Rory Best believes Ireland will have to "at least match England up front" to have any chance of winning Saturday's Six Nations clash at Twickenham.
The Irish go into Saturday's match still on course for the Grand Slam but Best admits England have dominated Ireland in their last two meetings.
"We need to understand why they have beaten us and [it is because] they have dominated us up front," said Best.
"That's what they base a lot of their game on and pride themselves on."
In 2012, Ireland's scrum disintegrated alarmingly as England earned a 30-9 victory, while Stuart Lancaster's side strangled the Irish pack into submission 12 months ago as the visitors clinched a dominant 12-6 win.
Best, 31, believes Ireland's three most recent displays put them in a "good place" going into the Twickenham clash, but the hooker says all that could quickly unravel if they are unable to compete with an England front five which will be minus injured prop Dan Cole.
"The way we've played this Six Nations and with the players we have, we've got confidence but we're certainly still cautious because we know what England can do," said Best.
"We (the forwards) always see it as set-piece and forward domination winning games.
"Their scrum has been going very, very well and their line-out has been exceptional. We know we need, at the very least, to match that."
Ireland have started to turn good performances into results recently, building on a thrilling performance against the All Blacks in November, when they were eventually beaten 24-22, in the Six Nations.
"There was a bit of uncertainty whether the New Zealand game was a one-off but we've shown a certain level of consistency over the last three games," Best added.
"With that, you have got to take a bit of confidence but we are under no illusions that it is going to be another step up against England.
"It's going to be our first away game under Joe (Schmidt) and with that, there is a little bit of an element of something new.
"Internationals are very tough games to win away from home."
Ireland will complete the Triple Crown if they win on Saturday while England will be involved in their first home game in this year's Championship after losing in France and beating Scotland.
