Ex-England batsman on BBC Test Match Special"England are sitting so pretty there's no chance that South Africa will get any target England set and there's only a slim chance of South Africa saving the Test.
"England can be sensible this morning and by lunchtime without doing anything silly they should be able to get to a 350-lead and then that should enable them to have a dart after lunch and decide when to declare."

07:47So, what to make of all that? Are England on top in this match because of their superiority, or are they being aided by South African disarray? A bit of both?
And are you back to work today? How will you be remaining in the cricketing Christmas spirit?

South Africa team manager Mohammed Moosaji: "Steyn has developed a stiffness in his shoulder, partly because he has just come back from a groin injury. The scans have all come back as inconclusive.
"He's still in pain. It's unlikely that he will bowl today and we will monitor him to assess to see if he can play in Cape Town.
"If he wakes up tomorrow and the pain subsides, then he will be considered, but at the moment it's too early to tell."

07:44Wilting not only in this match, but creaking in the bones as well.
South Africa pacer Dale Steyn left the pitch not once, but twice yesterday with a shoulder problem.
We were told last night that his would be assessed before play today.
Well...

07:42Oh ye of little faith. Allow us to extend the festive cheer and ease you back to reality with a cracking Test match - one that England are well placed to win.
The tourists resume on 172-3, a huge lead of 261 over South Africa - the world number ones, no less.
Alastair Cook's men have two further days to pick the petals off the wilting Proteas.

07:41Although we're very much still in the spirit of Christmas, it's undeniable that the season is passing us by.
Drinks on Christmas Eve. Presents on Christmas Day. Leftover turkey every day since.
Now, the alarm clock and the rush to get back to work (complete with turkey sandwich in your bag).
How depressing.
