Ronan O'Gara has fired a word of warning to Ireland ahead of the Six Nations showdown in Cardiff.
Joe Schmidt's men go into the clash knowing a win will give them a chance of winning the Championship against England at the Aviva Stadium next Saturday.
But they face a wounded Wales side who will be focused on restoring pride in their jersey and a relationship with their demanding fans.
"Wales will be licking thew lips after Ireland's performance for the first 40 in Murrayfield," said O'Gara on RTE.
"I think they will identify areas to go after Ireland big time. How narrow our defence was, if Scotland can do that to them I think Jonathon Davies, Scott Williams, Tipuric, I think they will try and play with an awful lot of pace.
"One of the greatest ingredients we had in our time was fear. I think you can derive a performance when your backs are against the wall. I think you have to appreciate where the Welsh players are.
"They are hated in their country at the minute They can't go out of a café without being abused. That is very very powerful. When you are pushed to that limit, the big guys will rise to the occasion. One or two of them might shrink but I think, for me, do not underestimate that.
