Proteas choked, says Kirsten

"We need to be honest with ourselves.

"I think we did choke again today," Kirsten said after the disappointing one-sided game at the Oval that lifted England into their second Champions Trophy final.

"It's a horrible word but we have to front up.

"We let ourselves down today."

It was the first time a South African coach had publicly accepted what was widely believed in the rest of the cricket world -- that the Proteas faltered in crunch games.

South Africa, the top-ranked Test team and a formidable opponent in world cricket, have struggled to get past the semi-final stage in major one-day tournaments since winning the inaugural version of the Champions Trophy in Bangladesh in 1998.

Alastair's Cook men outplayed the Proteas after electing to bowl on an overcast day at the Oval where England had lost to the West Indies in the final of the same event in 2004.

South Africa were reduced to 80-8 by the 23rd over before a record ninth-wicket partnership of 95 between David Miller and Rory Kleinveldt gave the total some respectability.

But Jonathan Trott hit 82 not out and Joe Root made 48 during a 105-run stand to help England surpass the modest target in the 38th over of a disappointing semi-final.

Kirsten, the former South African opener who ends his two-year term as coach with Wednesday's match, said he had expected his team to perform better in the semi-final.

"I think we had better expectations of our performances," he said.

"To be blown away with the ball with the quality of batsmen we have got in our batting line-up is very disappointing."

"There has definitely been an inconsistency to our cricket.

"When we play in big tournaments like this, we do get exposed."

Kirsten, who coached India to victory in the 2011 World Cup before moving back to South Africa, said he shared the blame for the team's debacle.

"Do I leave the team in a better state? I don't know," he said.

"We certainly have not improved, and that is where a question mark needs to come over me.

"So maybe it's a good decision that I'm leaving."

England captain Alastair Cook disagreed with Kirsten and thought his side had won the right to meet India or Sri Lanka in Sunday's final rather than South Africa throwing it away.

"I don't think they choked, I think we played really well," he said.

"You are always trying to keep your foot on the throat."

Steven Finn impressed after coming in for Tim Bresnan, whose partner gave birth to a boy, and James Tredwell again stood in for injured spinner Graeme Swann and took three for 19.

"It's going to be a very tough selection call if Swanny is fit.

"It's a good headache to have," Cook added about both bowling spots as 2010 World Twenty20 champions England face their first 50-over tournament final since 2004.

"As kids you always grow up wanting to play finals. Finals can bring out the best in people."

Cook was confident his team can win Sunday's final at Edgbaston, Birmingham, against the winners of Thursday's all-Asian semi-final between India and Sri Lanka in Cardiff.

"We can win it, without a doubt," the England captain said.

"You need people to stand up and deliver to win one-day internationals and it has happened for us in the last two games we have played.

"This England side in particular has delivered when the chips have been down and the pressure has been at its highest. So I have no doubt that our guys will turn up on Sunday and do it.

"Hopefully it's now our turn."

Cook, whose team begins the highly-anticipated Ashes series against Australia next month, said it would be a "great achievement" to win the Champions Trophy.

"It's hard to compare it with the Ashes, but at the start of the summer we set out some clear goals and one of them was to win the Champions Trophy," he said.

"We got to the final in 2004 and we could not quite get over the line. Hopefully this time we can go one better."
