The main issue England need to address before taking on Wales is how to fire up their spluttering attack in the face of a defence that conceded only two tries in the whole of last year's RBS 6 Nations.
Joe Worsley has been brought in to try and counter Martyn Williams at the breakdown in the hope of securing quick ball.
But even if they get it, there is little evidence that England have the panache required to break down the mercurial Shaun Edwards' defence.
Haskell, Worsley, Phil Vickery, Riki Flutey and Paul Sackey all know Edwards inside out from club duty with Wasps.
But Sackey warned England not to get too complacent just because Edwards is so familiar - because he is likely to sell them a massive dummy.
“Shaun and Warren Gatland know there are a lot of Wasps guys here and we have a little bit of an insight into how they defend,” said the wing.
“They know that we know what they do and because of that I think they will change things and do things differently.”
Sackey believes the criticism England received for their unimaginative performance against Italy was unfair.
“It was our first game after such a disappointing autumn series. It was important just to get a win under our belts,” he explained.
“We may have tightened it up and been a bit cautious but we got a win under our belts. Five tries in an international game is quite convincing.
“It is quite harsh for people to be saying what they are saying. We know we didn’t play to the best of our ability and at the moment and we still have a lot to work on.
“But we want to play with a bit of expansion, to get the wingers into the game and we know we have the players to cause problems against the Welsh.”
