Image source, APEngland captain Alastair Cook: "The lads played really well. It was tough to bat but the way Nick Compton played after being out of Test cricket for a while, he was a rock int he first innings to give us a platform, and then we bowled well in both innings.
"The bowlers mixed their pace and were relentless. It's pretty easy to captain because you know they will deliver. We didn't quite get the results in Abu Dhabi so it's good to get this result."
How bizarre. As Hashim Amla was speaking, South Africa tweeted that they have added two players to their squad for the second Test. Chris Morris covers Dale Steyn, while keeper Quinton de Kock's call-up suggests a reshuffle.

"I think Amla will captain the side at Newlands but I wouldn't be surprised if it's someone else for the third and fourth Tests."
More from Hashim Amla: "It's more about confidence. Once you get runs, you play differently. The only way you can do that is get the runs. We have to patient with the younger guys.
"Dale Steyn is injured, so I think there will be a replacement. I'll leave the rest to the selectors.
"England are a good team. The series will be a contest and hopefully we can make it tougher for them."
South Africa captain Hashim Amla: "Dean Elgar played superbly. It was great to see him at his best. I'm really happy for him.
"I can't fault the bowlers. They were exceptional in India and here. They have kept the team in a good space in that regard. We just need to get the runs on the board.
"The wicket played better than we thought it would, but we would have taken them to be 40-3. Our first innings batting let us down. We couldn't put the pressure on them."

"Jimmy Anderson will be desperate to get back in, so he's not forgotten, so people don't start saying Stuart Broad's better when he leads the attack."

Charles Coldman: Clinical. Ruthless. Not words you often associate with an England Test performance overseas. SA were woeful mind.
Caroline: Well done England! A wonderful win!
Neil Gupta: Stupendously good result for England in the cricket
Moeen Ali has emerged from the dressing room, so it looks like he will be named man of the match.

"South Africa could improve their team immensely in one swift stroke by stopping Amla having to have the captaincy and AB de Villiers keeping wicket. They're roughening up two of their diamonds."

VillanUK: They think its all over, it is now. Well done Eng, fantastic performance.
THE MIGHTY ARSENAL: And done!! Broad tidies up Morkel. England win by 241. Fantastic performance by the boys. On to Cape Town 1 nil up.
Vlad Родился царь: As a South African, losing so convincingly to a fairly average England team is very disturbing...

"That wicket in the first over just killed South Africa off. I can't believe it's actually got this close to lunch after that. They just fell like dominoes afterwards."
South Africa's last seven wickets fell for 38 runs - in the middle of that they lost 5-7. Without question the biggest one of the lot was AB de Villiers, lbw to Moeen Ali in the first over of the day. After that, it was a matter of time.

Remember, England had won only one of their previous 15 overseas Tests. The tourists have James Anderson waiting in the wings, while South Africa have a host of problems.
