England head coach Stuart Lancaster is still scratching his head as to how his side lost at Twickenham, but said his side's indiscipline cost them. 

Dan Biggar was faultless with the boot as he kicked 23 points, and the head coach admitted feeling devastated by the loss.

He said: "We're absolutely devastated losing the game from being in a position where we were playing well and had dominance on the scoreboard.

"Unfortunately we gave away penalties and Dan Biggar - world class goal-kicker he is - kept them in the game."

The biggest talking point after the game was Chris Robshaw's decision to go for the corner with two minutes to go, turning down a shot at three points and a draw.

The skipper said: " That all comes down to myself.

"I spoke to the kickers and we decided we wanted to go for the win.

"It was a tough kick, we weighed up the options, but we wanted to go for that win.

"The two line-outs before I thought we had good ascendancy in the drives, but unfortunately it didn't come off.

"It hurts like hell at the moment for myself and the other guys.

"We feel like we've let a lot of people down who had come to support us."

His coach was hardly sympathetic, and said of his captain's decision: "It's a big call and if you go there, you have to nail it. We didn't.

"The boys are gutted, but it's more frustration about the penalties to let them stay in the game. That was the difference, really."

It's a result that had shunted the chariot, but Lancaster was keen to stress it was far from all over.

He said: "There's absolutely no doubt it's knockout rugby.

"Our game against Australia now becomes a knockout.

"Teams in the past have lost a pool game and got to the final.

"Everything has to go now into beating Australia."

Much of the pre-match hype evolved around Sam Burgess, and Lancaster said the centre played well.

He added: "I thought the team played well - especially in the first half - and Sam was a part of that.

"Overall, it's not about one player, it's about all 23 and the result.

"It sometimes happens when you don't pull away enough to force the opposition to play in a particular way.

"We didn't get enough distance from them and as they grew in confidence they expanded their game and started causing us problems.

"When we're 19-9 ahead - we need to be able to pull away from that."

England lost Youngs brothers Tom and Ben, Billy Vunipola and Courtney Lawes to injury in the brutal encounter.

Skipper Robshaw, when asked whether his team had lost it or if Wales had won it, said credit had to go to Gatland's men.

He said:  "They put us under pressure and made us make silly choices.

"I don't think you make those silly choices for the sake of it, it's pressure or fatigue.

"We're extremely annoyed we gave away so many penalties."
