Dai Young thinks there is more to come from Wasps but they were still clinical enough to run in six tries against play-off rivals Harlequins for a sixth straight Aviva Premiership Rugby success.
In an entertaining encounter at the Ricoh Arena, Wasps managed three tries in each half, with Jake Cooper-Woolley, Christian Wade and Nathan Hughes going over in the opening 40.
Quins had a first-half try from Luke Wallace and looked like they might come back into it when Charlie Walker crossed early in the second half.
However Thomas Young’s try on the hour put the game beyond doubt, while sealing the bonus point, and Wasps rubbed salt in the wounds with two more tries from Siale Piutau and Brendan Macken.
They now sit third in the table, and are well-placed to reach the play-offs, however Young feels they can improve.
“At times I thought we were scrappy, we had a lot of possession in the first 20 minutes and that last pass that stuck against Saracens, didn't quite stick. We bombed two or three opportunities, but between 20-30 minutes, I thought that was a pretty good period for us.
“That enabled us to get a couple of tries and give ourselves a little bit of breathing space. I do think we were a little bit scrappy and became a little bit individual on occasions rather than keeping to our structure.
“You have to beat Quins off with a big stick, every time you play them, they’re always a threat and always going to keep coming back at you.
“We lost a bit of that momentum in the first period of the second half but we give Quins a bit of credit for that. I was pleased we held out and I thought that fourth try was really important for us.
“If they had sneaked another one before that, it could have been back to Conor (O’Shea) and my worst nightmare and another possible nail-biter.”
It was a frustrating afternoon for Harlequins, who missed the chance to move back into the top four with this loss.
They now sit sixth in the table, albeit with just three points separating them and Leicester Tigers in fourth.
And O’Shea remains confident that his team will be able to bounce back quickly.
“I have to say, I thought Wasps were outstanding, sometimes you lose some games and we're very proud people and don't like being on the end of big loss.
“We lost a lot of collisions and we won a fair few too but the ones we lost cost us a heck of a lot more and they have a lot of bullets to fire at you and they are in a rich vein of form, but we will dust ourselves down and there was no doubting the work ethic going in from our players there.
"In many aspects, we didn't get many breaks and you tend not to when you’re on the back foot and there were times when we worked our way back into the game and gave ourselves a few opportunities but the proud nature of sport is you don't like to be on the end of a result like that.
"We have to make sure we get ourselves right back into it next week, as there are probably six teams fighting for two spots behind the front two and it's going to go right to the wire as we all have to play each other, so we're not despondent by any stretch of the imagination and we'll be ready for the next game against Sale."
