Wales hooker Richard Hibbard says English complaints about the refereeing during the recent Six Nations match between the sides are not being taken seriously by the Welsh camp.
England's hopes of winning a Grand Slam came to an end in Cardiff on 16 March when they were hammered 30-3.
The hosts were particularly dominant in the scrum that day and England forwards coach Graham Rowntree was furious about the number of penalties given against his side at the set-piece by referee Steve Walsh.
And England have even asked the International Rugby Board for "clarification" regarding certain areas of Walsh's performance.
Asked for his thoughts on Rowntree's remarks, Hibbard said: "I can't comment on that but no-one would be happy to lose a game that heavily and get dominated at the set-piece.
"He is looking out for his players ahead of their next game.
"I would like to think we are the most honest scrum around, so to say they were conned is just water off a duck's back for us."
Hibbard is now looking towards this weekend's crucial RaboDirect Pro 12 clash at the Millennium Stadium between his Ospreys side and Cardiff Blues.
Ospreys are looking to secure a play-off spot and Hibbard said: "We need a full house of four wins from our last four games. We don't want to leave it in anyone else's hands.
"It will be tough, we don't have any easy games, so we are not taking anything lightly.
"It was magical at the stadium last week for us to lift the Six Nations trophy, but we are under no illusions. We are going there to do a job and push for a play-off place."
