Shaun Edwards has urged Wales to tighten up their defence from turnover ball as they prepare for the threat of England's strike-runners.
Friday night's Six Nations opener at the Millennium Stadium will see Wales aiming to halt a run of seven Tests without a win. England, meanwhile, have not triumphed in Cardiff since 2003, the year they were crowned world champions under current manager Martin Johnson's captaincy.
But if Johnson's men are to end that barren run in the Welsh capital, England's dangerous back three of Ben Foden, Chris Ashton and Mark Cueto could play significant roles. And the warning signals have not bypassed Wales defence coach Shaun Edwards as he prepares a squad bolstered by the return of fit-again Lions Jamie Roberts, Leigh Halfpenny and Shane Williams.
"England's back three can be lethal from turnover ball, and it is something we need to improve our defence on," Edwards said. "It was definitely our Achilles heel in the autumn. When we turned the ball over, we were punished. We have to react more quickly."
Wales coach Warren Gatland is due to announce his starting line-up tomorrow.
