Wasps director of rugby Dai Young revealed some well-directed words at half-time had inspired his side to their 34-15 victory at London Welsh.
Young's team clinched their first win on the road in 12 matches - stretching back to October 2011 - after fighting back from 12-6 down at the interval.
He said: "The big two messages at half-time was I asked them to be accurate in both attack and defence and muscle up.
"I felt that if we could do that, then we had the X Factor in our team and the added quality that would win us the game.
"But that quality can only win you the game if you underpin it with accuracy and work ethic.
"It was an honest appraisal of where we were in the first half. It was not kicking over of glasses or anything because that doesn't get you anywhere. It was certainly that everyone knew that you cannot come here expecting it to happen - you have to make it happen."
Welsh head coach Lyn Jones said: "We were quite buoyed at half-time and turning around at 12-6 up we knew the first score after that was going to be important. Nicky Robinson put one over (penalty) and then they squirted over for the first try.
"We came back and got within bonus point area but individual errors cost us again as some boys learnt to step up to Premiership level."
