Gethin Jenkins has admitted that Wales have no one to blame but themselves after the reigning RBS 6 Nations champions' shambolic performance against Argentina.
Wales' 26-12 defeat was their heaviest home loss for three years and biggest reversal anywhere since subsiding to France in Paris 22 Test matches ago.
"We just didn't play in the right areas," said 91 times-capped prop Jenkins, after tries during six second half minutes by Argentina wings Juan Imhoff and Gonzalo Camacho stunned Wales. "We didn't really look like scoring at some points of the game. It's back to the drawing board."
He went on: "Argentina came with a game-plan to kick a lot and be very physical, but we played into their hands, really. We tried to play too much rugby inside our own territory, and I don't know whether it tired us out when it came to the last 25 or 30 minutes.
"They seemed to up the tempo and we couldn't live with it. We let in two soft tries and I suppose our spirit went down a little."
Argentina arrived in the Welsh capital battle-hardened from their debut Rugby Championship campaign, and they gloriously showcased the benefits of tackling southern hemisphere heavyweights New Zealand, Australia and South Africa on a regular basis.
Jenkins added: "I have played against Argentina before, but they've definitely gone up a level from where they have been.
"Playing six games against Australia, South Africa and New Zealand, they are going to be adjusted to that level of intensity. Every time you play a Tri-Nations team it is a step up.
"But we didn't perform. We made mistakes, we lost the ball quite a bit and we weren't on our game. We hate losing at home, and it was a really depressing changing room afterwards.
"We tried to play too much. I know that's a negative thing to say, but you look at the top teams and they play in the right territory and put pressure on their opponents."
