Ireland number Jamie Heaslip says only a win will be acceptable against Argentina on Sunday.
The British and Irish Lion insists that while the side's performance against New Zealand pleased the fans, last weekend's 38-18 loss to the All Blacks was not enough to placate the players and staff.
After frustrating afternoons against South Africa and Samoa, the Irish came to life in the face of the awesome Kiwis, with a dashing display full of ambition and skill against the world's best team.
But Heaslip insists a narrow victory over Samoa was more pleasing despite a performance that was not on a par with last week.
"People patted us on the back after the New Zealand match and said 'you did us proud', but we lost," said the forward.
"Not only that, but we also aided the All Blacks with the mistakes they punished us for and that's very frustrating.
"We did our job best against Samoa because we won. I have to go with the result.
"I don't like to play in a game that's nice to watch but you lose. I don't want to be on the receiving end of losing.
"I want to win and take more satisfaction from winning than losing. I will win a game any which way possible."
Nonetheless, Heaslip believes there is plenty of time to iron out their problems at the set-piece before next year's World Cup.
"You must play consistently at a high standard if you want to win and that's what we're striving to do," he said.
"The set pieces are the launch pad for every team. A good line-out and scrum will go a long way.
"At times we get the better of teams and at times they get the better of us. It's about minimising the times they get ahead of us.
"There's definitely time to get the fundamentals right before the World Cup. We have about seven or eight weeks together in the Six Nations and there will be more time in the summer.
"If you want to win the World Cup you have to turn up for seven weeks in a row in you want to go all the way to the final."
