Noise from the Japan camp about the Irish scrum is a sign that they are worried, according to former Ireland prop Mike Ross. 

Tighthead prop Yusuke Kizu made a point of commenting on Cian Healy's technique ahead of Saturday's World Cup Pool A clash in Shizuoka. 

"Their loosehead prop steps out, so they try to attack from the side, that's my impression of their scrum," said Kizu.

"I'm delighted to hear them talk about it because generally if a team comes out with a statement like that they are usually worried about something, the fact that they are trying to put on pressure through the media," Ross, capped 61 times for Ireland, told RTÉ Sport. 

"As to whether or not there is any truth in that? I wouldn’t think so. I often thought that when I was playing with Cian he wasn't illegal enough. He could do a lot more damage if he scrummaged a little less straight."

The ex-Leinster player added that, even if Joe Schmidt makes a number of changes, it wouldn't be in Japan's best interests to go toe-to-toe with the Irish pack.

"If you look at our scrum over the last two years it’s been very disciplined and we haven’t suffered at the hands of referees.

"From what I've seen a lot of their game plan involves keeping the ball alive and trying to run lads off their feet and they certainly have the personnel to do that, their domestic game is geared that way,

"But there would be a difference in starting pack weights so they wouldn’t want to get into an arm wrestle.

"They’d be more interested in keeping it looser and making Ireland run but given what I saw of Ireland’s conditioning at the weekend I don’t think that’s going to be a problem.

"I think you could change four or five guys without negatively impacting what you have. Rory Best played 80 minutes against Scotland so he’s probably a good guy to rest.

It turns out @MikeRoss03 also had some issues with @ProperChurch's technique #JAPvIRE #RTERugby #RWC2019 - Read more here https://t.co/LpCS3kdyoQ pic.twitter.com/viiavcPKq0

"There is an argument you could have a look at other back row guys, Jack Conan and Rhys Ruddock.

"There is a lot of quality left out of the the squad and they want to have their opportunity.

"Japan would be one of the better teams in the group so it’s a good way to have a look at the guys who didn’t start to see if they can put their hands up for selection in subsequent games."
