Scrum-half Rhys Webb hopes Wales do not suffer the same fate against Ireland in the Six Nations as England did.
Webb says England put no pressure on Irish half-backs Conor Murray and Johnny Sexton in their 19-9 defeat in Dublin.
"I don't know if England did much analysis on them - they didn't seem to put much pressure on nine and 10 whatsoever," said Webb.
The Ospreys player says Wales have "no margin for error" on Saturday.
Unbeaten Ireland are aiming to complete the fourth leg of a potential Grand Slam while a win for Wales would keep alive their title ambitions.
Ireland's visit is a chance for Warren Gatland's side to make amends for losing to Stuart Lancaster's England men.
"To win the title would be a massive achievement after the disappointment of losing to England,'' said Webb, who faces Ireland for the first time in a Test.
"We know that we have to beat Ireland to remain in contention.
"To be fair, they have won 10 games on the bounce. They are a world-class team - the best in Europe."
Ireland have only lost twice in Cardiff since 1983 and Webb says success for the visitors on this occasion would be down to more than merely the type of "outstanding kicking performance" that Sexton and Murray produced in Dublin.
"The kick is only as good as the chase, and playing with Bowey [Tommy Bowe] at the Ospreys, every time I put a box-kick up he would always go and get it back for me," said Webb.
"Murray and Sexton are key players, but Bowe, [Rob] Kearney and [Simon] Zebo are good in the air.
"We just need to be on the money, and we know there is no margin for error because Sexton will keep kicking the three points over and he can also put us in the wrong parts of the field.
"We just need to keep on top of it and keep lots of pressure on them.''
