Leinster will endeavour to show their ruthless streak when they tackle Heineken Cup opponents Racing Metro in Paris on Friday night.
The Irish heavyweights, European champions in 2009, have already booked a quarter-final place after dominating a qualifying pool that also includes French champions Clermont Auvergne and Saracens.
But victory at Stade Yves Du Manoir would seal a home draw for Brian O'Driscoll and company, leaving them in pole position to make another concerted tilt at Heineken silverware.
"We have to win in Paris to get a quarter-final at home, and we will certainly endeavour to do that," said Leinster head coach Joe Schmidt.
"I got asked six months ago how many points would win this group, and I said it might be 15, it might be three home wins and a few bonus points.
"So I am delighted with where we are, and now it is about keeping our feet on the ground and not wasting the opportunity we have got."
Leinster's hopes are boosted by the return of centre Gordon D'Arcy, who missed last weekend's 43-20 success against Saracens due to a calf muscle strain, with one other back division change seeing scrum-half Isaac Boss replacing Eoin Reddan.
Rhys Ruddock, son of former Wales coach Mike Ruddock, starts in the back-row alongside Shane Jennings and Sean O'Brien, completing a week when the 20-year-old also gained a place in Ireland's RBS 6 Nations squad.
