England flanker James Haskell insists his side is better equipped than 2011 and will thus avoid a repeat of their painful Dublin defeat on Saturday.
Under former coach Martin Johnson, England were one game away from a Grand Slam four years ago but crashed at the final hurdle against Ireland.
But back-row Haskell believes that Lancaster has now instilled the necessary tools to make it three wins from three in this year's Six Nations Championship.
"It was a very different place in terms of the structure with England and the coaches and where we were," the Wasps forward told Sky Sports.
"I don't think you will ever see an occasion where something like that [Grand Slam collapse in Dublin] happens because boys are too experienced.
"The squad has moved on now.
"Everyone back then still wanted to play for England and play well, so I think they get a harsh rap.
"But with Stuart [Lancaster] coming in, we have a game plan that is very clear and concise and it suits the players that are playing it. That is the difference."
