Wales captain Sam Warburton has admitted that Saturday's World Cup group match against England is one of the biggest clashes in the history of the fixture.
Both nations won their first matches in Pool A, the Red Dragons cruising past Uruguay 54-9 at the Millennium Stadium and England beating Fiji 35-11 at Twickenham.
With both teams still to face Australia in their quest to progress to the knockout stage of the competition, Warburton admits that the showdown at Twickenham this weekend is one of the most important games ever between the two countries.
"You know that it is coming, and it is a huge game," he told reporters. "It is one of the biggest Wales versus England games in history.
"It will probably be the most-watched game, including a Lions Test series. This is probably the highest-profile game of my career, I think.
"I read that there has been more demand for these tickets than for World Cup final tickets. That hits home how big it is. Unless we meet again in the final, you never know, this will be the biggest game that I have played in."
Going into the match, Wales are edging England on points difference in Pool A after their respective openers, with both sides a single point ahead of Australia after the Wallabies missed out on a bonus point in their victory over Fiji on Wednesday.
