Leinster lock Devin Toner knows that Italy number eight Sergio Parisse will be the heartbeat of the Stade Francais plan to cause a shock in the Amlin Challenge Cup final at the RDS on Friday night.
"Obviously, they have (Sergio) Parisse at the back, he's got skills all over the park, but he's also one of their main line-out options," Toner (pictured) said.
The Stade pack will also be huge, bringing a big, mauling set of forwards to eat up the yards and the clock.
"The two second-rows will probably be (Gerhard) Mostert and (Scott) Lavalla, who played for years for Trinity. So Scott will probably know a little bit of what we're about in terms of how we play.
"They drive nearly 80-90 per cent of the ball so we'll really have to look at the maul. We've done a lot of homework on them."
Toner has started to thrive recently on the game time earned from coaches Joe Schmidt and Jono Gibbes, alternating with Quinn Roux to partner club captain Leo Cullen.
"If you get a bit of confidence from the coaches to play in the big matches, that confidence leads into playing well, I suppose, and being involved in a lot of things. I've a fair bit of confidence from the last couple of weeks," he said.
"You know yourself if the coaches have confidence in you, if they're involving you in certain moves. They have been having a word in my ear to give me confidence.
"Game time is huge, if you're getting game-time it builds up confidence," said the 6ft11 second row.
"At the start of the year, I was looking at cementing a starting role in the team. So if I can get a start in either of these finals, that's something that can build up your confidence.
"If I get the nod, it's a good indicator of how I've done this year, and a reflection that the coaches have confidence in me."
