After impressive victories over Ireland and Scotland in the opening two weeks of the RBS 6 Nations, Wales will look to put themselves in pole position to claim the title with victory in England's back yard.
History is against Warren Gatland's side as Wales have never won a Triple Crown at Twickenham and it would require a rare victory on English soil to do so.
But Roberts, who has carried on his superb form from the World Cup in this year's RBS 6 Nations, insists Wales' only aim is victory.
"If we take our 'A' game down to Twickenham then I certainly think we can turn them over. It is all about producing the goods on the day," he said.
"If we do that, we win a Triple Crown, which is a pretty special feeling. The boys do not need any motivation.
"From players, to fans, to family, Wales v England is always the big one. All fans across England and Wales will be watching the game with huge anticipation.
"To play in it is such a special feeling, be that at the Millennium Stadium or Twickenham.
"To beat England away from home is one of those feelings in rugby that a lot of us players aim for, not just for bragging rights.
"It is a place where we haven't won many times over the past couple of decades and it is a very tough place to go and win.
"2008 is obviously one that sticks in the memory so we just need to repeat that. It would be massively special."
