Andrew McGlashan: David, South Africa batted on today, built up a huge lead and were led by AB de Villiers with 174. He played a superb innings, continuing from where he left off yesterday.

David Lloyd: Yes, all the plans were perfect for South Africa - just to grind England down. It was quite clinical batting. AB de Villiers probably played out of character, he has a reputation as a dasher, as a hitter, but he knew what his team required and that was to grind England into the ground and extend this lead into one that would make sure that England cannot win this game and leave South Africa with plenty of time to finish off the job. He played superbly well, he really did. And I should think that Graeme Smith must be absolutely thrilled - win the toss, let's have a bowl, England 203 all out, pile on the runs and get a massive lead.

AM: de Villiers has settled in at No. 6, but when he made his debut against England a few years ago - he was an opener, he was in the middle and he was stunted around. [Now] he seems to have found a good home in the middle order there.

DL: Yes, and it's not a bad thing, is it? Especially when you have two settled openers, as South Africa have with Neil McKenzie coming back into the team. They obviously want de Villiers in the team so where do they slot him in? At No. 6. In theory, he could be in there when the new ball is taken and you think, well, we've got an opening batsman in that slot. What pleased me about his innings is that he played [according to] the situation for his country; put that massive stand on with Ashwell Prince and England were completely demoralised. I should think that England would have said that de Villiers can't keep on playing like this, he will give it away, but he didn't. He batted on and on and they were absolutely ground into the ground.

AM: Michael Vaughan went through all his bowling options; there was a little bit more movement I thought today than yesterday. But it still looked a pretty short, from the England attack as a unit?

DL: Again, it was a complete mystery that there was movement there. Just a theory - the pitch has dried out and the cracks have just started to open a touch and it's Headingley, so maybe that the movement that we saw, the little movement, was off the cracks and not off the damp surface.

I thought the new guy, [Darren] Pattinson, perhaps put the best spell in. He put a seven-over spell in and took a wicket, but there will still be debate about his selection. I have talked about being ground in to the turf, and [Andrew] Flintoff with all those overs was his [Vaughan's] go-to man again and you would think that Flintoff is in this team as a shock bowler, four, five overs and off. But he kept increasing the over count, and Jimmy Anderson, I should think that he needs to be wheeled onto the next cricket ground. Anderson bowled okay. Stuart Broad, I would say, was exposed in this game, and maybe that England think again [about him]. The young chap's doing really well, but let's not get clouded on the issue that he bats a bit at No. 8. He is in there to take wickets and he is taking them at fifties.

AM: Do you think England have got themselves in a bit of a muddle with selection, having been consistent for six matches they now have the issues? Do they pick Broad for his batting or for his bowling? Then you've got Flintoff at No. 7 and [Tim] Ambrose at No. 6. Suddenly there seem to be a lot more questions than two weeks ago.

DL: I think the back-to-back Test matches, with England having to bowl twice quite quickly against South Africa, who followed on at Lord's, has made that more of a problem for the selectors. There were just three days in between the Test matches and so many of them coming in with a little niggle here and there. The youth of Broad, and we believe that he was carrying a slight injury.

I go back to what I said a couple of days ago - is there need now to go football style and for a manager to say, 'Look, I am going to get fresh legs in, two seasoned bowlers.' It could have been Simon Jones to come into this attack. Ryan Sidebottom was unfit for this game. so he could be ready for the next one. So, many headaches for England, especially with regard to their selection. Tim Ambrose is not a No. 6. They've got to decide Flintoff's role, if he is the allrounder then he has to bat at No.6. They wanted him bowling, they really wanted him back, and any runs that he gets at this stage is a bonus. He scored 17 runs in the first innings. But, it will be an interesting selection for the next Test match.

AM: I just want to mention something that is a bug bear of your fellow commentator, Michael Holding - England's use of subs. They were going on and off, I mean the twelfth man seemed today seemed to be the busiest guy today, on and off every over. What is your stance on that? I know that ICC is about to tighten the laws

DL: That's in October, I think and that comes to an end and quite right. The twelfth man, Gary Park, I assume, he will be having a rub down by the physiotherapist because he is the one we've seen all the time. It's a practice that is totally wrong. The laws of the game cover it, quite clearly that you can only leave the field if you are injured. Need to find out what the injury is, and I don't think that it is good enough just to say to the umpire that 'I have got a sore toe,' or 'I have got a strain on my thigh,' because they are clearly just going off for a rest. All teams do it. Holding, I am not sure he is till on that ICC committee, but he has been recently, and he was part of the decision making that it will be zero tolerance for that. Yes, you can go off the field, no problem at all but you can't have a sub.

AM: England are a long way behind and they are pretty much in a very similar position South Africa found themselves in on the end of the third day of the last Test. They came out and batted, and there was immediately seemed to be more movement for [Dale] Steyn than it has been for England bowlers and they lost early wickets. It's an uphill struggle now, isn't it?

DL: Very much so, and the time is on South Africa's side. They will have six sessions on the last two days with the weather, unbelievably, set fair. We are told that we are going to have some decent weather. So South Africa would say that we would close this game. England, let's see some real rear guard action, just as South Africa did at Lord's. Can England batsmen bat for six sessions? It will be unbelievably tough, and I am not sure that we've got the best line-up to do that. What you do need is a couple of batsmen scoring massive hundreds. You need a big partnership and [they need] to wear these bowlers down. South Africa will come really hard at England on day four and day five.

AM: Well, it's a huge task for England to save this game. South Africa did it last week, can England replicate it? This is Cricinfo Talk
