Ireland coach Declan Kidney praised centre Brian O'Driscoll after the veteran put in an excellent performance in the win over Wales.
O'Driscoll created and scored a try as Ireland dominated the opening 50 minutes in Cardiff, before Wales hit back with three tries of the own to cancel out Ireland's impressive 27 point lead.
Former Ireland captain O'Driscoll has hinted that this Six Nations could be his last, but Kidney hopes that he may stay on for another season.
"Brian will make up his own mind. I would not like to sway him one way over the other," said Kidney.
"The bottom line is you would love to have the guy around forever wouldn't you? But if you look at the performance he put in today, that is not easy on the body.
"Huge credit to him, given the amount of game time he has had, to come out and give such an international class performance like he did today.
"It is wrong to say it doesn't surprise you, as normally you should not be able to pull out a performance like that with the amount of game time he has under his belt.
"With Brian it is just a privilege to be working with him."
Kidney however refused to discuss the possibility of a Grand Slam, despite Ireland boosting their chances and now facing both England and France at home.
"I don't buy into that because it means we should not bother every other year as we have no chance.
"If you look at the second half here, we still have a lot of work to do.
"England and France are playing well and we still have to go to Murrayfield where we lost the last time we were up there."
