David Denton believes the key to Edinburgh beating Ulster in the Heineken Cup semi-final is him winning his battle with opposite number Stephen Ferris.
Edinburgh have been the surprise package in this year's European Cup with their forwards proving crucial to their progress to the last four of the competition.
Denton will be an important figure for Michael Bradley's side at the Aviva Stadium but the flanker knows he will have to get the better of Ferris if they are to have any chance of causing another upset.
"I've always been confident in my own ability and this weekend's a great test for me," Denton explained. "Ferris is one of the best, if not the best, blindsides in the world at the moment. He's a great player.
"When he gets on the front foot you can see the team rally behind him. I think if I can get on top of him there we'll stand a good chance.
"I've played against Ferris before and a very strong Irish back row and I didn't feel out of my depth.
"That's important. If you can go into a game feeling confident in your own ability and your team's ability, that's the first step."
While they have enjoyed a superb run in the Heineken Cup, Edinburgh have failed to sparkle in the RaboDirect PRO12 and they travel to Ireland in the knowledge that they have already lost twice to Ulster this season.
Despite their two defeats Denton is in no doubt that Edinburgh can get the better of Ulster but he is only too aware of the challenge that awaits in Dublin.
"For one reason or another the Heineken Cup's been going really well for us this year," he told Press Association Sport.
"It's where we've come together as a team and shown what we're capable of. In the Rabo we haven't.
"We're aware of them (the Ulster losses) in the same way that we're aware we haven't had a very successful RaboDirect season.
"If anything it shows how strong they can be so we're not going to be underestimating them.
"Ulster are a very strong team. They've got a lot of strength in depth and a lot of good players. They play a good style of rugby. Their defence particularly is very strong.
"It's going to be a tough game for us, but we showed we could do it against Toulouse and everyone knows how well we can attack when we're on song.
"If we can play close to our best, we're well capable of beating them. It's going to be a big battle for us but it's one we can definitely win."
