Lawrence Dallaglio heads into Wasps' Powergen Cup semi-final with Leicester determined to win his "one-on-one battle" with England captain Martin Corry.

Should Dallaglio succeed at the Millennium Stadium, the repercussions could be far reaching as England head into their RBS Six Nations Championship clash with France in Paris.

In what has been billed as something akin to an audition not only for the No 8 England jersey but also the captaincy, the outcome of tomorrow's Wasps versus Leicester contest takes on extra significance.

Dallaglio, who returned to the England squad this season after 18 months in international retirement, has replaced Corry in two of England's three championship games.

And he is determined to keep the pressure on this weekend by turning in his best performance of the season to help Wasps reach the inaugural Anglo-Welsh Powergen Cup final at Twickenham.

"If either side is to prevail then there are some key oneon-one battles you have to win," said Dallaglio.

"I view every game as a chance to press my England claims. Hopefully that will be a consequence of the result and what happens in Cardiff.

"What we all want is to see England be as successful as possible. Martin and I are no different.

"For that to happen we need everyone playing as well as they can and causing selection problems. That is the challenge we all face.

"I am there in the England squad to compete and hopefully that might turn into 80 minutes. Until then I must work as hard as I can to force myself in.

"I'll have to play well this weekend because you can't be anything other than that to beat Leicester. It will take our very best performance to win."

Dallaglio has been accused of "talking his way" into the England team and the issue over his role alongside that of captain Corry has dominated this year's Six Nations.

It is a position Dallaglio insists he feels uncomfortable with, but he believes it to be vital for England's chances of success over the next 18 months heading into their World Cup defence.

"A lot of attention seems to be focused on myself and Martin and that mustn't detract from the team. That has not been my ambition," he said. "I want England to be successful. Obviously I want to be in the team, but you have to earn your place in the team."

Dallaglio confirmed his commitment to the England cause for the long haul and vowed he will not be bowing out of the international scene just because he is being limited to a replacement role.

"I am very, very committed to the England cause. I was as disappointed as anyone that we lost against Scotland at the weekend," he said.

Nevertheless, Dallaglio believes he plays his best rugby as a member of the starting XV, so warming the bench for England and Wasps over the last few weeks has been frustrating as he looks to rediscover the form that earned him British & Irish Lions selection last season.

Dallaglio returned from England duty against both Italy and Scotland to turn out for Wasps in the Guinness Premiership just 24 hours later. But he is looking forward to getting stuck into tomorrow's game right from the opening whistle.

"The role off the bench is a different one and one I have to get used to," he said.

"When you are on the bench you are given limited opportunities so you have to be patient and try and take that opportunity when it comes.

"There is still a long way to go to reach the form levels I believe I can reach. This weekend we all want to play as well as we can and hopefully I am timing my run of form to peak in the last few weeks of the season."
