Dallaglio will say an emotional goodbye to a packed Adams Park in tomorrow's Premiership play-off showdown against Bath.

And with the revered Wasps skipper set to retire at the end of the season, it could yet be the final match of an epic 18-year playing career spent at just one club.

To mark the occasion Dallaglio has had a special pair of boots made, inscribed with '1990-2008' to mark the length of his unstinting service at the highest level.

But Haskell - Dallaglio's understudy and back-row colleague - is determined to ensure that after tomorrow the old warrior will need to strap on the armour one final time.

"We have to win this game because we're a club built for success and we want to end the season with a trophy," he said.

"But more importantly we can't have someone like Lawrence Dallaglio, who has won everything, and let him down by not at least reaching the final.

"We have to make sure he bows out the way he wants to. Losing a semi-final would be a disappointing way for a legend of the game to disappear into the ether.

"We'll focus more on this before the game. I expect it to figure heavily in his team talk - he'll remind us this could be his last match."

Dallaglio's impending retirement will leave a vacuum at the heart of Wasps that will be impossible to fill.

Probably more than any other figure at Adams Park he has driven the thirst for silverware, leading the club to three Premiership titles and two European Cup crowns.

Haskell - a possible heir to Dallaglio's throne if he finds a solution to his ongoing contract dispute - explains how the 35-year-old has become synonymous with Wasps.

"Lawrence's attitude is incredible. He has won everything and leads by example," he said.

"Off the field he's been through it all as well, so if a younger player needs advice on anything he is a great guy to help.

"I was five when he started playing rugby! He's been such a consistent stalwart of the team. He gives 100 per cent all of the time.

"In terms of leadership I'd never want to copy him as I'd like to do things my way. But there is definitely so much I could learn from him."
