The visitors, still smarting from the defeat in Lansdowne Road found themselves ten points down after Charlie Hodgson converted Steve Hanley's opening quarter. That score came when Shane Horgan had his kick-through blocked but Hanley appeared to be well offside before he raced clear.
Leinster held their composure and had a try in each half from John McWeeney and Brendan Burke and withstood a late bout of Sale pressure to claim the points that sends them to the top of Pool 3.
Former South Africa coach Nick Mallett'shopes of capturing the European Cup with French champions Stade Francaisreceived a welcome boost as they dismantled an ill-disciplinedWelsh side Gwent Dragons 37-0.
Stade avenged their 20-12 defeat in Wales last weekend with animpressive and clinical performance and captured a bonus point for scoring fivetries as Argentine fullback Ignacio Corleto, Pierre Rabadan, captain MathieuBlin with two and an on-fire Christophe Dominici touched down. The victory took them top of the Pool One standings on pointsdifference from two-time champions Leicester, who beat Stade in the 2001 finaland destroyed Ulster in their clash on Saturday.

Blin rounded off a dominant performance against a Gwent side whichreceived three yellow cards by touching down in the corner in time added on. Dominici ensured that Stade secured what could be a crucial bonuspoint when he finished off another sparkling move which involved severalplayers from deep in their half.
Stade had a couple more chances to add to the try tally especiallyafter Gwent were handed their second yellow card of the match but failed tothanks to some sterling Welsh defending.
However Blin made them pay once Adam Black earned their thirdyellow card with under 10 minutes remaining.
His effort was nothing as spectacular as Corleto's stunningopening try. It stemmed from a wonderful passing movement across the pitch, the Argentine got the break he needed as Dominici's lightning quick flickon released him and he outsprinted the covering defence to touch downunder the posts.
Jason Forster's yellow card in the 32nd minute for a high tacklehad also been punished by the French side. A minute later Rabadan had scored his second try of the campaignas the 23-year-old picked up at the back of the scrum and went overunopposed to touch down.
Blin added a third shortly before the break after Stade won alineout and the scrum bundled him over.
