Donal Lenihan feels the performance of Ireland's back three against Wales is a good sign as they look to build on back-to-back wins in the remainder of this Guinness Six Nations campaign.

Andy Farrell's side saw off the visitors 24-14 at the Aviva Stadium with full back Jordan Larmour and wing Andrew Conway scoring tries and Jacob Stockdale more involved than in the previous week's victory over Scotland.

It was that extra level of involvement with ball in hand that impressed ex-Ireland and Munster man Lenihan most as he told RTÉ Sport at full-time.

"The amount of times the back three got the ball in their hands - the likes of Conway, Larmour and Jacob Stockdale - augurs well," he said.

"There was a definite shift in the way Ireland were looking to attack.

"I thought the midfield as well, Robbie Henshaw up to the point that he had to go off with that head injury, I thought he was having a really big game.

"And on the flipside, the closing 20 minutes, the fact that Ireland again having weathered a bit of a Welsh storm, they got back into the Welsh '22.

"They got that brilliant try off the line-out and the confidence of Andy Farrell to bring on the young fellas with ten minutes to go.

"You take off your captain and your vice captain, Ross Byrne came in and great to see [Max] Deegan getting his first cap and of course the final try from Andrew Conway was the icing on the cake."  

Overall, Lenihan saw plenty of positives from Ireland in a much improved display.

"It was very pleasing I have to say," he said.

"You look at the pressure Ireland were under in the opening 20 minutes in terms of they had loads of possession, loads of territory but Wales were dominating at the breakdown. 

"There was a concern earlier on that having made so many entrances into the Welsh '22, their dominance wasn't being reflected on the scoreboard. To be fair, once they got that opening try, [Ireland pushed on]. 

"And again we saw good variation in terms of using Jordan Larmour with brilliant feet from him and a great opening try.

"So I thought there were a huge amount of positives from Ireland today."
