The former England flanker told The Times: "Everything, as I have said, has moved up a notch and I believe this team is ready for Dublin.
"England have moved their game quite a distance from where they were this time last year and after the excellent win over the All Blacks in November, it was really good to see how they picked up against the Scots close to where they left off in the autumn.
"We will learn more about the team from what looks like a potentially cracking Test match in Dublin. Ireland are back on form and there was much to admire about how they played in Cardiff. Of course England haven't won a Six Nations game in Dublin for 10 years but I see that as firing up the team big time."
