Wales caretaker coach Rob Howley admitted that the Six Nations champions could only blame themselves after Friday's 26-19 loss to Samoa in Cardiff.
Wales were outplayed in most facets and showed no improvement after last weekend's defeat to Argentina.
"I have spoken to the players and we are obviously disappointed as a coaching team and group of players," said Howley
"International rugby is about discipline and when we created opportunities in the game, although we did not have many, we were disappointed in terms of our top-three inches at times.
"We were outperformed by a Samoa side whose ability to keep the ball better than us was the most disappointing aspect of the performance.
"We did not have control of possession or in terms of the contact area and that is obviously not international standard."
There were more injury woes for the Dragons with hooker Richard Hibbard, fly-half Dan Biggar (both shoulder) and lock Ian Evans (knee) all doubtful for next weekend's clash against New Zealand in Cardiff.
Meanwhile, Wales blindside flanker Ryan Jones, who captained his country for a record 29th time, said the defeat was difficult to accept.
"What could have been the greatest day of my career has turned into one of the worst," he remarked.
"We came second best in quite a few facets of that game. It was a game that slowly slipped away from us and we didn't have enough in the end.
"But that's not taking anything away from Samoa, who turned up with a physical edge and a game-plan that stopped us playing again."
