Writing in his column for the Wales on Sunday, Barry John is confident Wales are on the right track.
"Wales claimed the big scalp they wanted... and it really is onwards and upwards for Warren Gatland’s team after this.
"Despite two wins on the road, the fantastic Welsh fans still weren’t totally convinced their side was back on track.
"They needed evidence of that from a win against a better rugby nation than Scotland or Italy, although our own triumph in Rome last time out was put into a little more perspective by France’s failure out in the Italian capital.
"But yesterday we finally got the victory, and the performance, we needed to see, achieved against a formidable Ireland side who have proved themselves to be a force at world level in recent times."
