Wasps director of rugby Ian McGeechan:
"A lot of credit goes to the forwards. They were outstanding.
"They gave us the platform to control the game, particularly in the last 20 minutes when it was important we gained field position.
"We scored two good tries. There were always going to be mistakes though because it was first-game-of-the-season syndrome."
