DAI Young says Wasps will go to Paris full of confidence next Saturday after beating Stade Francais 30-29 at Adams Park today.
The aggregate winner after the two legs will play in the Champions Cup next season, and Young believes his team are well-placed to finish the job.
He said: "First and foremost I'd like to say I'm proud of the players. We all know the quality Stade have got and we went toe to toe with them and showed what good rugby we can play.
"Our Achilles heel was there for everyone to see again, we work hard to score points but make fundamental errors.
"But I don't think it changes a lot. I always felt that we would have to win both games to go through. I never felt we'd have a huge lead leaving Adams Park to go out there and sit back.
"And I think it would be very dangerous to try and sit back against a team with their quality and just hope they don't score too many points, because they're going to.
"The positives are that we showed we can cause them problems, and with a little bit more accuracy and attention to detail I think we can cause them more problems.
"I'd also like to think that some of the fundamental errors that cost us a couple of tries we won't make next week.
"So we're going out there full of confidence and belief. We'll be respectful of how good they are and how big a challenge it is, but this doesn't change anything - we felt we'd have to go out there and win anyway."
That said, Wasps should be crossing The Channel with a healthy advantage after establishing a 12-point lead in the second half.
He said: "They came in with their heads down and it said there is nothing to have your heads down about. You've got to be proud of that performance and take the positives from it.
"We caused them lots of problems and we should have been going there with a ten point lead.
"But that doesn't change anything if we can go out there and win.
"A one point win would be enough for us. It's a big challenge but we will look forward to it and leave nothing in the dressing room."
