Wales number eight Taulupe Faletau believes winning this year's Six Nations title would be a bigger achievement than two years ago.
Warren Gatland's side lost their first match of the tournament to England on home soil but have got their championship aspirations back on track with away wins against Scotland and France.
Next they host Ireland, the only unbeaten side in the competition, with a victory essential if they are to have any chance of winning a third title in four years.
Remembering how Wales were written off after a loss to Ireland at home in 2013, before going on to win the title, Faletau said that replicating that achievement would be an even greater success.
"2013 was great and the win against England at the end was probably the most satisfying I've had," Faletau told the Press Association.
"To lose the first game in 2013 [to Ireland] and to have people on your backs and knocking you down… then to come back from that as a team was great.
"When the final whistle went against England it was amazing, but if we could replicate that it would probably be even better. Just doing it again I think would make it better."
Wales will hope to get an edge on Ireland in the set-piece after a strong showing against France, when their scrum was competitive.
"The boys put a good shift in and we got the result we wanted in Paris," added Faletau.
"It was a good day at the office for the pack and the platform we had at the scrum, especially for me, was noticeable.
"It's what we want going forward and the longer we spend together the more we seem to get better. Hopefully we can build on last weekend and keep our tournament alive."
