Wasps boss Ian McGeechan:
"It was by far the worst display of the season. We gave away a lot of soft points and it was a poor performance without any redeeming features.
"I don't think we were mentally there tonight and you simply cannot afford to be off your game by three or four percent because every opposition in the Premiership is pretty strong.
"The main target for us is the play-offs but we're disappointed with ourselves tonight because we've played poorly."
