Fly-half Stephen Jones says they cannot afford a repeat of their error-strewn performance against England when they take on Scotland in Saturday's RBS 6 Nations clash.
Wales were uncharacteristically sloppy in possession and it was Jones’ loose pass that led to allowed Delon Armitage to intercept to set up England’s decisive third try in the 30-17 defeat.
Warren Gatland though issued a vote of confidence in that team by only making two changes with Luke Charteris and Tom James dropping out of the starting XV.
But Jones knows New Zealander Gatland will not be afraid to ring further changes unless he sees a big improvement in the match against Scotland.
He said: “There are only a couple of changes for this game against Scotland, so the coach has shown a lot of faith in the boys.
“It's up to us we repay that faith and perform this week, because last week we weren't as sharp as we should have been. There are no excuses anymore.
“It's going to be a tough challenge - we respect Scotland. We know how well their teams are doing in the Magners League.
“We have got to cut the errors in our game, because we know when we are accurate we are a very good side.
“We were particularly disappointed with the way we performed against England.
“Yes, we have to give England credit because they played well, but the problem from our perspective was that we took so much away from our own game just from our own inaccuracies.”
