Wasps head coach Dai Young praised the way his side battled back from behind to defeat Bayonne 26-10 in the Amlin Challenge Cup.
Young's team trailed at the break but posted 20 unanswered points in the second half at Adams Park to claim their second straight win of the competition and leave them top of Pool 4.
"We are pleased with the result and very happy with the response in that second half," he told the club's official website.
"Getting two wins under our belts early on definitely gives you more confidence in your group.
"The first half was disappointing and the players felt they let themselves down. We had a bit of a rallying cry at halftime in the changing room.
"We talked about how we'd lost the ball far too often and how we were allowing their pack far too much ball. We clawed our way back into it and I was very pleased with the response.
"The forwards were really good again and in that second half they did a good job at sapping the energy out of that heavy Bayonne pack.
"We are getting better and better as a pack but we know there are bigger challenges to come. Leicester next week will be another big step up for us."
Young was also delighted at the return of England backrow James Haskell, who made his first appearance of the campaign.
"He has worked really hard to get back and he is desperate to show everyone what he can do. His return is a big boost to us," added Young.
"He has huge experience and if he gets back to the type of form we know he can produce that is great for us."
