Bernard Jackman believes Ireland will want to make a statement with their performance in this Saturday's Rugby World Cup warm-up against England at the Aviva Stadium.
Andy Farrell's side continue their prep for next month's tournament in France when they welcome their Six Nations rivals to Dublin on Saturday, having claimed a 33-17 win against Italy in their previous outing two weeks ago.
Ireland come into the meeting on an 11-game winning run, having beaten England 29-16 when the sides last met in March.
The Six Nations champions ran in four tries on that occasion, but three of those scores came in the final quarter as they struggled to break down a scrappy England side, who had been down to 14 players since Freddie Steward's red card on the stroke of half time.
"I think they [Ireland] were very, very frustrated with how they played in the Grand Slam game," Jackman told the RTÉ Rugby podcast.
"They won, but there was a red card and they just didn't fire at the same level, and that's been something they've talked about a lot."
The Irish management team are expected to pick close to a full-strength side, having given a number of fringe players a chance in the previous win against Italy.
And Jackman says with next week's friendly against Samoa in Bayonne likely to be a very different style of game, Ireland are more likely to target this week's visit of England as a chance to flex their muscles.

"They haven't really put England to the sword to the level they have other teams. They will expect to show quite a bit this week, in terms of their attack and defence and add to Italy [win] and build a bit of momentum.
"That Samoa game could be stop-start, it'll be tricky enough. This will be the last real chance we have."
Steve Borthwick's side have been far from impressive in their opening two games of the warm-up cycle, beating Wales 19-17 last weekend having lost 20-9 to the same opposition the week before.
Fiona Coghlan joined Jackman on the RTÉ Rugby podcast, and says the 2019 World Cup finalists have offered very little attacking threat.
"I think England would hope they'd be further along in their attacking shape at the moment, its been pretty non-existent. They haven't fired at all," she said.
"I think obviously players coming back in, the likes of [Ollie] Lawrence and [Joe] Marchant bring the direct ball but they've no real game players aside from what [Owen] Farrell brings.
"They spoke about how hard they're going [in training] during the week, and that's why they're sloppy and off-pace at the weekend, which just doesn't seem like they've planned it well. They're obviously planned to peak in that first game against Argentina [at the World Cup] because they have to. Ireland have the lead-in, and will be looking to peak later on in September."
And the former Ireland captain expects to see Ross Byrne given the start in the out-half shirt, having sat out the opening warm-up game against Italy.
"I think Byrne has to be given the start and see how he goes. Then maybe [Jack] Crowley will get on and we'll see how he'll do, but I don't think Byrne will have as quick a ball as Crowley had against Italy. I think it'll be tougher at the breakdown even though England aren't exactly firing at the moment.
"I think Farrell was frustrated at times in the Italy game that it was sloppy, so I'd assume two weeks after that you can expect Ireland to be way sharper," she added.
