VIEW FROM THE DRESSING ROOM
Wasps director of rugby Dai Young:
"The first half was pretty disappointing. We were second best in most departments.
"Coming in at half-time, the dressing room wasn't a very happy place to be. We had to step up in every department and we did.
"In the second half, we looked a completely different team. We were far more potent with the ball in hand, defensively we looked far stronger and the forwards stepped up.
"I thought we deserved to win but the bonus point probably flattered us."
London Irish director of rugby Brian Smith:
"There's no reason to panic. It's early doors in this competition.
"We were in front at half-time but we dropped off the pace 55 minutes into the game. That's really disappointing.
"But we have to cop it on the chin. We have to take our medicine, learn our lessons from this defeat and soldier on.
"We have a young group and we've struggled to put a win together. Young lads are only human and that's a problem for us but they're giving it all they've got."
