Fly-half Alex King described victory over Leicester in the Heineken Cup final at Twickenham as "the greatest ever performance by a Wasps team".
King scored 12 unanswered points in the second half
King slotted 15 points from the boot in a 25-9 win in front of a record 81,076 crowd to deny Leicester the Treble.
He told BBC Sport: "Leicester have had a phenomenal season, but we'd had three weeks off and had done our homework."
Skipper Lawrence Dallaglio added: "We performed when it mattered and in all areas, especially scrum and line-out."
Scrum-half Eoin Reddan and hooker Raphael Ibanez crossed for first-half tries and Leicester were unable to find a way back against a resolute Wasps outfit who led 13-9 at the break.
And following their success against Toulouse in 2004 it draws Wasps level with Leicester on two wins apiece in Europe's premier competition.
"We couldn't let Leicester get too much supremacy over us in the professional era," added Dallaglio.
"They've had a fantastic season, have won two trophies and are worthy champions, but today was all about Wasps.
Fraser Waters epitomised the backs and Joe Worsley epitomised the forwards.
"You've got to feel for them because they come into this game having won two titles and everyone is talking about them walking away with the Heineken Cup.
"Yet they're playing a club with the pedigree of Wasps who know how to win on the big stage.
"That pumped us up a lot, but the ultimate respect we paid to Leicester was the way we trained all week and there were immense performances from everyone.
"Fraser Waters epitomised the backs and Joe Worsley epitomised the forwards.
"And then there's a guy like Tom French coming inagainst Julian White, one of the best scrummagers in the world, and he got the better of him for most of the game."
The crowd was a world record for a club game and King said that helped make this European victory more satisfying than 2004, which was also at Twickenham.
We talked about mixing the game up and not being predictable and it worked

"Everyone wrote us off and that is the greatest motivation - it was a fantastic performance," he added.
"We put them under pressure and that was our tactic. If you let them play they're phenomenal.
"It was special in 2004, but Leicester have dominated all year so to beat them at Twickenham in front of 82,000, it doesn't get any better than that."
Wasps director of rugby Ian McGeechan echoed King's sentiments after landing his first Heineken Cup title as a coach.
"To bring a club to Twickenham when it's full like this and to come and win against a side like Leicester, who were dominating everything, was really pleasing," he told BBC Sport.
"We talked about mixing the game up and not being predictable and it worked.
"The pleasing thing is that after half-time Leicester didn't score. The boys were outstanding."
Flanker Joe Worsley said: "We've not been a consistent team this year, but on our day we're awesome."
