England lock Steve Borthwick is determined to land a trophy in his final season at Bath, but he insists: "This is not about me."
Borthwick, who has made almost 250 appearances for the west country club, will join their Premiership rivals Saracens this summer.
He could bow out in style as Bath remain on course for a Premiership title and European Challenge Cup double.
Victory over Recreation Ground visitors Sale on Saturday would send Borthwick and company into a second successive Challenge Cup final following last year's defeat to French club Clermont Auvergne.
With Worcester and Newcastle - teams in the Premiership's bottom third - contesting tonight's first semi-final, Bath know the odds are stacked in their favour.
Borthwick said: "I would love Bath to win the tournament and for me to be able to leave them with some silverware.
"I played in Bath's two previous (Challenge Cup) finals, but this is not about me, it is about the group to whom I have an extremely strong attachment.
"This group has been together for several years and worked very hard in overcoming many challenges. Winning trophies would be nothing more than just reward for their huge efforts.
"But we know that we have a big challenge in front of us on Saturday - in fact, it is a formidable challenge.
"Sale attack you with the ball in hand and challenge you defensively all across the pitch.
"Now we are at the business end of the season, when titles are won or lost, we know Sale will also be really up for the semi-final."
Worcester have received a double boost ahead of Friday's Sixways clash against Newcastle, with skipper Pat Sanderson and centre Dale Rasmussen both declared fit.
Sanderson limped off before-half time against Bath last weekend, nursing a dead leg, while Rasmussen has not played since being concussed during Warriors' quarter-final victory over Montpellier almost three weeks ago.
Worcester rugby director Mike Ruddock said: "When we played Newcastle earlier this season, we felt we should have won up at Kingston Park in the league.
"We outscored them two tries to nil, but the deadly boot of Jonny Wilkinson won the game for them on that occasion, and we know our discipline will have to be top drawer."
Newcastle, their league campaign having disintegrated long ago, field a far stronger side than the one crushed 53-10 by Sale on Sunday - the Falcons' seventh successive Premiership defeat.
England trio Wilkinson, Toby Flood and Jamie Noon all return, and acting rugby director Steve Bates said: "This is a competition in which we have done well this season.
"Getting to the final would definitely be positive progress, but only if we win the whole thing could we say we have had a reasonable season, given how the league campaign has gone.
"It gives us a great chance to finish the season on a high, and while we understand this will be a tough fixture away from home, the application and focus of the squad this week has been excellent."
