Tadhg Beirne says Ireland's lineout mishaps are not a concern to the team and is confident that they can be ironed out against Tonga.
The Six Nations champions lost four of 12 throws in the record victory over Romania on Saturday.
In the previous game, against Samoa in Bayonne, five of 21 throws went astray, in what were difficult conditions.
England also managed to disrupt the set-piece in the warm-up clash on 19 August.
"It's definitely not a concern for us," the Munster forward said.
"The Samoa game, the weather was particularly bad. Unless you were there, you probably didn't see how hard it was.
"Defensively, we've been really good in the lineout.
"We have probably just made a few unforced errors that are unlike us in terms of the lineout.
"To me, they're probably easy fixes and hopefully you'll be able to see those improvements this weekend."
Beirne scored two of Ireland’s 12 tries in the rout of Romania, including the last after the team went the length of the field in over-time, eschewing a chance to kick the ball dead.
"You could probably see from everyone's mindset on the field that we were probably going to have a crack from our own line," said 31-year-old Beirne, deployed on the flank against the Oak.
"We felt we could score another try and everyone had that mindset of 'why not have a go?'
"That's why we ended up getting the try from our own line.
"All those moments from the last four years where we've had a lot of conversations in terms of mindset, especially with Gary [Keegan, performance coach] and with 'Faz' [Andy Farrell] and all the coaching staff, they've all probably played a massive part for those moments at the end of games and where our heads are at.
"It's probably why we feel we're in a good place at the moment."
Asked if becoming more ruthless, a phrase used by Farrell after the game, was a set target for the side, Beirne said: "It probably has been over the time Andy has been in charge, since he's been head coach.
"Was it [Fiji in 2022] when they were down to 13 men and we kicked the ball off, and he wasn't happy with us?
"That's probably happened once or twice where he's very much like, 'We're here to play, we go after teams, we have that mindset.'
"He has definitely instilled that in us and it was no different on the weekend.
"We wanted to keep the foot on the throttle from minute one until the end and get as much out of the game as we could.
"You're playing in a group where, hopefully it won't be the case for us at the end of it, but every point will matter in terms of bonus points or even points difference, I don't know.
"We went into that game, first and foremost, to win, but we wanted to put in a performance where once we got going, we didn't want to take the foot off the gas."
The game in Nantes on Saturday is Tonga’s first in Pool B and although they are ranked 15th in the world, Toutai Kefu’s side will be eager to cause a shock.
"I think physicality is going to be top of their agenda," said the Kildare native, who has 42 Irish caps and two with the Lions.
"I think they’re going to come and try and have a scalp off us for sure.
"They’re a serious side when you look at the team on paper. I’ve no doubt that they’re going to have a go at us. They’ll certainly attack us out wide and then they’ll take us on up front as well, and we’ve got to be ready for that.
"Looking at that Samoa game we were quite off it we felt.
"A lot of mistakes, we were disappointed with how our set-piece went.
"Tonga are probably going to look at those areas and come after us in those areas, so we’re certainly going to have to improve massively on those.
"Again, on the weekend just gone, we’re probably still not happy with where we were there, and particularly line-out. So, we’re putting pressure on ourselves to improve that area for sure and it’s another massive test for us.
"We’re just continuing to look to improve and hopefully we’ll be able to do that on Saturday."
Beirne addressed the media while wearing a very smart suit and revealed it was a forfeit for tardiness.
"There's a bit of a dictatorship going on in camp at the moment," he said with a smile.
"We have three lads that call themselves the sheriffs, they’re in charge of any misdemeanours or any fines that need to be taking place within the camp.
"Unfortunately, I turned up a couple of seconds late for a meeting and they decided to fine me. I had to spin the wheel of fortune and I landed on number ones to and from training, hence the suit.
"But, it fell on media day so everyone gets to see me in a nice suit.
"I don’t know if I’m at liberty to say [what the other punishments are] to be honest with you. There’s a few.
"One of the worst ones is I think there’s a silent one-minute dance which is actually probably punishment for everyone sitting in the room as well as it is for the man who has to do it.
"James Ryan, Jack Conan and Dave Kilcoyne [are the sheriffs].
"The reason it’s a dictatorship is because they are claiming they’re above the law. So there could be a French Revolution yet.
"The power’s definitely going to their heads, particularly Dave Kilcoyne. He’s enjoying it a bit too much for people’s liking I think."
