The 46-year-old pundit – who won 81 caps for the All Blacks – slammed Ireland’s playing style and tipped his countrymen to put a big score on Joe Schmidt’s side.
Talking to News hub, Marshall explained: “I’m not convinced they’re as good a side as they have been in the past.”
“They’ve got a little laborious in the way they’ve been attacking. They’re predictable.
“The All Blacks will be up for it and I think we could actually see them put some points on them and win quite comfortably.”
