Wasps boss Dai Young questioned some of the decisions made by referee David Rose after seeing his side's Aviva Premiership play-off hopes dented by a dramatic 26-24 defeat to Northampton at a snowy Adams Park.
Northampton's rolling maul was a dominant force throughout and a penalty try, further scores from Lee Dickson and Dylan Hartley - plus four points from Stephen Myler's boot - gave them a 19-16 half-time lead. But Tom Varndell's try, two penalties and a conversion from Stephen Jones and a three-pointer from Elliot Daly kept Wasps in it.
Centre Daly's wonderful finish down the left, after another Jones penalty, had then briefly put them on course for a remarkable victory, only for Christian Day to get the crucial fourth try at the death, with Myler's conversion sealing the win. Young said: "They were dominant up front, that was their one weapon."
Young, whose team had three players sin-binned in the match, added: "They did not try and play, or need to play, any other way.
"You will always struggle to win any game if you cannot stop a driving line-out. We were better in the second half, but in the last 10 minutes I felt penalties would come from somewhere to put us inside our own 22.
"I had issues with quite a few (of those penalties), the last three in particular, but it does not change anything. It's no good me sitting here throwing stones at the referee. It doesn't change anything. We just have to move on, but everyone in the stadium never felt we were going to be allowed out of our half (in the last 10 minutes)."
Saints rugby director Jim Mallinder was unapologetic for his side's direct approach and, in contrast to Young, praised the performance of referee Rose.
He said: "We would have been kicking ourselves if we had not have won. But a team like Wasps can score points very quickly and we gave away too many penalties to allow them to keep the scoreboard ticking.
"Our maul was exceptional and it was an area we targeted. Conditions can change and you have to have more to your game than that, but the conditions were bad out there. It was blustery, it was snowing and if you have a weapon like that then why not use it?
"I thought David Rose refereed that part of the game particularly well, although I am sure Dai Young may say something else."
