Nathan Hines reckons Toulouse will be running scared of defending Heineken Cup champions Leinster's line-out.
The Irish province travel to the south of France to face three-time champions Toulouse in Saturday's semi-final.
And British Lions lock Hines, who is in his first season with Leinster, insists their set-piece will be too hot to handle for the French giants.
Hines, 33, said: "If we can replicate our practice in Toulouse I'm sure we will do well on the day. We will have to make sure our set-piece and scrum are strong and our tactics won't change
"Leo is good at winning and stealing line-out ball. It's good for other teams to be fearful of our line-out but a couple of times it hasn't gone well this season.
"London Irish in the first game of the competition wasn't a good game to remember but, in general, it's been an area of strength for us.
"But we know it's only one facet of the game. However, if we can win clean ball up front then it will make life much easier for us as Toulouse are a very good team with a lot of ball players.
"They have many clever and dangerous players, particularly in their back three so we will have to be strong defensively to shut them down."
Leinster have been dealt a major blow after Jonathan Sexton, who booted Michael Cheika's men to a historic final win over Leicester Tigers in Edinburgh last season, was ruled out of the last four tie after failing to recover from a fractured jaw.
Shaun Berne will deputise at fly-half for the Irish giants but Australian-born Hines believes his team-mates are peaking at just the right time of the season to maintain their quest for further silverware.
"A lot of the lads have been injured or rested in the past ten days so everyone has had a break," added former Edinburgh and Perpignan second-row Hines.
"Whereas we knew Toulouse had a tough game against Castres last weekend to book a home play-off place in the Top 14.
"We are peaking for this game and training has been good this week. We could not have prepared any better for this challenge."
Despite the loss of Sexton and British Lions wing Luke Fitzgerald who is out with a long-term knee injury, Leinster include fellow Lions Rob Kearney, Brian O'Driscoll and Jamie Heaslip for the mouth-watering contest against Guy Noves' star-studded side.
The directors of ERC voted unanimously at a Board meeting to postpone all decisions including the release of further instalments of ERC's distributable central revenues to the six shareholder countries until 19 February next when the Board will meet again to reconsider the issue.
