Wasps director of rugby Dai Young heaped praise on "outstanding" fly-half Andy Goode after the former England international helped condemn his old club Leicester to a deserved defeat at Adams Park.
Goode kicked 17 points including two crucial drop goals in the second half when his side were under pressure and also played a key role in Christian Wade's first-half try - the only one of the match - as Wasps ran out 22-12 winners.
Young said of the former Tiger, who joined Wasps from Worcester earlier this year: "Andy was outstanding as he steered the ship and kicked the important goals.
"A lot of people have knocked him this season but he showed today why I wanted him to join us."
While Goode played a vital role in the result, Young felt the key to the victory was his side's defensive effort after they lost hooker Carlo Festuccia to a yellow card in the second half.
The Wasps boss also believes that gaining only their second Aviva Premiership win of the season was the most important thing, rather than how the team performed against the reigning champions.
He said: "I never thought the game was safe until three or four minutes from the end. We made it difficult for ourselves in the second half as we allowed them to gain field position.
"Our defence for the 10 minutes that we were down to 14 men, when Carlo Festuccia was sin-binned, was crucial and the difference between winning and losing."
He added: "The result was far more important than the performance as we just had to find a way to win. It was a tough day for our youngsters as they are a wily old bunch up front and those youngsters will have learnt a lot today."
For Leicester, the defeat means they have still not tasted victory in this fixture since 2007 and Tigers director of rugby Richard Cockerill accepted it was an unsatisfactory showing from his side, whose only points came from the boot of Owen Williams.
"We are disappointed; it was a pretty ordinary game with error after error. The weather conditions were difficult but we missed crucial kicks and we went to sleep for their try. These things cost you and our performance was below average," said Cockerill.
The Tigers chief also refused to use the fact his side were badly hit by injuries and England call-ups as an excuse for the performance.
"We have the whole of our first-choice back-line out and a number of key forwards but we came with a side that should have played better. It wasn't a disgrace but I expected a little bit better than that," he said.
