Dai Young reckons Wasps were good value for their European Champions Cup win over Leinster

Wasps director of rugby Dai Young reckons his side were good value for their 33-6 victory over Leinster in the European Champions Cup.

Charles Piutau crowned a man-of-the-match performance on his European debut with a last-minute try, adding to earlier efforts from Christian Wade and Joe Simpson (47), as Wasps became the first English club to win a European tie in Dublin since London Irish in 2009.

Young acknowledged there was an element of good fortune in Wade's 29th-minute try - a cruel bounce evaded defender Dave Kearney - with Wasps leading 9-6.

"Obviously we had a little bit of Lady Luck with the bounce of the ball. It certainly could have gone either way, I understand that," Young said.

"Even in that period, we were 9-6, and probably good for 9-6. We pretty much deserved to win. I thought we were pretty much good for it right across the board, really."

Young revealed he had been disappointed with his side's tackling in their 25-20 defeat to Leinster at the same venue last year, and that he had worked with his squad to rectify the problem in the build-up to this Pool 5 opener.

"We got taught a real lesson here last season with the tackle area," Young said.

"We tried to commit to the tackle area and pretty much came off second best and lost that battle. They won quick ball, and then got us on the edges pretty much.

"We talked about, unless it's an offensive tackle, or a positive tackle, keep people on their feet really and frustrate them. I think we learned a few lessons from last season."

While Young was buoyant, Leinster counterpart Leo Cullen could only reflect on a poor day for the club, but he believes his side can still progress.

The defeat was Leinster's heaviest at home in European competition since losing 27-10 to Leicester in October 1996.

"It's very frustrating, very disappointing. It's one of the worst days I've had, being involved with Leinster for a long time," Cullen said.

"We're very, very disappointed with the way we've gone about and conducted ourselves today.

"I definitely feel we can qualify. We've lost at home in the RDS before in our first game, and qualified from the pool.

"This pool was always going to be difficult, and we're making life very difficult for ourselves. But it's important that we stand up now and be counted as individuals and as a collective."
