and we don't know exactly what the numbers and letters are corresponding to. They've come up with some system to give a little bit of feedback while the team are on the field of play.

I personally don't have anything against it - I think it adds another element to the game. But a lot of people may see it another way.

I like George Linde. He doesn't look threatening, just a trot up and a round-arm roll, but this is an excellent first over. Only one from it. England basically need to chase these in 19 overs now.

We're a bit intrigued here because the strategist is putting up a number and a letter - it's got people talking a bit. In cricket, all decision-making takes place on the field. It's not like a football manager situation - the captain is in charge.

There was an occasion in the 1999 World Cup where Bob Woolmer, the South Africa coach, wired up Hansie Cronje with an earpiece and was telling who/what to bowl and everything and actually the ICC got very snotty about it and banned it - quite rightly so. What's the difference? I'm not sure there is one. The ECB have said it's purely an offering, a guidance and suggestion for the captain.

I've been a bit naughty with the ECB media man and suggested that it was the seat number the ball was being smashed into next - and that hasn't gone down very well in Cape Town. People will talk about it - the captain is in charge, and of the tactics. I suspect tomorrow that many newspapers will talk about it and whether it's right or not. England have had it cleared by the ICC.

Here we go then. Jason Roy and Jos Buttler facing up to the left-arm spin of George Linde. 192 to win.

You could say that England's bowlers were lacking, or you could say that South Africa came off. It's not a big ground, Newlands, and South Africa hit 11 sixes.

I'm a massive Christmas man, so I can't ignore a request like that.

On a similar theme, is it OK for a 35-year-old man to have an advent calendar? Asking for a friend...
