Andy Farrell should avoid wholesale changes for Sunday's final Autumn Nations Series game against Argentina (live on RTÉ2 and RTÉ Player), according to Bernard Jackman and Donal Lenihan.
Ireland will look to maintain their seven-game winning streak when Mario Ledesma's side visit the Aviva Stadium this weekend, following impressive performances against both Japan and New Zealand.
The pair believe the two impressive wins this month have given Farrell the opportunity to rotate his selections, however, they insist that a core of the first-team has to be retained in order to make that rotation worthwhile.
"I think Faz will be very aware of how important it is to keep those non-first choices players involved, particularly now that he has a freebie after the All Blacks win," Jackman said.
"I do expect some changes, but also to give those guys the opportunity to show what they can do, you need some cohesion as well.
"You need some consistency."

Lenihan echoed those thoughts: "You have to make changes, but you've got to give the guys coming in the opportunity to have that core element in and around them. For that reason I wouldn't be making wholsesale changes."
With both Johnny Sexton and Jamison Gibson-Park now injured, the likely scenario is that Joey Carbery will wear the number 10 shirt outside either of his Munster team-mates Conor Murray or Craig Casey.
Jackman says Sunday's game will be an ideal opportunity for Carbery to express himself against quality opposition, albeit with less pressure on the result.
"I think it was brilliant he got on against the All Blacks and had three kicks which he nailed to just settle him down, and I think he will benefit from the increased organisation that Ireland are playing with," Jackman said.
"Effectively - and this is a bit of a criticism of Munster - when Munster play this season they haven't had the same options around the 10 that Ireland have for Johnny Sexton.
"Joey is a very instinctive player, so if he's at the back of a pod of three off the scrum-half and he calls the pass out the back, he has the footwork and pace to open up opportunities if there is a dog-leg.
"I think it's an ideal opportunity for him having had a little taste at the weekend but the most important thing is he'll be playing for an Irish team who seem to have more clarity in terms of how they're trying to play and also have more powerful athletes who can hopefully put him on the front foot."
The pair both agreed that Munster back row Gavin Coombes "has to start", having missed out on the opening two games this month due to illness, while Lenihan says he wants to see Simon Zebo get a run at full-back, to make sure Ireland are prepared for any future injuries to first-choice Hugo Keenan.
"I think Zebo is an interesting one given he's been out of the set-up for four years now," said the former Ireland captain and manager.
"We know Hugo Keenan is nailed-on at full-back, but who is the reserve to him? If he gets inured before a game in a tournament, who is the back-up there?
"There's no standout candidate to cover that at the moment. Jordan Larmour was tried in the past, I think that experiment is over, they're looking at him as a winger. I think with Keenan having played 15 games in a row, this might be the game you put Zebo in."
Up front, Jackman is hoping to see Finlay Bealham get the opportunity to start, while he also wants Leinster hooker Dan Sheehan get another Test match experience off the bench.
"In terms of bodies, I'd love to see Sheehan get some more game time, maybe that's off the bench because you want to be loyal to Herring who will give you good set-piece," he added.
"I need to see Finlay Bealham play more, and that would be the concern.
"We know what Church (Cian Healy) can do, and it's crazy to say it, but Porter is still re-learning his trade at a loosehead, so I don't mind if he starts because it gives you some consistency."
